Executive Summary

The National Renewable Energy Laboratories (NREL), in cooperation with the US 

Environmental Protection Agency (USEPA, or EPA), determined the need for an evaporative 

emissions test program to characterize real-world evaporative emission events for planning and 

inventory modeling purposes. This program (E-77-2c) adds testing on E20 (20 volume percent 

ethanol in gasoline) on additional vehicles to the E0 and E10 fuels previously evaluated in the 

CRC E-77 series studies, as well as additional implanted leak mechanisms.

“Permeation” refers to the loss of fuel vapor through the various components of a vehicle’s fuel 

system. Permeation occurs continuously, but the rate depends on a number of factors, including 

the properties of storage container (gas tank, etc.), type of fuel hoses (material, design, shape), 

the amount of fuel in the container, environmental factors (including temperature) and fuel 

properties (including oxygenates). Diurnal emissions are those that occur daily, or over a 24-

hour period of testing, and are measured while the vehicle’s propulsion system is at rest.

An additional part of this program was to expand on the leak study performed in E-77-2, with 

additional “implanted leak” evaluations on vehicles 207 and 211. Previous evaluations were 

made with leaks implanted at the fuel cap. For this program, leaks were implanted at the top of 

the fuel tank, and separately at the canister’s fuel vapor entry with 7 and 10 psi E10 fuel. This 

assignment was known as Task 4.7.

The fuels used to evaluate the permeation performance of the vehicles in Task 4.5 and 4.7 were 

20 volume percentage ethanol mixtures, at two vapor pressures, seven (7) and nine (9) psi RVP. 

Task 4.5 measured the permeation performance of the two vapor pressure fuels on the selected 

fleet. Task 4.7 continued a previous CRC investigation into the emission effect of implanted 

leaks in the vapor system.

The following table summarizes the fleet as tested in the E-77-2c program. One vehicle, No. 

220, a 2000 model year (MY) Chevrolet Malibu, started the test program; but was cancelled by 

the steering committee when it exhibited a deteriorating leak condition during the program.

vii

This assignment (E-77-2c) only involved the performance of permeation measurements on 

vehicles operated on two E20 fuels. The main value of the data collected is realized when the 

results are viewed in the context of the prior CRC work. There are three sections in the 

“Discussion” portion of this report: 

The permeation performance of the “Combined E-77 Fleet” on the various fuels (Task 

4.5 plus prior work). 

The additional leak testing that was done in this project, combined with the prior work to 

overview the effect of leak location. It also points out that the later vehicles with ORVR 

systems had different leak effects. (Task 4.7 plus prior work)

Description and details of the evaporative emission speciation measurements, and the 

methodology of the “Average Reactivity” calculations that were made. 

Task 4.5 demonstrated that while the sample sizes are still too small to make comparisons with 

statistical significance, several trends are suggested. Referring to the data presented, and 

comparing the average permeation performance for various groups, the following trends and 

observations are offered:

The newer Tier 2 vehicles have lower permeation than Tier 1 on all fuels.

Permeation is higher with E10 or E20 compared to an ethanol-free (E0) fuel.

The tests performed for Task 4.7 demonstrated two findings that may have significance for air 

quality modelers:

Vehicles fitted with ORVR systems may have changed the emission impact of a small 

leak at the fuel cap. Leaks added at the fuel cap for the two ORVR vehicles tested 

produced one day diurnal emissions almost an order of magnitude lower than was seen 

with a previously tested non-ORVR Cavalier. This change in the emissions measured is 

thought to be due to the addition of “check valves,” or “anti-spitback valves” added to the 

systems to improve the fuel fill control.

Diurnal emissions measured with leaks implanted at the top of the fuel tank, or at the 

entry to the carbon canister, were significantly higher than the emissions with a leak 

implanted at the fuel cap on the two ORVR-equipped vehicles tested. It was expected 

that the permeation emissions from a leak at the top of the tank might be higher than 

those from a leak at the fuel cap.

The E-77-2c scope of work request included gas chromatographic speciation of all the 

vehicle tests, including the static tests, the dynamic, and the diurnals on both fuel vapor 

pressures. This generated a sizable file of test results. Analysis, or comment on the content 

on the speciation other than the calculation of reactivity was not attempted, and is beyond the 

scope of this investigation. The detailed speciation summaries are presented at the end of this 

report in Appendix IV.

Introduction

Background - The National Renewable Energy Laboratories (NREL), in cooperation with the 

US Environmental Protection Agency (USEPA, or EPA), determined the need for an evaporative 

emissions test program to characterize real-world evaporative emission events for planning and 

inventory modeling purposes. Coordinating Research Council’s (CRC) “E-77 Pilot Study1”

demonstrated that segregation of evaporative emission components was possible, where fuel 

system permeation emissions were measured separately from fuel tank and carbon canister 

venting emissions. Later CRC studies, E-77-2

2

, and E-77-2b3, continued these measurement 

techniques, and added to a data base that was created to support new concepts in air inventory 

modeling. This program (E-77-2c) adds testing on E20 (20 volume percent ethanol in gasoline)

on additional vehicles to the E0 and E10 fuels previously evaluated in the CRC E-77 series 

studies.

“Permeation” refers to the loss of fuel vapor through the various components of a vehicle’s fuel 

system. Permeation occurs continuously, but the rate depends on a number of factors, including 

the properties of storage container (gas tank, etc.), type of fuel hoses (material, design, shape), 

the amount of fuel in the container, environmental factors (including temperature) and fuel 

properties (including oxygenates). Diurnal emissions are those that occur daily, or over a 24-

hour period of testing, and are measured while the vehicle’s propulsion system is at rest.

An additional part of this program was to expand on the leak study performed in E-77-2, with 

additional “implanted leak” evaluations on vehicles 207 and 211. Previous evaluations were 

made with leaks implanted at the fuel cap. For this program, leaks were implanted at the top of 

the fuel tank, and separately at the canister’s fuel vapor entry with 7 and 10 psi E10 fuel. This 

assignment was known as “Task 4.7.”

Contract History and Period of Performance - Harold Haskew & Associates, Inc. (HH&A)4

was awarded the contract for this program, and shared the testing responsibility with Automotive 

Testing Laboratories, Inc. (ATL)5in Mesa AZ. The contract was dated June 1, 2009, and the 

first test was conducted on August 12, 2009 (Task 4.7 leak test on Vehicle 211c with the E10 

fuel). Weekly progress reports were made each Sunday, with Number 1 dated August 9, 2009, 

and the final, number 31, dated March 4, 2010.

Test Procedures

A Test Method for Separating Permeation from Tank Venting and Leaks – In a previous 

CRC Project (E-65), the laboratory separated the canister loss from the permeation measurement 

by venting the losses from the carbon canister 

outside the SHED. For Project E-77, the canister 

vent losses were collected and measured in a 

separate “trap canister” on a scale outside the 

SHED, as shown in Figure 1. This vent line was 

capped off, i.e., sealed during the Static Test, but 

connected as shown in the figure for the Dynamic 

and the Diurnal Test. The ambient temperature in 

the SHED was constant during the static test, and 

there was no vapor created at constant 

temperature. This vent was closed to pressurize 

the system for the leak evaluations. The resulting 

SHED increase in HC mass was permeation6. The 

last mechanism that needed to be evaluated was leaks. Leaks can be both vapor and liquid. A 

liquid leak can have significant mass, currently undetected by the vehicle’s on-board diagnostic 

system. Considerable thought and effort have gone into the creation of a simple and effective 

liquid leak detection methodology, without success. The techniques used in this project required 

the use of a SHED for measurements. The techniques were not simple, but they proved 

effective.

Based on experience, a vehicle’s permeation rate is expected to lie between 4 and 90 mg/hour. 

The presence of a static liquid leak is expected to overwhelm this value; such a leak would (or 

could) be apparent by inspection. Leaks from the vehicles were quantified in a three-step test 

process. The first step was to measure the static permeation rate of the vehicle at 86oF. The 

vehicle was allowed to stabilize at 86oF in the SHED and the permeation rate was calculated 

from the mass increase in the SHED. The second part of the test, looking for pressure driven 

leaks in the vapor system, was performed by pressurizing the vehicle’s tank to 5” H2O through a 

special fuel cap and tubing from outside the SHED (Figure 2). The special fuel cap, the hose and 

the pressurization apparatus was installed before the start of the sequence. The HC concentration 

in the SHED was monitored, and the increase in the mass of HC in the SHED was compared to 

the static permeation rate. If there was no (or insignificant) rate of increase, it was deduced that 

no vapor leak is present.

 

6 This is a simplification. There are other HC sources present that are not fuel permeation. These include tire, paint, 

adhesives and vinyl emissions, and the possibility of fuel leaks from the fuel injectors. The investigators believe 

these to be a minor component of the emissions measured in this study. 

Figure 1 Trap Canister
Final CRC E-77-2c Report - Dec 2010

6

The third and final part of the test was to energize the vehicle’s fuel pump and pressurize the 

system up to and including the injectors (Figure 3). If there were a pressure leak in the liquid 

system, an increase in the SHED mass over time would be seen, i.e., the leak would be additive 

to the permeation rate. 

Figure 3 Static Test – Fuel Pump Energized

Other Tests (Dynamic, Hot Soak, and Diurnal) - A similar configuration is used to isolate the 

tank venting losses from the permeation measurements determined by other test procedures. The 

vehicle’s canister vent is connected with a low permeation hose (TeflonTM) to a bulk-head fitting 

in the SHED wall and then to a separate “trap canister” on a top-loading scale. Any HC 

emissions that escape from the vehicle’s canister are captured in the trap canister, and measured 

at a 0.01 g (10 milligram) precision. The trap canister (a 1 Liter Ford model) is purged before 

each test and maintained at a “dry” condition so that it captures all of the vehicle’s escaping 

emissions. This assumption is probably violated during high vapor pressure tests where there are 

30 or more grams of daily emissions.

E-77-2c Vehicle Selection

The vehicle mix was specified in the CRC Request for Proposal as eight vehicles for Task 4.5, 

and a repeat of two vehicles previously tested in CRC programs with implanted leaks for Task 

4.7. Task 4.5 vehicles included five Tier 1 vehicles, two Tier 2 vehicles, and one “Zero Evap” 

vehicle. 

Table 3 summarizes the fleet as tested in the E-77-2c program. One vehicle, No. 220, a 2000 

model year (MY) Chevrolet Malibu, (not shown in Table 3) started the test program; after 

exhibiting a deteriorating leak condition during the program, it was cancelled by the steering 

committee.

A “Tier 1” vehicle is one that certified to the EPA’s “Enhanced Evaporative Emission” 

standards7. These evaporative standards were phased in starting in Model Year 1996 (see also 40 

CFR 86.096-8 (b)), with all light duty vehicles compliant by MY 1998. Vehicles certified to the 

evaporative emissions standards prior to the enhanced standards are referred to as “Tier 0.” The 

enhanced standards required control of diurnal emissions for up to three days (previously a one 

day tank temperature rise, compressed into a one hour time requirement), as well as control the 

evaporative (i.e., non-tailpipe) emissions during vehicle operation (known as running losses) at 

high (95°F) ambient conditions, and a one-hour “high-temperature hot soak” period immediately 

following the drive. Tier 2 standards8used similar test procedures and conditions, but lowered 

the allowable limits to less than half the previous standards. California required that a fraction of 

the vehicles produced for California meet new “Zero Evaporative Emission” standards.9 A 

vehicle certified to the zero evap standards had diurnal plus hot soak fuel emissions at levels less

grams, or 54 milligrams, to include round off of the measurement. A whole vehicle performance 

limit of 350 mg/test was included to allow for non-fuel test contributors (e.g., tires, adhesives, 

etc.) on a whole vehicle test.

Composite Vehicle Fleet

As stated previously, the Task 4.5 of the E-77-2c program added seven vehicles tested on E20 

fuel to the E-77 program database. Table 4 below lists the “composite E-77 vehicle fleet,” sorted 

by evap standard, with the 2c vehicles indicated by the “/c” notation in the vehicle number 

column of the light blue rows. Not all data from the composite fleet are usable for later analysis, 

as the use of the INNOVA analyzer for identification of methanol (probably from windshield 

washer fluid) and refrigerant (R-134a) leaks did not become available until the latter part of the 

Pilot Program. Pre INNOVA data tests that were not used in the analysis are indicated with the 

yellow shading.

It seemed desirable to combine as much as possible of the previous E-77 data (E-77 Pilot Study, 

E-77-2, and E-77-2b) with the newly gathered data into the discussion of results. Not all of the 

data were comparable. The following summary is offered to explain the various choices. 

While not part of the contracted E-77 Pilot Study, the laboratory found that the vehicle 

tests needed to be corrected for the presence of the methanol and the refrigerant R134a. 

The INNOVA analyzer that the laboratory purchased and used to make these corrections 

was not available for testing until vehicle 006. Of the remaining vehicles tested, only 006 

and 008 were Tier 1 models. (Vehicle 007 was an implanted leak test, and vehicles 009 

and 010 were pre-enhanced Tier 0 models.) The Pilot Study only ran a one-day diurnal, 

rather than the three-day test that became the norm.

The 105oF static tests were first introduced in the E-77-2b test sequence to enhance the 

evidence that permeation is directly affected by temperature. The earlier test programs 

did not have that information.

Emission results are presented in later sections of the report for each of the four evaporative 

emission elements (static, running loss, hot soak and diurnal), with data averaged for selected 

and representative vehicles tested in the E-77, E-77-2 and E-77-2b programs that were operated 

on the four fuels used in this (2c) study.

Discussion of Test Results

While this assignment (E-77-2c) involved only permeation performance on two E20 fuels, 

additional value of this E-77-2c data is realized when the results are viewed in the context of the 

prior CRC work. There may be misleading conclusions when comparing data across fuels where 

a different number of vehicles contribute to the bars within a technology group. Drawing 

inferences in fuel effects based on these averages is inappropriate because individual vehicle 

effects come into play. 

There are three sections in the “Discussion” portion of this report: 

The permeation performance of the “Combined E-77 Fleet” on the various fuels (Task 

4.5 plus prior work). 

The additional leak testing that was done in this project, combined with the prior work to 

overview the effect of leak location. It also points out that the later vehicles with ORVR 

systems had different leak effects. (Task 4.7 plus prior work)

Description and details of the evaporative emission speciation measurements, and the 

methodology of the “Average Reactivity” calculations that were made. 

The actual test summaries and the plots of the results of each of the test vehicles on the two 

volatilities of the E20 fuel are contained in the Appendices, starting at page 38.

Note 1 - Vehicle 202 was found to have fuel injector leaks, 'O' ring leaks and a fuel neck leak. Repairs were attempted, and the 

vehicle was renamed 216 and the test sequence was repeated. The data generated was deemed questionable and was not 

used in this analysis.

Note 2 - Vehicle 207 was retested as 207L with an implanted 0.020" diameter leak in the fuel cap, and was tested on the 7 and

10 psi E10 fuels. For the E77-2c program, it was tested as 207c, with implanted 0.020" leaks seperatly at the tank top and at 

the canister inlet. During the static tests the tank was not pressurized because of the implanted leak. This data was

inappropriate for inclusion in this analysis.

Note 3 - Vehicle 220b exhibited a leak that was later determined to be a deteriorating crack in the fuel vapor vent elbow on the

fuel tank sending unit. The vehicle was dropped from further testing.

Note 4 - Vehicle 221 appeared to have a leak as indicated by the high permeation when the fuel tank was pressurized and 

when the fuel pump was energized.

Permeation Rate Relationships at 86o and 105oF - The relationship between the static 

permeation rates measured at 86oF and 105oF have been previously shown to generally follow a 

relationship of 105oF = 2 x 86oF11. This is usually stated as the relationship that follows a 

doubling of the permeation rate for each 10oC (18oF) temperature increase. The data measured 

during this program is plotted in Figure 7 below, with a 2:1 reference line added.

Running Loss and Hot Soak Performance - Permeation rate comparisons are shown below in 

Figures 8 and 9 for the running loss and hot soak measurements for the composite fleet, with 

permeation trends similar to the diurnal and static results. The units for the running loss 

measurements are expressed in time units, mg/hour, which the authors feel are more appropriate 

than the regulatory units of grams per mile. The conversion back to grams per mile could be 

made by multiplying by 48/60 to get the mass per test, and dividing by 20 to get the miles 

traveled (2 x 10 miles per LA92).

Note 3 - Vehicle 220b exhibited a leak that was later determined to be a deteriorating crack in the fuel vapor vent elbow on

the fuel tank sending unit. The vehicle was dropped from further testing.

Note 1 - Vehicle 202 was found to have fuel injector leaks, 'O' ring leaks and a fuel neck leak. Repairs were attempted, and

the vehicle was renamed 216 and the test sequence was repeated. The data generated was deemed questionable

and was not used in this analysis.

Diurnal Emissions Performance - Figure 10 shows the Day One diurnal emission results for 

the E-77 composite fleet, segregated by ethanol level, fuel vapor pressure, and vehicle 

technology group. The “Day One” performance is presented here because it includes the 

maximum number of tests to include in the averages – the earlier Pilot Study program did not 

include three-day diurnal evaluations. The cumulative diurnal performance for the three-day 

diurnal test is presented in Figure 11 with slightly fewer tests, but a similar permeation 

performance pattern. 

Starting at the left edge of Figure 10, there are two bars representing the average permeation 

measured for the 24-hour (or the first 24 hours of a longer test) diurnal test (1-day) with the 7 psi 

E0 fuel. The left blue bar represents the average for the nine Tier 1 vehicles that have been 

tested in the E-77 programs. The six newer Tier 2 vehicles’ permeation average is shown with 

the green bar. While the number of observations is small, it indicates that, on average, the newer 

vehicles have lower permeation on the 7 psi E0 fuel.

A similar trend is indicated in the second pair of bars, showing the permeation performance of 

the E-77 vehicles tested with the higher vapor pressure (9 psi) E0 fuel. The nine Tier 1 vehicles’ 

average indicated an increase in permeation with the higher vapor pressure fuel. The third and 

fourth pairs of bars in the figure show the results when the vehicles were tested with an E10 fuel. 

The permeation of the Tier 1 vehicles increased on average with the E10 fuels compared to the 

ethanol free (E0) test fuels. For the newer Tier 2 vehicles, the average permeation was not 

markedly different when comparing the E10 to the E0 results.

The performance of the vehicles with the E20 fuels is represented by the right two pairs of bars. 

Addressing first the Tier 1 vehicles, it appears that the permeation is higher with the E20 fuel 

than the E0, but lower with E20 compared to E10. The Tier 2 vehicles do not indicate a marked 

increase or difference with the E10 or E20 fuels, although the numeric values are higher.

Similar observations are made when the data for the cumulative three-day diurnal permeation 

emissions are charted in a similar fashion, as shown in Figure 11, below. In Figure 11, it should 

be noted that the 10 psi E10 averages for the Tier 1 vehicles are highly driven by the results for 

206(b), and the results for the Tier 2 vehicles are highly driven by the results for vehicle 214.

leaks seperatly at the tank top and at the canister inlet. This data was inappropriate for inclusion in this analysis.

Note 3 - Vehicle 220b exhibited a leak that was later determined to be a deteriorating crack in the fuel vapor vent 

elbow on the fuel tank sending unit. The vehicle was dropped from further testing.

Summary of Task 4.5

While the sample sizes are still too small to make comparison with statistical significance, 

several trends are suggested. Referring to the figures shown above, comparing the average 

permeation performance for various groups, the following trends and observations are offered:

1. The newer Tier 2 vehicles have lower permeation than Tier 1 on all fuels.

2. Permeation is higher with E10 or E20 compared to an ethanol-free (E0) fuel.

3. Permeation is lower with E20 compared to E10 on the Tier 1 vehicles, but the presence of 

a reduction is less clear for the newer Tier 2 vehicles based on the few tests available for 

analysis. Further research may be needed to determine the sensitivity of newer vehicle 

technologies to fuel effects.

4. Higher average permeation emissions may be associated with increased fuel vapor 

pressure for the Tier 1 vehicles tested in this program, but the average permeation 

emissions for the newer Tier 2 test vehicles show no clear trend with vapor pressure.

Task 4.7 - Effect of Leak Location on Permeation Emissions

For the last four decades12, vehicles sold in the United States have been equipped with 

evaporative emission control (evap) systems that are remarkably effective in reducing fuel 

evaporative emissions from automotive fuel systems. Light Duty Vehicles (LDV) starting in 

model year 1998 even control refueling emission to a very high degree. The performance of 

these evap systems are, however, affected by leaks that may exist in the fuel system of a vehicle. 

These leaks can be the result of, among other things, poor connections, scratched or misaligned 

seals, loose fuel caps, and improper maintenance, such as improper repairs done to other fuel 

system components that could result in leaks. Undetected (and un-repaired) leaks in automotive 

fuel systems can be a potentially significant source of vehicle emissions. 

This source of emissions (leaks) was addressed by regulation starting in MY 1998 with the 

implementation of onboard detection of fuel system leaks (OBD and a later OBDII). Current 

OBDII systems are capable of detecting vapor leaks of 0.020” diameter-equivalent or larger 

equivalent diameter, and alerting the operator to bring the vehicle in for service. As a result, 

leaks of this scale (if corrected) can become a much smaller contributor to vehicle fuel 

emissions.

Leaks with Pre-Enhanced, Pre-ORVR Systems - There is a need to understand the frequency 

and nature of leaks that may still exist in the inventory. The Coordinating Research Council 

(CRC) sponsored test programs (E-77, E-77-2) in recent periods that were designed to measure 

emissions from implanted 0.020” diameter leaks located in the gas cap in several test vehicles. 

The test vehicles were subjected to a series of emission tests, including a summertime (65° to 

105° F) diurnal event.

In the initial test program (CRC E-77), a 1996 Cavalier with Enhanced Evap control hardware 

was selected as the test vehicle. The Cavalier was equipped with a simple tank venting system 

(Figure 12) with an inline 0.055” orifice in the vent line from the tank and leading forward to the 

canister. Because of the flow restrictions caused by the 0.055” orifice, the length of the vent 

 

12

 The first federal requirement for fuel evaporative emission control was model year 1971. California required 

systems a year earlier (1970)

line, the multiple bends, and the carbon bed in the canister, the 0.020” leak implanted in the cap 

provided a convenient, parallel path to the atmosphere. With an implanted leak in the fuel cap, 

about 21 grams of HC were emitted into the SHED (Table 11) during the diurnal test with E0 

fuel, while the baseline test with no leak resulted in only 0.4 grams of diurnal emissions. It was 

estimated, using contemporary vapor generation models, that the uncontrolled vapor emissions 

from this test13 would have been 23.2 grams if the cap had been left off completely. The 20.7 

gram emissions level corresponds to a 89% loss to the environment.

Discussions about this test result created the realization that the location of the leak, and the 

configuration of the vehicle’s fuel system, would probably have a significant effect on the 

resulting emissions. Even though the leak in the fuel cap was smaller than the 0.055” orifice in 

the tank vapor line, most of the HC vapors passed through the leak to the atmosphere because it 

was a path of relatively low resistance.

Leaks at the Fuel Cap with ORVR Systems - In a subsequent test program (E-77-2), a similar 

diurnal test was conducted on a 2001 Dodge Caravan (Fig. 13) and a 2004 Toyota Camry (Fig.

14) using E10 fuel. Both vehicles were equipped with Onboard Refueling Vapor Recovery 

(ORVR) systems as well as OBDII and Tier 1 Evap. A 0.020” leak was implanted in the fuel 

cap of each vehicle and the resulting SHED emissions are shown in Table 6. The resulting net 

increases in emissions were 1 gram for the Caravan and 0.4 grams for the Camry, much lower 

than the results measured during the evaluation of the Cavalier.

The following discussion attempts to explain the hardware and component differences that 

contributed to the different results.

(The use of E10 test fuel should not have a significant effect on diurnal emissions)

There is an important difference in the configurations of these two vehicles compared to the 

Cavalier that contributed to the low effect of leak implantation on diurnal permeation emissions. 

An Inlet Check Valve (ICV) is located in the fill pipe of the Dodge Caravan (item 11 on Figure 

13) at the entrance to the tank. The ICV is a common component in ORVR systems and is 

designed to prevent spitback from the fuel tank during a refueling event. During the diurnal tests 

on the Caravan, the ICV seal prevented HC vapors from taking a direct communication path up 

the fill pipe and thus into the SHED. There is a path from the top of the tank’s vapor space that 

communicates with the area near the fuel cap, (shown as item 2, a “recirculation tube.” in Figure 

13) but this appears to be a less attractive path compared to the refueling vapor path to the 

canister.

The Camry system shown in Figure 14 is more complex than the Caravan, as the Toyota system 

uses a “vent switching” configuration during refueling events. 

In each of the test vehicles, the only flow path from the tank vapor space to the cap is through the 

vapor recirculation line shown in Figures 13 and 14. This line contains an orifice; the 

accompanying restrictions offered by the tubes and turns in the flow path to the cap significantly 

reduced the emissions from the implanted leak. The more open path for vapors is through the 

large refueling vent to the low restriction carbon canister. This effect could also be a result of 

the cap ”seeing” an effective vapor space volume equivalent to the volume of the filler neck. 

Assuming a 2ft, 2” diameter filler neck, this could amount to 1⁄2 gallon of vapor space. Scaling 

the uncontrolled result of 23.2 grams by the Cavalier vapor space vs. 1⁄2 gallon results in a diurnal 

emission rate of about 1 gram.

Alternative Implanted Leak Locations - In order to evaluate the effect of other leak locations 

and system configurations on the emissions from small leaks, a test plan was included in E-77-2c 

that expanded on the data already observed from the tests with leaks implanted in the cap. In this 

test series, a 0.020 leak was implanted separately in two new locations, in or near the top of the 

tank, and at the vent line hose connecting to the canister. The test vehicles were the same 2002 

Dodge Caravan and 2004 Toyota Camry used in the previous testing. The previous data from 

these vehicles were then compared to the data for the two new leak locations to add to the 

understanding of the impact of small leaks on emissions.

For the Task 4.7 assignment, the laboratory staff placed (implanted) a 0.020 inch internal 

diameter hole at various places in the vehicle’s fuel system. Carburetor jets of the 0.020 inch

internal diameter size were purchased from a local source, fixed into a small disc, clamped into a 

stainless compression fitting and screwed into the desired position. 

Previous tests had been performed with a similar size “leak” in the vehicle’s fuel cap. The 0.020 

inch diameter hole was placed in two different locations on each vehicle:

1. at the top of the fuel tank in the tank sending unit cover, and 

2. at the connection to the canister inlet from the fuel tank.

Leak Location at the Top of the Tank - Figure 15 shows the fitting in the Caravan (207) cover 

with a red arrow pointing to the position of the 

“leak”. This was sealed when the leak was 

moved to the canister inlet.

Similarly, Figure 16 shows the fitting in position 

on the Toyota Camry tank.

cap” leak are from the previous test programs. The green and blue traces show a small effect of 

the leak, while the leak implanted in the top of the tank (red trace), and at the canister inlet (gold 

trace) show a much larger effect (compared to the “no-leak” condition).

Summary of Task 4.7

The tests performed for Task 4.7 demonstrated two findings that may have significance for air 

quality modelers:

Vehicles fitted with ORVR systems may have changed the emission impact of a small 

leak at the fuel cap. Leaks added at the fuel cap for the two ORVR vehicles tested 

produced one day diurnal emissions almost an order of magnitude lower than was seen 

with a previously tested non-ORVR Cavalier. This change in the emissions measured is 

thought to be due to the addition of “check valves,” or “anti-spitback valves” added to the 

systems to improve the fuel fill control.

Diurnal emissions measured with leaks implanted at the top of the fuel tank, or at the 

entry to the carbon canister, were significantly higher than the emissions with a leak 

implanted at the fuel cap on the two ORVR-equipped vehicles tested. While it was 

expected that the permeation emissions from a leak at the top of the tank might be higher 

than those from a leak at the fuel cap, a similar difference in emissions between an 

implanted leak at the canister inlet versus one at the fuel cap was not. 

Speciation of the Permeation Results

The E-77-2c scope of work request included gas chromatographic speciation of all the vehicle 

tests, including the static tests, the dynamic, and the diurnals on both fuel volatilities. This 

generated a sizable file of test results. The detailed speciation summaries are presented at the 

end of this report in Appendix II. The implanted leak tests on Vehicles 207 and 211 (Task 4.7) 

were also speciated, but must be analyzed separately from the Task 4.5 results, as the analysis 

contains not only the vehicle’s permeation, but the vapor from the induced leak. The next few 

pages will be used to explain the project’s file structure, and the calculations used to speciate and 

calculate the reactivity of the various tests. 

Basic Speciation File Example - Table 13 is a truncated example of the basic speciation file that 

is generated by the laboratory (ATL). While it has been cut off after elution number 26, there are 

172 species in the total report, plus methanol, ethanol and R-134a (refrigerant)14. This selected 

file exists as one of the tabs in the project data file set identified as “206cgc.xls.” This example 

summarizes the results for the 72-hour diurnal results on vehicle 206c – Test number 7703. For 

the 72-hour test, sample bags of the VT-SHED are collected at the start of the diurnal (T0), at 24 

hours (T24), at 48 hours (T48), and finally at 72 hours (T72). In this example, the results are 

summarized for the composite 72-hour test.

 

14

 Stating again, the permeation performance values used in this report have corrected the FID’s misidentification 

of the ethanol molecule, and the identified non-fuel components, methanol and refrigerant (R-134a), have been 

subtracted from the totals. 
Final CRC E-77-2c Report - Dec 2010

Table 13

Speciation File Example

The file is organized in the following fashion: Column 1 is the elution number, Column 

2 is the species name and Column 3 is the CAS Number (with leading zeros as necessary 

to maintain a 10 digit format). The CAS number is a unique number created and 

maintained by the CAS Registry®(http://www.cas.org) that provides a name and property 

resource for recognized substances. 

The right hand four columns in the figure are the test results. The EXCELTM file contains six or 

more digits of precision, but the precision in the figure has been reduced for clarity. The net 

concentration in ppmC is calculated by subtracting (for each species) the start of test 

concentrations (T0) from the 72-hour results, yielding the net increase in concentration for the 

three-day period. One could obtain the speciation results for the third day, for example, by 

subtracting the concentrations at T48 from the T72 measurement. The net mass for each of the 

species is calculated by using appropriate volume, concentration and density values. The last 

two columns are the relative contribution (% of total present) of the species to the total of all the 

concentrations measured.

listing the species by decreasing mass in the sample. The blue arrow in the middle of the figure 

indicates where lines of data were eliminated from the table, to keep the figure to a convenient 

height. In the figure above, and typical for the E20 test results, the ethanol species has the 

highest mass in the sample, and thus appears as the first data line. The next largest mass is the 

isopentane, and so on. The next column lists the MIR value for that species. The Maximum 

Incremental Reactivity scale (MIR) scale15 created by William Carter, and adopted by CARB, 

has been used to estimate the equivalent ozone that would be produced by the various species 

found in this measurement. The report listed in the footnote contains the following quote:

The methods and procedure used to derive the MIR scale presented in this report are

comprehensively documented by Carter (2009a) and references therein, and those reports 

should be consulted for details. Briefly, the reactivity scale is based on calculations of relative 

ozone impacts, expressed as mass of additional ozone formed per mass VOC added to the 

emissions, for various compounds under various atmospheric conditions, given a chemical 

mechanism for the compounds and other relevant atmospheric species, models for various 

atmospheric conditions, and a modeling and reactivity assessment procedure. The methods, 

atmospheric scenarios, and modeling and reactivity assessment procedures were the same as 

employed in previous calculations of the MIR scale (Carter, 1994a, 2000, 2003), and are 

based on those first developed by Carter (1994a,b), with a few modifications as described by 

Carter (2000). The only difference between this updated scale and the previous MIR scales of 

Carter (2000, 2003) concern the chemical mechanism used and the number and types of 

VOCs whose ozone impacts are calculated.

Multiplying the mass of the individual species by the MIR factor yields the last column, the mass 

of ozone that might be produced by that mass of speciate. The “average reactivity” of the sample 

is calculated (and shown at the bottom of each file) by summing up the speciated mass, and the 

estimated ozone mass, and dividing the total ozone value by the total VOC (fuel) mass. In this 

example, the average reactivity is 3.362 (in grams of ozone per gram of volatile organic 

compound).

Reactivity Comparison for Various Fuels and Test Sequences Table 15 offers a summary of 

the Vehicle 206c data measured and calculated using the E20 fuel. Similar summaries for the 

other vehicles appear with the data listings in the Appendix. Columns 4 and 6 compare the mass 

estimates by two different techniques. Column 4 is the mass estimate one would obtain using the 

SHED technique. Column 6 lists the gas chromatograph mass estimate. This technique 

accumulates the total mass in the sample from the sum of the individually identified molecules. 

The first line of data in the figure indicates good correlation, 168 mg versus 162. The second 

line indicates that the GC measured 17% more in the sample (column 5, GC as % of THC = 

116.9%), which is less than one would hope to see. Plus or minus 10% in readings is a goal the 

author would hope to achieve.

The last column (Species Present) indicates the number of species identified using the GC. 

Thirty (30) or more is an indication that there was a high enough level of permeation that the 

chromatograph identified. Other projects, where the permeation level is low (~30 mg) can give a 

much lower number of species identified.

Reactivity Comparison

Summary and Recommendations for Additional Investigations

There are several subjects that are recommended for additional investigation.

1. The Tier 2 (Near Zero) vehicles suggest that the effect of ethanol on permeation may be 

reduced (or zero?) based on the limited number of tests available to date. The indication 

may change if the Tier 2 vehicles are tested after they are five or more years old.

2. The Tier 2 vehicles also show a mixed effect of fuel vapor pressure on permeation. 

Permeation was higher in many cases with the lower vapor pressure (7 psi E20) fuel. The 

order of testing was always first on the 9 psi fuel, and then a week later on the 7 psi fuel. 

Should the order have been mixed? 

3. Is it possible that the newer advanced materials (tanks, hoses, seals) used in the Tier 2 

vehicles are more resistant to changes in permeation, and take longer to stabilize than 

previously thought?

Appendix III – Test Concept

The testing concept and procedures used in this program have evolved throughout the CRC E-77 

program series, and are included here for reference.

The E-77 Test Concept: Measuring Leaks, Permeation and Diurnal Vapor Losses 

CRC’s E-77 emission test programs have developed (and strive to continually improve) new 

methodologies for understanding and quantifying vehicle evaporative emission rates. The 

concept partitions and assigns the vehicle’s contribution to the evaporative emission inventory 

into three mechanisms:

1. Permeation

2. Tank vapor venting

3. Leaks (with two subsets - Liquid and Vapor)

Permeation is the migration of HC through the various elastomers in a vehicle fuel system16. 

Previous testing has shown that permeation rate is strongly affected by the material’s 

temperature, doubling for each 10oC (18oF) increase in the range of normal summer temperatures 

(See, among others, CRC E-65.3 report) It is also strongly affected by gasoline composition, 

especially with ethanol-containing fuels.

Tank vapor venting emissions are controlled by fitting a carbon canister to the atmospheric tank 

vent. Figure A1 is a schematic of a typical early control system. During a daily heating period, 

the temperature of the vehicle’s fuel tank increases, forcing HC vapors from the tank. Excess 

emissions, exceeding the carbon canister’s capacity, are vented to the atmosphere. 

Figure A-1. Control System Schematic

McClement, September 2004, available on the CRC and California Air Resources Board websites.

Leaks can be liquid or vapor. Mass emissions are measured in a VT SHED or Variable 

Temperature Sealed Housing for Evaporative 

Determination. The SHED test method combines all 

three emission mechanisms (leaks, diurnal venting, and 

permeation) into a single test result.

The SHED technique involves placing the vehicle in a 

sealed enclosure (Figure A2), and calculating the mass 

in the enclosure from the volume, density and 

concentration in the enclosure at the start and end of a 

time period. The difference between the mass at the 

start and end of test is the emission rate, e.g., grams per 

unit time. 

Permeation and tank venting losses are strongly 

driven by fuel composition, ambient temperature, and 

ambient temperature change. Liquid leaks are not 

strongly affected by normal summer temperatures, 

and are thought to have two components: 

1. Static leaks occurring while the engine is turned off and the vehicle is stationary 

2. Increase in leak rate caused by the system pressure increase during engine operation.

Each is described in detail below.

1. Static Permeation Testing

The constant temperature (static) permeation rate is measured in a traditional SHED (Constant 

temperature) in the following manner.

A. The fuel tank is drained and filled to 40% tank capacity with the test fuel.

B. The day before testing, the vehicle is driven over four road trips of 7.5 miles each to 

precondition the canister.17 (These drives are similar to the LA-4)

C. Upon return from the road pre-conditioning, the fuel tank is drained and filled to 40% 

tank capacity with the test fuel.18

D. Vehicle is parked for 18-22 hours in a controlled temperature environment at test 

temperature (86oF)

E. The vehicle is then moved (without starting) into the test (86oF) SHED

F. The canister vent is connected to the SHED bulkhead fitting which routes the vapor to 

the trap canister outside the SHED

G. The tank system pressurization hose is connected

H. The fuel pump electrical connection is connected

 

17

 This conditioning can be done in the laboratory on a chassis dynamometer if proper attention is paid to 

underbody cooling and unrepresentative fuel tank temperatures are avoided.

18

 Vehicles with ORVR systems will add the refueling vapors to the canister. This is OK.

Determination

I. The SHED is sealed, the inside temperature is allowed to stabilize and the test is started. 

Continuous total hydrocarbon (THC) measurements are made using a FID. Ethanol, 

methanol and R134a concentrations are measured using an INNOVA analyzer. All 

measurements are made at least every minute for one hour to determine the stabilized 

permeation rate.

J. At the end of the static test (60 minutes), the vehicle’s vapor system is pressurized to 5 

inches of water for thirty minutes. Measurements are made to quantify vapor leaks as 

determined by a change in the SHED uncorrected mass.

K. The fuel pump is then energized for 30 minutes while maintaining the 5 inches of water 

on the vapor system. Liquid leaks are quantified as determined by a change in the SHED 

concentrations.

The purpose of steps J and K above is to validate that the permeation rate measurement was 

made without the presence of any leak – either liquid or vapor.

2. Running Loss Test (Dynamic Test)

A. The vehicle is placed in the RL-SHED and prepared for test. (The fuel level and 

condition for the dynamic test is the fuel remaining after completion of the static test –

40% fresh fill of the appropriate test fuel)

B. Outside air source for the engine is connected

C. Vehicle exhaust is connected 

D. Fuel tank thermocouple is connected

E. Canister vent is connected to the SHED bulkhead fitting which routes the vapor to the 

trap canister outside the SHED

F. Vehicle is allowed to stabilize in the RL-SHED at test temperature (86°F) for a minimum 

of 12 hours – preferably overnight.

G. Two cycles of the Unified Cycle (LA-92) driving schedule (48 minutes.) are driven while 

measuring the mass emissions in the SHED. Vehicle is allowed to idle (in drive) for 30 

seconds between the two cycles. Ambient air temperature is maintained (to the extent 

possible) at 86°F. Fuel tank surface temperature is monitored during vehicle operation. It 

should increase during the drive from 10 to 18°F to simulate expected on-road 

temperature increase. Measured mass emissions are corrected using the INNOVA data 

for the ethanol, methanol and refrigerant emissions.

3. Hot Soak19

This procedure is executed immediately following the Running Loss Test procedure 

described above.

A. Engine is turned off, transmission selector is placed in park, and driver exits the 

enclosure, using the double door air lock, taking care to minimize any air exchange 

between the laboratory and the SHED. This starts the one hour “hot soak” period.

 

19

 Our definition is that the “hot soak” is the temporary increase in emission rate caused by the vehicle’s 

immediately preceding operation. It is the increase in the SHED mass (corrected for EtOH, MeOH and R-134a) 

over the one hour period minus the previously established “static” permeation rate.
Final CRC E-77-2c Report - Dec 2010

72

B. Measurement of mass emissions in the SHED are continued for another 60 minutes (until 

time = 108 minutes), correcting for the ethanol, methanol and refrigerant mass using the 

INNOVA instrument data. This ends the hot soak. Hot soak emissions are calculated as 

the net difference for the one hour hot soak (CorrMass108 – CorrMass48 minus the 86°F 

static hourly rate, all mass rates in mg/hour). 

4. Diurnal Test

A. The fuel tank is drained and filled to 40% tank capacity with the test fuel.

B. The day before testing, the vehicle is to be driven over four road trips of 7.5 miles each to 

precondition the vehicle and the canister.

C. Upon return from the road pre-conditioning, the fuel tank is drained and filled to 40% 

tank capacity with the test fuel.

D. The vehicle is parked for 18-22 hours in a controlled temperature environment at the 

initial diurnal test temperature (65oF).

E. The SHED is sealed, allowed to stabilize at the 65°F temperature and the 3-day 

California Diurnal Test is started. 

F. “Continuous” (every 30 seconds) total hydrocarbon (THC) measurements are made using 

a FID. Ethanol, methanol and R134a (refrigerant) concentrations are measured using an 

INNOVA analyzer, at least every 10 minutes for the duration of the test (72 hours).

Static Permeation Test – Leak Validation 

If a leak is detected during either the vapor system pressure portion (Step J) or the pump 

energized portion (Step K) of the Static Permeation Test procedure, it calls into question whether 

the permeation rate measurement accurately reflects fuel system permeation or if instead a 

combination of permeation and the implied leak was measured. If a leak is confirmed, the 

permeation rate measurement is called into question, and an investigation, possible remedy, and 

retest is indicated.

The permeation rate measurement must be corrected for the FID’s ethanol misrepresentation, and 

the presence of non-fuel hydrocarbons (methanol and refrigerant). The leak check however, is 

made using the change in mass increase in the SHED using the uncorrected FID mass calculation 

as the determinate. We found that the corrections for ethanol, methanol and refrigerant were 

introducing “noise” into the trace that we were misinterpreting as leak(s). 
Final CRC E-77-2c Report - Dec 2010

73

Figure A-3 represents the calculations made during the inspection of data from a successful test. 

EXCEL’s©“SLOPE” function is used to calculate the linear regression values based on the FID 

calculation for mass for: Time 0 to 60 minutes, Time 64 to 90 minutes, and Time 94 to 120 

minutes. A 4 minute gap was included between each sequence to establish the new mass 

emission rate during the “pressure on,” (T60 to T90), and the “pump energized” periods.

The slope of 70.6 mg/hr for the “Tank Pressurized” period in the example above is compared to 

the slope of 70.5 mg/hr calculated for the permeation rate (or hot soak) period. If the “Tank 

Pressurized” slope is not more than 10% higher than the 0 to 60 minute permeation rate, we 

assume that there is no leak present. A similar comparison is made for the slope determined 

during the “pump on” period. The choice of a 10% allowance is arbitrary and is used here to 

allow for normal and unavoidable test variation.

For tests in which the above procedure determines that no leak is present, a value of zero is 

reported in the test summary for the leak results. If a positive value is reported, it calls that test 

into question, and an investigation, possible repair, and retest is indicated.

Static Permeation Rate Determination

The static permeation rate is determined based on a linear regression through the individual 

corrected fuel data points (30 second data) for the first 60 minutes of testing as illustrated by the 

corrected FID data shown in the red trace in Figure A-3 above; in this case 72.1 mg/hour.

Dynamic (Running Loss) and Hot Soak Test

The preceding section addressed the concepts of separating the permeation emissions from the 

tank venting emissions, and establishing the presence or absence of leaks. The second part of 

this study includes a dynamic test to measure the permeation and tank venting emissions during 

vehicle operation (“running losses”) and the temporary condition following vehicle operation 

known as the “hot soak.”

This is considered a “dynamic” test because the vehicle is driven and the fuel and vapor system 

temperatures rise during the test. The ambient temperature in the Running Loss SHED during 

test was held constant at 86°F, while the vehicle’s fuel system temperature rose during the test. 

Two 1435 second (23.9-minute) LA-92 driving cycles were performed consecutively during the 

running loss measurements with a 30 second idle in-between. During this test, tank fuel 

temperature was expected to rise by an average approximately 18°F above the initial ambient 

temperature. The running loss air handling system included a proportional speed under-car 

blower operated as a slave to dynamometer speed. This apparatus was used during running loss 

testing with minor tuning for specific vehicles. It is, without additional input, capable of 

reasonable fuel tank temperature control. Each vehicle was fitted with a surface-mount 

thermocouple at the front of the fuel tank, located at approximately the 1/8th fill level to measure 

the fuel liquid temperature. No attempt was made to follow a predefined fuel tank temperature 

profile (FTTP) in this program. Fuel temperatures were recorded, and results are available in the 

real-time records.

Vehicle running loss emissions are measured in a special version of a SHED known as a 

Running Loss SHED (RL-SHED)20, shown in Figure A-4. Special features of the RL-SHED 

include a sealed chassis dynamometer for simulating vehicle driving loads, a sealed outside air 

supply for engine intake, a sealed exhaust conduit for engine exhaust, and an under-chassis fan 

for simulating underbody air flow as described above. A vehicle is operated inside the RL-SHED 

over a chosen driving cycle. The increase in HC emissions inside the enclosure are measured 

and calculated as mass emissions per 40 CFR §86.163-96. Vehicle testing in an RL-SHED is 

complicated by several factors, including:

1. The engine must be supplied with external induction air.

2. The exhaust must be conducted externally without any leaks.

3. The load supplied to the vehicle through the chassis dynamometer must not create or 

allow external leaks.

4. The internal SHED temperature must be maintained while sizable heat is rejected to 

the ambient by the running engine and exhaust.

5. The cooling air supplied to the radiator must be modulated to represent the vehicle’s 

road speed.

6. The underbody (and especially the fuel system) temperature should represent the rate 

of rise experienced by a real road-drive.

Canister vent losses were isolated from permeation emissions using the technique described 

previously. The vehicle’s carbon canister fresh air vent was connected to the outside of the RLSHED using a leak-tight Teflon®

hose connected to a small carbon “trap” canister located on a

top-loading precision scale outside the SHED. The scale precision was 0.01 grams (10 

milligrams). There were no tank venting emissions measured on any of the running loss test 

measurements. All of the vehicles appeared to be actively “purging” the vehicle’s control 

canister and drawing fresh air during the test. If there were any emissions from the vehicle’s 

canister, as might have occurred if there were no vehicle purge or if very high volatility fuels 

with excessive vapor generation were used, it would have been measured.

The Running Loss Driving Cycle consisted of two cycles of the “Unified Driving Cycle,” otherwise 

known as the LA-92. A velocity versus time plot for one cycle is shown in Figure A-5.

The LA-92 cycle takes 24 minutes to complete, and covers 9.8 miles, with many speed changes. 

Two back-to-back cycles were driven, the first as a “cold start,” and the second following a 30 

second vehicle idle. The “cold start” condition was created by soaking the vehicle for a 

minimum of 18 hours at 86°F, moving it to the stabilized 86°F RL-SHED, making the test 

connections, and then waiting a minimum of one hour before the initial start and run.

The SHED emissions were measured during the 48 minutes of engine operation, and then 

continuously for one hour after the engine was turned off. This one hour, engine-off duration 

was the “hot soak” period. The total test time is 1 hour and 48 minutes.

Figure A-6 shows results from the 9 psi E20 fuel test on Vehicle 209c. The horizontal axis is test 

time in minutes, and the vertical axis is the HC mass measured in the RL-SHED during the test 

period. 

The engine was shut off at the end of the second LA92 drive cycle (~48 minutes), and the 

analysis system continued to measure the HC emissions in the SHED for the next 60 minutes. 

This represented the “hot soak” portion of the test.

The “True” Hot Soak

The traditional hot soak is determined from the increase in SHED emissions as measured for one 

hour following a prescribed drive to heat up the vehicle (2 LA-92 cycles during the Running 

Loss Test). Hot soak emissions, however, have two components; one that is caused by the 

elevated temperature resulting from the drive, and another that results from one hour of static 

permeation.

To separate these two components and determine the “true” hot soak emissions, the following 

procedure was used. “Traditional” hot soak emissions were first calculated by subtracting the 

“start of hot soak” cumulative SHED hydrocarbon value (i.e., 293.6 mg @ t = 48 minutes) from 

the final cumulative SHED hydrocarbon value (i.e., 379.3 mg @ t = 108 min.). This resulted in a 

cumulative SHED hydrocarbon value of 85.7 mg for the one hour hot soak. The previously 

determined 86oF static permeation value (i.e., 42.0 mg/hr) was then subtracted to arrive at the 

“true” hot soak value of 43.7 mg. 

In Figure A-6, the static permeation rate is superimposed as a solid blue line on the plot from the 

starting point of the hot soak until its end (one hour). While the “traditional” hot soak would be 

calculated as 85.7 mg, the “true” hot soak is determined as 43.7 mg. True hot soak values 

reported here were determined in this manner.

Diurnal Test

Diurnal permeation was determined by subjecting the vehicle to a three-day period in a 

temperature controlled SHED while recording the total hydrocarbon every 30 seconds. The 

SHED environmental temperature was varied from 65°F to 105°F per the California Diurnal Test 

protocol. Canister vent losses were isolated from permeation emissions using the technique 

described previously. The vehicle’s carbon canister fresh air vent was connected to the outside 

of the RL-SHED using a leak-tight Teflon®hose connected to a small (1 L) carbon “trap” 

canister located on a top-loading precision scale. The scale precision was 0.01 grams (10 

milligrams). 

ATL’s Speciation Method

ATL has developed a hydrocarbon speciation method that is functionally equivalent to the dualGC AQIRP method. The AQIRP, or “Auto/Oil Program,” test method was first documented in 

two SAE papers:

1. SAE 920320, Advanced Emission Speciation Methodologies for the Auto/Oil Air Quality 

Improvement Research Program -I. Hydrocarbons and Ethers; and 

2. SAE 920321, Advanced Emissions Speciation Methodologies for the Auto/Oil Air 

Quality Improvement Research Program – II. Aldehydes, Ketones, and Alcohols

A later update to the HC and Oxygenates procedures was published as:

SAE 930142, Improved Emissions Speciations Methodology for Phase II of the Auto/Oil 

Air Quality Improvement Program Hydrocarbons and Oxygenates

(See also, for reference, ARB’s SOP NO. MLD 115, “Procedure for the Determination of Ethers 

and Alcohols in Gasoline by Gas Chromatography”, January 2003, and SOP NO. MLD 118, 

“Procedures for the Detailed Hydrocarbon Analysis of Gasolines by Single Column High 

Efficiency (Capillary) Column Gas Chromatography”, August 1997) 

Instrumentation demands are simplified, and overall analysis time is shortened; yet high 

resolution and sensitivity are still achieved. In this single-GC/dual column method, all 

components are separated using on column type and temperature program. Analysis time for a 

cycle is 65 minutes. Each exhaust or evaporative gas sample is simultaneously injected (using a 

single sampling from the bag) into two identical columns present in the GC. A Varian Model 

3400 GC is used for hydrocarbon (HC) analysis. The GC is equipped with a dual temperaturecontrolled Valco 6-port valve injector; dual flame ionization detectors (FID), and dual 60 meter x 

0.32-mm ID fused silica capillary columns with 1.0μ polydimethylsiloxane stationary phase 

(J&W DB-1). One of the injectors uses an 85 μL sampling loop for low sensitivity analysis of 

C1-C12 while the other injector either uses a 1000 μL loop for high sensitivity analysis of C4-C12

(for simultaneous low/high sensitivity analysis of a single bag sample). Column A contains a 

85μl sample loop (splitless injection) that provides an injection volume that is small enough to 

allow resolution of the C1 through C4 hydrocarbons while large enough to retain the highest 

sensitivity possible. Column B receives a 1000μl splitless injection, providing higher sensitivity 

for components eluting after isobutane. Quantitative comparison of two overlap components

(butane and isopentane) provides a quality control measure. Data from Column A is used to 

detect and quantitate the 12 earliest eluting hydrocarbons with detection limits of 15-25 ppbvC 

corresponding to 0.2-0.3 mg/mi hydrocarbon for FTP stages 1 and 3, and 0.3-0.5 mg/mi for FTP 

stage 2. Data from Column B gives detection limits 0.017-0.04 mg/mi HC for components 

eluting after isopentane (18th in elution order). The components eluting between the 9th and 18th

in elution order have detection limits ranging between the levels listed above for each column.

The advantage of this approach is that, even for relatively clean vehicles, essentially all of the 

first 12 species are typically present at levels exceeding the Column A detection limit. Those 

speciated components that are below the first column detection limit tend to be in the molecular 

weight range best suited for the 1000μl injection analysis, which provides the limits 0.017-0.04 

mg/mi HC for components eluting after isopentane (18th in elution order), where additional 

sensitivity is needed. In previous work that applied this analysis approach, detection limits were 

determined to be between 0.02-0.06 mg/mi for the toxics 1,3-butadiene and benzene.

ATL’s hydrocarbon method uses Varian 3600 GCs with dual injectors, columns, and flame 

ionization detectors, allowing two similar analyses to be run simultaneously, as mentioned 

above. A Varian Star PC-based (using Microsoft WindowsTM) data system is used for data 

acquisition. Custom-made software is used for peak identification and converting data into a 

Microsoft ExcelTM spreadsheet format. A comparison of the total hydrocarbon determined using 

the GC versus the CVS (“speciation recovery”) is used as a quality control measure, and ATL 

routinely achieves hydrocarbon speciation recoveries ranging from 93% to 105% for lower 

emitting vehicles. A 23 hydrocarbon component standard mixture is analyzed at the start of each 

day on each GC to provide quantifying coefficients and a quality control check on daily 

reproducibility of instrument performance.
