Subject: Monthly Progress Report No. 11 for th e Period August 1, through August 31, 2009; for the program, "Catalyst Screening and Durability for Intermediate Ethanol Blends," UT-Battelle/Oak Ridge Na tional 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 ca talyst and oxygen sensor temperat ures. This project will also generate valuable data on vehi cle emissions and performance.

Vehicles selected for this st udy will include a wide range of manufacturers across several model years. Some of the vehicles that will be tested include vehi cles that have been identified as having leaner and hotter opera tion 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 unknow n 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, a nd 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 perf ormed on multiple sets of matched vehicles. For each matched set, vehicles are to be aged a nd emissions tested on the four fuel blends (E0, E10, E15, and E20). Emissions testing will be performed at three adde d service accumulation levels: 0 miles (start of service accumula tion), between 25,000 and 50,000 miles (mid service accumulation level), and at the end of the vehi cle’s full-useful life (nominally 120,000 miles). Beginning in August 2009, selected ne w 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 emi ssions test workbook has been developed for the purpose of archiv ing project data and posting data to the project ftp web site. The emissions data posted to the ftp web site a nd data reported in this progress report include calculated emission rates of non-methane organi c gas (NMOG) and fuel economy calculated by carbon balance. Previous progress reports contai ned fuel economy results that were calculated using Federal Code of Regulations (CFR) met hodology for vehicle emissions certification with certification fuel (gasoline). For this project, the carbon balance calculation method is preferred for comparing fuel economies from fuel s with different ethanol contents.

This progress report also in cludes methanol, ethanol, 2-propanol, formaldehyde, and acetaldehyde emissions data that has been correct ed for collection media interferences in the measurement process. As mentioned in th e previous progress report, a methodology for determining the limit of detection (LOD) and th e 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 ye ars as vehicles emit

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

above are used in the calculation of NMOG.

2.2 Honda Accords

Honda Accord vehicles ORHA0, OR HA15, and ORHA20 underwent emissions testing this reporting period. Thes e 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 da ta at 0 and 50,000 test miles, and 120,000 odometer miles for the Accords r un to date are provided in Tables 1, 2, and 3, respectively. Honda Accord vehicle ORHA10B continued serv ice accumulation on the SwRI Mileage Accumulation Dynamometers, and it is expected to reach full-useful life by midSeptember. Emissions tests fo r vehicle ORHA10B with the four project test fuels will be scheduled shortly after the comple tion of the service accumulation.

2.3 Chevrolet Silverados

The Chevrolet Silverado vehicle set con tinued 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. Em issions test summaries at 0 and 50,000 test miles are provide d in Tables 4 and 5, respectively.Brian H.

## 2.4 Nissan Altimas

The Nissan Altima vehicle set underwent em issions 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 zer o-mile emissions testing on the four project test fuels this reporting period. Taurus emissions data are give n 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 coe fficients 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 e xhibited 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 mana ger, 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 di rected SwRI to loca te and purchase three

2006 Chevrolet Cobalts with 2.2L fou r-cylinder engines. These vehicles have been procured and have begun preparation for testing in this project. Test preparat ions include re-flashing one of the ECMs to the more current engine calibration.

## FIGURE 1. 2006 CHEVROLE T COBALT VEHICLE GROUP

2.8 Vehicle Oil Consumption

Oil consumption history for the Honda A ccord, Chevrolet Silver ado, 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 th at the fuel contai ned 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 fu el 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 ot her 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.

### Brian H. West Oak Ridge National Laboratory September 15, 2009 Page 14 of 15



## 3.0 WORK PLANNED FOR THE NEXT REPORTING PERIOD

Honda Accord ORHA10B will continue servi ce accumulation into September, and then it will be scheduled for full-useful life (FUL) emi ssions testing. The Chevrolet Silverado vehicle

set is also scheduled to finish servi ce 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 accumu lation 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 ar rived and will continue to be prepared for project work.

Vehicle emissions data proces sing for new tests will continue and incorporate the use of the newly developed data calculation and ar chiving workbook. This workbook will calculate vehicle fuel economy using the ca rbon balance method. The previous ly generated da ta 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-cont aining gasoline by the end of 2009.

Oak Ridge is working with project stakeholde rs 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 sugges ted meeting date follows the SAE Internatinal Powertrains, Fuels & Lu bricants meeting being held in Sa n Antonio November 2-4, 2009. This proposed meeting date has b een communiticated by CRC to th e project review committee

members.
