Subject: Monthly Progress Report No. 11 for the Period August 1, through August 31, 2009; 

for the program, "Catalyst Screening and Durability for Intermediate Ethanol 

Blends," UT-Battelle/Oak Ridge National Laboratory Subcontract No. 4000071456, 

SwRI Project 03.14530. 

1.0 INTRODUCTION 

 The objective of this project is to help quantify emissions system durability of E15 and 

E20 on the US fleet. Specifically, this project will study the effects of ethanol blends on openloop stoichiometry and resulting catalyst and oxygen sensor temperatures. This project will also 

generate valuable data on vehicle emissions and performance. 

Vehicles selected for this study will include a wide range of manufacturers across several 

model years. Some of the vehicles that will be tested include vehicles that have been identified 

as having leaner and hotter operation on ethanol blends than on gasoline when in wide-open 

throttle (WOT) open-loop operation. Other vehicles will be tested because of their large 

numbers in the in-use vehicle fleet. New vehicles with unknown open-loop fuel control at WOT 

may also be selected. 

 In this project, SwRI will age vehicles and emission control systems operating on three 

levels of ethanol blended fuels (E10, E15, and E20) and compare emissions and vehicle 

performance to similar vehicles operating on the base gasoline (E0). Vehicle service 

accumulation and emissions testing are to be performed on multiple sets of matched vehicles. 

For each matched set, vehicles are to be aged and emissions tested on the four fuel blends (E0, 

E10, E15, and E20). Emissions testing will be performed at three added service accumulation 

levels: 0 miles (start of service accumulation), between 25,000 and 50,000 miles (mid service 

accumulation level), and at the end of the vehicle’s full-useful life (nominally 120,000 miles). 

Beginning in August 2009, selected new vehicle sets will be tested with E0, E15, and E20 fuels.

2.0 PROGRESS FOR THE PERIOD AUGUST 1-31, 2009 

2.1 Data Format and Processing 

 Data processing activities have continued. A new emissions test workbook has been 

developed for the purpose of archiving project data and posting data to the project ftp web site. 

The emissions data posted to the ftp web site and data reported in this progress report include 

calculated emission rates of non-methane organic gas (NMOG) and fuel economy calculated by 

carbon balance. Previous progress reports contained fuel economy results that were calculated 

using Federal Code of Regulations (CFR) methodology for vehicle emissions certification with 

certification fuel (gasoline). For this project, the carbon balance calculation method is preferred 

for comparing fuel economies from fuels with different ethanol contents. 

This progress report also includes methanol, ethanol, 2-propanol, formaldehyde, and 

acetaldehyde emissions data that has been corrected for collection media interferences in the 

measurement process. As mentioned in the previous progress report, a methodology for 

determining the limit of detection (LOD) and the limit of quantification (LOQ) for alcohols and 

aldehyde measurements was established for this project. The new methodology determines how 

to properly address collection media interferences in the measurement process when the exhaust 

emission samples themselves are at levels similar to the interferences. The need for this 

additional analysis has become more pronounced over the past several years as vehicles emit 

lower levels of emissions. Emissions of the five alcohol and aldehyde compounds mentioned 

above are used in the calculation of NMOG. 

2.2 Honda Accords 

 Honda Accord vehicles ORHA0, ORHA15, and ORHA20 underwent emissions 

testing this reporting period. These emissions tests were performed at vehicle “full-useful life” 

(nominally 120,000 miles as measured on the odometer of the highest mileage vehicle). Updated 

FTP emissions test data with NMOG and carbon balance fuel economy data at 0 and 50,000 test 

miles, and 120,000 odometer miles for the Accords run to date are provided in Tables 1, 2, and

3, respectively. Honda Accord vehicle ORHA10B continued service accumulation on the SwRI 

Mileage Accumulation Dynamometers, and it is expected to reach full-useful life by midSeptember. Emissions tests for vehicle ORHA10B with the four project test fuels will be 

scheduled shortly after the completion of the service accumulation. 

2.3 Chevrolet Silverados 

 The Chevrolet Silverado vehicle set continued service accumulation on the mileage 

accumulation dynamometers. This Silverado vehicle set is ahead of schedule and is expected to 

continue service accumulation to mid-September. 

During this reporting period, FTP emissions test results for NMOG and carbon-balance 

fuel economy were calculated with the new data processing protocol. Emissions test summaries 

at 0 and 50,000 test miles are provided in Tables 4 and 5, respectively.

2.4 Nissan Altimas 

 The Nissan Altima vehicle set underwent emissions testing at 50,000 test miles this 

reporting period. Emissions tests performed earlier at zero test miles were reprocessed with the 

new protocol. Emissions test summaries for the Nissan Altimas at 0 and 50,000 test miles are 

provided in Tables 6 and 7, respectively. The Altimas will resume service accumulation when 

the Silverados complete service accumulation. 

2.5 Ford Tauruses 

 The Ford Taurus vehicle set completed its zero-mile emissions testing on the four project 

test fuels this reporting period. Taurus emissions data are given in Table 8. The Tauruses will 

resume service accumulation in September. 

2.6 Dodge Caravans 

 In the previous reporting period, the Dodge Caravan vehicle set began emissions testing, 

but the work was stopped when it was determined that the wrong dynomometer coefficients were 

selected. Dodge Caravans ORDC0, ORDC10, and ORDC15 began zero-mile emissions testing 

with the correct dynamometer coefficients this reporting period. Preliminary emissions data for 

these three vehicles at zero test miles are given in Table 9. As previously reported to the Oak 

Ridge project manager, Caravan ORDC20 had exhibited higher than expected NOx and HC 

emissions. It is believed that the catalyst on this vehicle had become less active. The exact 

cause of the high emissions and possible catalyst deactivation was not specifically determined.

At the request of the Oak Ridge project manager, SwRI will locate a replacement for Dodge 

Caravan ORDC20. A search for a replacement vehicle has begun. 

2.7 Vehicle Procurement – Chevrolet Cobalts 

 The Oak Ridge project manager previously directed SwRI to locate and purchase three 

2006 Chevrolet Cobalts with 2.2L four-cylinder engines. These vehicles have been procured and 

have begun preparation for testing in this project. Test preparations include re-flashing one of 

the ECMs to the more current engine calibration. The Cobalt vehicle set is a three-vehicle set

FIGURE 1. 2006 CHEVROLET COBALT VEHICLE GROUP 

2.8 Vehicle Oil Consumption 

 Oil consumption history for the Honda Accord, Chevrolet Silverado, and Nissan Altima 

vehicle sets has been recorded by weight. Graphs of oil consumption versus test miles are 

provided in Appendix B. There are no concerns with vehicle oil consumption at this time. 

2.9 Mileage Accumulation Fuel 

Two additional tanker trucks of E0 fuel (approximately 15,000 total gallons) were 

purchased this reporting period. Prior to acceptance, a sample of the fuel from each truck was 

analyzed to ensure the quality and that the fuel contained no ethanol. 

 As discussed in the previous progress report, there is a concern that E0 fuel will not be 

available at the terminal currently providing E0 fuel for the program. It is possible that the 

terminal currently supplying E0 fuel will have this fuel only through December of 2009. SwRI 

began work with Oak Ridge and CRC to identify other fuel terminals that could potentially offer 

E0 fuel for the remainder of the program. CRC sent a request for information to its members by 

e-mail this past reporting period. Some responses to this e-mail have been received by SwRI. 

SwRI will follow-up on this request for information.

3.0 WORK PLANNED FOR THE NEXT REPORTING PERIOD 

 Honda Accord ORHA10B will continue service accumulation into September, and then it 

will be scheduled for full-useful life (FUL) emissions testing. The Chevrolet Silverado vehicle 

set is also scheduled to finish service accumulation to FUL in September. 

The Nissan Altima vehicle set will resume service accumulation to a nominal 120,000 

odometer miles (on the highest mileage vehicle) following completion of the current set of 

emissions tests and the completion of the service accumulation of the Silverado vehicle set. The 

Ford Taurus vehicle set will begin service accumulation following the zero mile emissions tests. 

 The Dodge Caravans ORDC0, ORDC10, and ORDC15 will continue emissions testing 

and data analysis. A search for a vehicle to replace Dodge Caravan ORDC20 will continue. The 

Chevrolet Cobalt vehicle set has arrived and will continue to be prepared for project work. 

 Vehicle emissions data processing for new tests will continue and incorporate the use of 

the newly developed data calculation and archiving workbook. This workbook will calculate 

vehicle fuel economy using the carbon balance method. The previously generated data sets will 

continue to be re-processed and put in the new workbook form. Data postings to the project ftp 

site will be made periodically. 

 SwRI will continue to work with Oak Ridge and CRC to determine a source of E0 fuel as 

an alternative to the current supplying terminal. It is possible that the current terminal will be 

transitioning to ethanol-containing gasoline by the end of 2009. 

 Oak Ridge is working with project stakeholders to determine specifications for the next 

project test vehicles. The next two or more sets of vehicles are expected to be specified in 

groups of three vehicles each. These vehicles will be aged on E0, E15, and E20 fuels. 

 A date for the next project review meeting to be held in San Antonio has been discussed, 

and this date is November 5, 2009. This suggested meeting date follows the SAE Internatinal 

Powertrains, Fuels & Lubricants meeting being held in San Antonio November 2-4, 2009. This 

proposed meeting date has been communiticated by CRC to the project review committee 

members.
