Subject: Monthly Progress Report No. 8 for the Period May 1, through May 31, 2009; for theprogram, "Catalyst Screening and Durability for Intermediate Ethanol Blends," UTBattelle/Oak Ridge National Laborator y 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).

# 2.0 PROGRESS FOR THE PERIOD MAY 1-31, 2009

2.1 Honda Accords, Chevrolet Silverados, and Nissan Altimas

The Honda Accord vehicle set resumed its service accumulation on the SwRI Mileage Accumulation Dynamometers this reporting pe riod. The Chevrolet S ilverado vehicle set completed its service accumulation to 50,000 test m iles. The Nissan Altimas were installed on the Mileage Accumulation Dynamometers as the Silverados were rem oved. Vehicle service

accumulation for the Accords and the Altimas is e xpected to continue th rough the next reporting period.

Short- and long-term fuel trim data, along with lubricating oil change interval history to date, is given in Appendix A for the Honda A ccord, Chevrolet Silver ado, and Nissan Altima vehicle sets. Graphs of vehicle oil consumpti on are provided in Appendix B, and compression and leak down tests results are included in Appendix C.

The Chevrolet Silverado vehicle set is scheduled to begin 50,000 test mile WOT performance and emissions testing in June. The addition of mid-le vel (50,000 mile) WOT performance tests and additional WOT perfor mance tests on vehicles ORCS10 and ORCS15 using fuels E10 and E15, respectiv ely, was requested by the Oak Ri dge technical project monitor following discussions with CRC. No vehicle em issions tests were performed this reporting period.

2.2 Ford Taurus’

The Ford Taurus vehicle set continued its preparation for emissions testing and service accumulation this past reporting period. A Ford Ta urus was fitted with an instrumented exhaust system spacer (described in the previous progr ess report), but it was discovered that there was

insufficient clearance for the modified exhaust system when hard acceleration engine rocking was taken into account. SwRI has begun discus sions with Oak Ridge and Ford Motor Company to investigate another exhaust system instrument ation approach. The resolution of this concern will continue into the next repor ting period. With a quick resoluti on, the Ford Taurus vehicle set can be scheduled to begin zero-mile FTP emissions and WOT performance testing in late June.

2.3 Vehicle Procurement

Southwest Research Institute has located and purchased four matching 2007 Dodge Caravan minivans equipped with 3.3L V-6 engines fo r this project. These vehicles are expected to be received by SwRI the first week in June.

2.4 Fuels

The eighth tanker truck of Top Tier regular unleaded gasoline was received by SwRI this reporting period. The fuel was chec ked prior to SwRI acceptance to ensure that the fuel did not contain ethanol. The fuel was accepted by SwRI and delivered to the RE 0 mileage accumulation fuel storage tank.

# Additional batches of RE15 and RE20 durabili ty fuels were blended. The analytical evaluations of the fuel sample s from the tanker truck and the RE15 and RE20 fuels are given in Appendix D.

2.5 Data Format and Archiving

Emissions test data stored in the vehicle em issions test system computer were reformatted and stored in project test folders. Each test co nducted for this program has its own data folder. Federal Test Procedure (FTP) emissions test data, including laborator y alcohols and aldehydes emission data, as well as conti nuous exhaust system temperature, lambda, and vehicle on-board

data is sorted and stored in each test folder. Data format and archiving activities will continue into the next reporting period.

2.6 Project Review Meeting

A technical project review meeting has b een scheduled for June 17, 2009, for Oak Ridge and CRC project committee members. SwRI will host the meeting in San Antonio, Texas. The meeting will cover the technical progress of the vehicle sets test ed to date, and future program directions will be discussed. Topics to be covered will include the FTP emissions test results, the WOT performance test data, vehicle service ac cumulation, and fuel blending activities. Data format and data archiving development for future statistical analysis will also be discussed.

3.0 WORK PLANNED FOR THE NEXT REPORTING PERIOD

The Honda Accords will continue their vehicle service accumulation on RE0, RE10, RE15, and RE20 fuels. Vehicles ORHA0, ORHA 15, and ORHA20 will continue their service

accumulation to full-useful life. Vehicle ORHA 10B will continue its service accumulation to 50,000 test miles. An additional SwRI Mileage Accumulation Dynamometer will be dedicated to Oak Ridge and CRC for vehicle ORHA10B when it is ready to begin se rvice accumulation to full-useful life (following emissions testing at 50,000 test miles).

The Silverado vehicle set will begin mi d-level WOT performance and FTP emissions tests with emissions test fuels E0, E10, E15, and E20. The additional WOT performance tests requested are included.

The Nissan Altimas will continue service accumulation on the Mileage Accumulation Dynamometers. Altima vehicle service accumula tion will continue through the next reporting period.

The Ford Taurus vehicle set will be in strumented for temperature and lambda

measurement. Federal Test Procedure emissions and WOT performance testing will likely begin

in late June.

The four 2007 Dodge Caravans will begin vehicle check-in and test preparation immediately following their receipt by SwRI.
