Subject: Monthly Progress Report No. 6 for the Period March 1, through March 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).

 The four Honda Accords began their service accumulation on the SwRI Mileage 

Accumulation Dynamometers during the previous reporting period. Honda Accord ORHA10 

was observed to have a high oil consumption rate (approximately one quart every 2,000 miles). 

A graph of Honda Accord oil consumption vs. time is provided in Appendix A. 

 Following an investigation into the high oil consumption, Oak Ridge and CRC decided to 

permanently discontinue service accumulation on Honda Accord ORHA10 and replace it with 

another Honda Accord. SwRI identified a candidate Accord for purchase in Houston that 

matches the criteria of the existing Accord vehicle set. This candidate vehicle was purchased 

and delivered to SwRI. A description of the replacement Honda Accord, ORHA10B, is given in 

Appendix B. 

 The three remaining Honda Accords continued service accumulation on SwRI Mileage 

Accumulation Dynamometers. Oil change intervals, as determined by the Honda Maintenance 

Minder (service and oil change indicator that displays the percentage of oil life remaining), are 

occurring regularly at approximately 7,000 miles of standard road cycle (SRC) service. SwRI is 

changing the oil on all the vehicles at the added service accumulation mileage level that the 

leading vehicle’s maintenance minder indicates as "five percent oil life remaining." Oil change 

interval history for the Honda Accords is included with the long-term fuel trim measurements in 

Appendix C. 

2.2 Chevrolet Silverados 

The Chevrolet Silverado test vehicles underwent FTP emissions testing with project fuels 

during the previous reporting period. Silverado WOT test results using E0 and E20 fuel blends 

with all four vehicles have been reviewed and posted to the project ftp site. Federal Test 

Procedure emissions tests were conducted with E0, E10, E15, and E20 emissions test fuels 

during the previous reporting period. Silverado vehicle emission test results, including FTP 

composite ethanol, formaldehyde, and acetaldehyde data are provided in Table 2. 

 The four Chevrolet Silverado test vehicles began SRC service accumulation this 

reporting period. There was some question as to what the programmed dynamometer road load 

force should be for the Chevrolet Silverados because the SRC required a road load that resulted 

in a vehicle transmission shift late in the 0 to 80mph acceleration portion of the SRC. Following 

consultation with Oak Ridge and CRC representatives, it was decided that the Silverados would 

be run with a slightly lower road load force at this point in the acceleration so that the vehicle 

transmission would not repeatedly shift up and down and cause instability in the road load at this 

point. This selection was made after assuming that a human driver would likely approach this 

road load gently from the low side to avoid erratic transmission shift events. Silverado service 

accumulation is scheduled to continue through the end of May.

2.3 Nissan Altimas 

 Southwest Research Institute began vehicle preparation of the four 2008 Nissan Altima 

test vehicles. Vehicle FTP check-out emissions tests were performed with E0 fuel, and it was 

noticed that the Altima emissions were very close to the EPA Bin 5 50K-mile emission 

standards. Discussions ensued between Oak Ridge, SwRI, and Nissan, and Nissan recommended 

that the automatic transmission control units (ATCUs) be re-flashed with software for testing on 

a two wheel dynamometer. After Oak Ridge discussed these results with CRC committee 

members, it was decided to send the ATCUs to Nissan Technical Center for the re-flash. The 

Altima emissions testing will resume following the ATCU programming change.

2.4 Ford Taurus’ 

 The four Ford Taurus test vehicles have been named ORFT0, ORFT10, ORFT15, 

ORFT20, and will be aged on E0, E10, E15, E20 fuels, respectively. The vehicle naming 

convention for the Taurus’ is given in Table 3. Vehicle designations were assigned randomly. 

Vehicle and fuel identification labels have been put on each vehicle. The Ford Taurus test 

vehicle set is shown in Figure 1.

2.5 Fuel Blending 

 The E0, E10, E15, and E20 emissions test fuels for the Chevrolet Silverados and the 

Nissan Altimas were blended during the previous reporting period. Blending of the emissions 

test fuels for the Ford Taurus and the next vehicle set began this reporting period. Blending of 

these batches of emissions test fuels is scheduled to continue through April. 

 A service accumulation fuel quality audit was performed at the mileage accumulation 

dynamometers (MADs). Fuel samples were taken from the four different MAD lane dispensers 

used to refill test vehicle fuel tanks. These samples were analyzed in SwRI’s Petroleum Products 

Research Department for oxygenate content using the ASTM D5599 procedure. Fuel analysis 

audit results, given in Appendix D, verify that the correct fuels are being dispensed into the 

appropriate vehicles. 

2.6 Vehicle Procurement 

Southwest Research Institute took receipt of the four 2008 Nissan Altima and four 2008 

Ford Taurus test vehicles during the previous reporting period. The replacement for Honda 

Accord ORHA10, designated as vehicle ORHA10B, was received this period. No other vehicles 

or vehicle models have been identified for procurement. 

3.0 WORK PLANNED FOR THE NEXT REPORTING PERIOD 

 The three Honda Accords will continue service accumulation until each vehicle reaches 

50,000 test miles as measured by the vehicle odometer. The Accords are expected the reach this 

level of service accumulation approximately April 20, 2009. The vehicles will then begin midlevel (50k mile) WOT performance and FTP emissions tests with emissions test fuels E0, E10, 

E15, and E20. The addition of mid-level WOT performance tests was requested by the Oak 

Ridge technical project monitor. The replacement Honda Accord, vehicle ORHA10B, is 

expected to begin zero-mile WOT performance and FTP emissions tests during the next 

reporting period. 

 The Chevrolet Silverado vehicle set will continue service accumulation testing with 

mileage accumulation fuels RE0, RE10, RE10, and RE20. Silverado service accumulation is 

anticipated to continue through May. 

 The Nissan Altima exhaust systems will be instrumented for temperature and lambda 

measurement for WOT performance testing. Federal Test Procedure emissions testing will 

resume following the ATCU re-flash. 

 The Ford Taurus vehicle set will continue its preparation for emissions testing and 

service accumulation. The Taurus catalytic converter is close-coupled to the engine in a cast iron 

exhaust manifold and presents some instrumentation challenges. Oak Ridge, SwRI, and CRC 

will determine an instrumentation strategy for the Taurus exhaust systems.

 Project fuel blending activities will continue. Blending of emissions test fuels for the 

Taurus vehicle set and the next vehicle set is scheduled for April. Blending of the second batch 

of each of the vehicle service accumulation fuels RE10, RE15, and RE20 is also scheduled. 

 Oak Ridge requested that a meeting be held in San Antonio with Oak Ridge, SwRI, and 

the Battelle Statistics and Information Analysis Group to discuss project data format and data 

archiving. A format for project test data will be reviewed and discussed.
