Notice: 

Environmental Protection Agency 

In an attempt to make these notations easier for agencies to enter into 

their databases, JCAR is going to try out sending a mark-up of the 1st 

Notice version instead of a description of the change. If this does not 

prove to be easier for you, please call Rita Messinger at 5-22.54 by the 

end of June to express your preference for the old system, or if you have 

any suggestions of ways to make a mark-up more helpful. If a sufficient 

number of agencies express a preference for the status quo, we will 

return to the line numbered description of the change in July. 

On this mark-up, any word or punctuation that bas been altered will be 

highlighted. You will need to compare this to your hard copy or your 

database to determine how the original text read. If a white space 1s 

highlighted, you will know that text has been omitted at that location. 

As always, if you would like an adopted rulemaking on disk for 

purposes of upload, contact Terra Lamb at 5-2254.

~ Steady-State Idle Exhaust Test 

To prevent excess dilution in a steady-state idle exhaust 

emissions test described in Section 276.204, the sample . probe 

shall be inserted a m1n1mum of 10 inches into the vehicle's 

tailpipe. Extension boots shall be utilized if it is impossible 

to insert the sample probe at least 10 inches into the tailpipe. 

A vehicle emission test shall be invalid if the applicable 

emission standards contained in 35 Ill. Adm. Code 240 are met but 

the sum of the CO and C0[2) concentrations in the exhaust gas does 

not exceed 6 percent during the sample averaging period(s). 

Q1 Transient Loaded Mode Exhaust Test 

To prevent excess dilution in a transient loaded mode exhaust 

emissions test described in Section 276.207, the exhaust 

collection system shall be positioned to insure complete capture 

of the entire exhaust stream from the tailpipe during the 

transient driving cycle. The test system shall verify that the 

entire exhaust stream is being collected through continuous 

monitoring of exhaust C0[2] generated during the transient driving 

cycle and comparison with theoretical levels of exhaust C0[2) 

produced by the vehicle being tested. A vehicle emission test 

shall be invalid if the measured values fall below expected values 

during the transient driving cycle. At a m1n1mum, the emission 

test shall be invalid if five consecutive one-second average C0[21 

values fall below 0.085 percent during seconds 5 through 220 of 

the transient driving cycle.

a) General Requirements 

1) The test shall consist of up to 240 seconds of mass emission 

measurement using a constant volume sampler while the vehicle 

is driven through a computer-monitored driving cycle on a 

dynamometer with inertia weight settings appropriate for the 

weight of the vehicle. The driving cycle shall include 

acceleration, deceleration, and idle operating modes as 

specified in subsection (e)(l) of this Section. The 

240-second sequence may be ended earlier using fast pass 

algorithms. 

2) The emission standards and dynamometer inertia and power 

absorption settings shall be automatically selected for the 

vehicle being tested based upon the identification and 

validation of the following, as needed: 

A) Vehicle type: LDV, LDTl, LDT2, and others as needed; 

B) GVWR; 

C) Chassis model year; 

D) Make; 

E) Model; 

F) Number of cylinders; 

G) Transmission type; 

H) LVW or ALVW; and 

I) Engine displacement. 

Alternative computerized methods of selecting dynamometer 

test conditions, such as VIN decoding, may be used. 

3) The ambient temperature, absolute humidity, and barometric 

pressure shall be recorded continuously during the transient 

test, or as a single set of readings if taken less than 4 

minutes prior to the transient driving cycle. 

4) If the vehicle is shut off, the vehicle shall be restarted as 

soon as possible before the test and shall be running for at 

least 30 seconds prior to the transient driving cycle begins. 

5) If a vehicle stalls during a transient test, the test shall 

be aborted and restarted. If after 3 attempts the test 

cannot be completed, the vehicle shall be rejected. 

b) Pre-inspection and Preparation 

1) Initial tests (i.e., those occurring for the first time in a 

vehicle's scheduled test cycle) shall be performed without 

repair or adjustment at the inspection facility prior to the 

test. 

2) A test, once initiated, shall be performed in its entirety 

regardless of intermediate outcomes, except in the case of 

invalid test conditions or unsafe conditions. 

3) Tests involving measurement shall be performed with 

Agency-approved equipment that is operated in accordance with 

the procedures contained · in 40 CFR 85.2234 (Draft), 

incorporated by reference in Section 276.104(a) of this Part. 

4) All accessories (air conditioning, heat, defogger, radio,

6) Vehicles with missing tailpipe sections that prohibit 

placement of the exhaust collection system to capture the 

entire exhaust stream shall be rejected from testing. 

7) The vehicle temperature gauge, if equipped and operating, 

shall be checked to assess temperature. If the temperature 

gauge indicates that the engine is well below normal 

operating temperature, the vehicle shall receive a 

second-chance emission test if it fails the initial test for 

HC or CO. Vehicles in overheated condition shall be rejected 

from testing. 

8) Vehicles shall be rejected from testing if drive axle tires: 

A) exhibit visible cords, belts, bubbles, cuts, or other 

damage, or 

B) are space-saver spare tires, or 

C) are not reasonably sized tires. 

9) Vehicles' drive axle tires shall be inspected for proper 

inflation. If one or more of these tires appears low, it 

shall be inflated to approximately 30 psi, or to tire 

sidewall pressure, or manufacturer's recommendation. 

10) Drive axle tires of vehicles subject to additional testing 

for the purpose of program evaluation under 40 CFR 51.353, 

incorporated by reference in Section 276.104(d) of this Part, 

shall have their tires inflated to tire sidewall pressure. 

11) Background concentrations of HC, CO, NO[x], and C0[2] shall 

be sampled as specified in 40 CFR 85.2226(b)(2)(iv) (Draft), 

incorporated by reference in Section 276.104(a) of this Part, 

to determine background concentration of dilution air. The 

sample shall be taken for a minimum of 15 seconds within 120 

seconds after the start of the transient driving cycle,. using 

the same analyzers used to measure tailpipe emissions. 

Average readings over the 15 seconds for each gas shall be 

recorded in the test record. Testing shall be prevented 

until the average ambient background levels are less than 20 

ppmC HC, 35 ppm CO, and 2 ppm NO[x] (when applicable), or 

outside ambient air levels (not influenced by station 

exhaust), whichever are greater. 

12) While a lane is in operation, the CVS shall continuously 

purge the CVS hose between tests. The blower may be turned 

off if the CVS is not in operation, but the system shall be 

purged for 2 minutes prior to the start of a test if the 

blower has been turned off. The off time shall be computer 

mon itored and recorded to a history file for quality 

assurance. 

c) Equipment Positioning and Settings 

Vehicle positioning and settings shall be conducted according to 

the method specified in 40 CFR 85.222l(c) (Draft), incorporated by 

reference in Section 276.104(a) of this Part, with the following 

exceptions: 

1) the cooling fan need only be activated when the ambient 

temperature exceeds 72°F; 

2) the parking brake should only be activated on front wheel 

drive vehicles when possible; and

Gear shifts shall occur at the points in the driving cycle 1009 

where the specified speeds are obtained. For vehicles with 1010 

fewer than 6 forward gears, the same schedule shall be lOll 

followed with shifts above the highest gear disregarded. 1012 

Speed excursion limits shall apply as follows: 1014 

A) The upper limit is 2 mph higher than the highest point 1016 

on the trace within 1 second of the given time. 1017 

B) The lower limit is 2 mph lower than the lowest point on 1019 

the trace within 1 second of the given time. 1020 

C) Speed variations greater than the tolerances (such as 1022 

may occur during gear changes) are acceptable provided 1023 

that they occur for no more than 2 seconds on any 1024 

occasion. 

D) Speeds lower than those prescribed during the 

underpowered intervals of seconds 4 through 18, 97 

through 115, and 154 through 219 of the trace will allow 

the station supervisory personnel the option of 

overriding the automatic void of the test. As part of 

the override, the station supervisory personnel will be 

required to witness a second trace. s~~~ds-%ow~r-than

il During the station supervisory personnel's witness 

of the second or subsequent trace, the test will 

be aborted if a speed variation exists for more 

than two seconds on any occasion outside the 

underpewered intervals. If this condition is 

detected, the test shall be stopped, and may be

trace, outside the underpowered intervals. 1045 

iii) Station supervisory personnel overrides can be 1047 

used to accept the results of the witnessed second 1048 

or subsequent trace(s) if the override is flagged 1049 

with a trace statistic or distance error so long 

as it meets the requirements specified in 1050 

subsections (e)(4)(D)(i) and (e)(4)(D)(ii).

~P) The test shall be aborted and immediately restarted if 1059 

speed excursion limits are exceeded, except as described 1061 

in subsection (e)(4)(D) of this Section. 1062 

Speed Variation Limits 1064 

The speed variation limits shall be determined by one of the 1066 

following methods: 1067 

A) Linear Regression Method 1069 

i) A linear regression of feedback value on reference 1071 

value shall be performed on each transient driving 1072 

cycle for each speed using the method of least 1073 

squares, with the best fit equation having the 

form: y = mx + b, where: 1074 

y = The feedback (actual) value of speed 1076 

m = The slope of the regression line 1078 

x = The reference value 1080 

b = The y-intercept of the regression line 1082 

ii) The SE of y on x shall be calculated for each 1084 

regression line. A transient driving cycle lasting 1085 

the full 240 seconds that exceeds the following 

criteria shall be void and the test shall be 1086 

repeated: 

SE = 2.0 mph maximum 1088 

m = 0.96 - 1.01 1090 

r(2) 

b 

= 0.97 minimum 

= 2.0 mph 

1092 

1094 

iii) A transient driving cycle that ends before the 1096 

full 240 seconds that exceeds the following 1097 

criteria shall be void and the test shall be 

repeated: 

SE = (Reserved) 1099 

m = (Reserved) 1101 

r(2) = (Reserved) 1103 

b = (Reserved) 1105 

B) Positive Kinetic Energy (PKE) Method 1107 

i) The speed variation limits shall be determined by 1109 

the following equation for Positive Kinetic Energy 1110 

(PKE): 

N X 

PKE =+ SUM PPltl / INT x dx 

t=O 0 

where: PP[t] = V(2)[t] - V(2)[t-l] 

mi(2)/hr(2) for V[t] > V[t-1] 

PP[t) = 0 for V[t] ~ 0

1115 

1117 

1120 

1122 

1124 

x = distance (miles) 1126 

PP[t] = Positive Specific Power at time t 1128 

V[t] = Velocity at time t 1130 

V[t-1] = Velocity at time t-1 1132 

ii) A transient driving cycle lasting the full 240 1135 

seconds with a PKE value that is below the lower 1136 

PKE limit for passing vehicles or above the upper 

limit for failing vehicles shall be void and the 1137

Upper Limit: PKE > 3456 mi/hr(2} 1139 

Lower Limit: PKE < 3082 mi/hr(2} 1141 

iii) A transient driving cycle that ends before the 1143 

full 240 seconds with a PKE value that is below 1144 

the lower second-by-second PKE limit for passing 

vehicles or above the upper second-by-second PKE 1145 

limit for failing vehicles shall be void and the 1146 

test shall be repeated. The second-by-second upper 

and lower PKE limits are specified in Section 1147 

276.Table B. 

iv) PKE values shall not be used to make early 

pass/fail determination. 

The actual distance traveled for the transient driving cycle 

shall be measured. If the absolute difference between the 

measured distance and the theoretical distance for the actual 

test exceeds 0.05 miles, the test shall be void and shall be 

repeated. 

The vehicle shall be rejected if, during the course of the 

transient loaded mode test, station supervisory personnel 

verify that the test cannot be completed due to the 

mechanical condition of the vehicle. 

Inertia Weight Selection 

Operation of the inertia weight selected for the vehicle 

shall be verified as specified in Section 276.506(a) of this 

Part. For systems employing electrical inertia simulation, 

an algorithm identifying the actual inertia force applied 

during the transient driving cycle shall be used to 

determined proper inertia simulation. 

The CVS operation shall be verified for each test for a 

CFV-type CVS by measuring either the absolute p~essure 

difference across the venturi or measuring the blower vacuum 

behind the venturi for minimum levels needed to maintain 

choke flow for the venturi design. The operation of an 

SSV-type CVS shall be verified throughout the test by 

monitoring the difference in pressure between upstream and 

throat pressure. The minimum values shall be determined from 

system calibrations. Monitored pressure differences below 

the minimum values shall void the test, and a test lane 

system lockout shall be initiated. No further testing shall

Transient Loaded Mode Exhaust Gas Test Score Calculations 

The transient loaded mode exhaust gas test score shall be 

determined according to the method specified in 40 CFR 85.2205(b) 

(Draft), incorporated by reference in Section 276.104(a) of this 

Part, with the following exceptions: 

l) The Phase 2 scores for the test shall be determined by 

dividing the sum of the mass of each pollutant obtained in 

each second of the Phase 2 test by the number of miles driven 

in the Phase 2 test. The first data point is the sample 

taken from t=94 to t=95. The Phase 2 test score shall be 

determined by the following equation: 

s 

SUM grams of emissions 

Phase 2 gpm = t=94 

s

test. 

2) NO[xe] = Nitrogen oxide concentration of the dilute exhaust 

sample as measured in ppm and multiplied by 1.03. 

3) NO[xd] = Background nitrogen oxide concentration of the 

dilution air, sampled as described in 40 CFR 85.222l(b)(5) 

(Draft), incorporated by reference in Section 276.104(a) of 

this Part, as measured in ppm and multiplied by 1.03.

with a PKE value t hat is below the lower PKE limit for 

passing vehicles or above the upper limit for failing 

vehicles shall be void and the test shall be repeated: 

Upper Limit: PKE > 3456 mi/hr(2 ) 

Lower r.imi t : PRE < 3082 mi/hr ( 2 ) 

iii ) A transient driving cycle that ends before the full 

240 seco nds wi th a PKE value that is below the lower 

second-by-second PRE limit for passing vehicles or 

above the upper second-by-second PKE limit for failing 

vehicles shall be void and the test shall be repeated . 

The second- by-second upper and lower PKE limits are 

specified in Section 276 . Table B. 

iv) PRE values shall not be used to make early pass/fail 

determination . 

The ac tual distance traveled for the transient driving cycle 

shall be measured . If the absolute difference between the 

measured distance and t he theoretical distance for the actual 

test exceeds 0 . 05 miles, t he test shall be void and ___ shall be 

repeated . 

The vehicle shall be rejec ted if, during the course of the 

transient loaded mode test, station supervisory personnel ve rify 

that the test cannot be completed due to the mechanical condition 

of the vehicle.
