### Summary of Auto/Oil E10+ Test Progr am for Highway "Non-FFV" Vehicles
Item # Title Project # Status

1 Fuel Storage and Handling CRC AVFL-15 AVFL-15 preliminary work is underway; more funding needed

The industries understand system components for E10 and also for E85, but it is unclear at what level of ethanol

content above 10% that E 10-rated parts fail. The object ive of AVFL-15 is to determine the durability of wetted fuel components/systems. Fuel storage and handling is studied in component/system s durability testing. Resource constraints limit the scope of AVFL-15, preventing a def initive program, hence addition al testing is required.

2 Base Engine Durability CRC CM-136-09 The initial phase of this program is underway The industry knows what is required to upgrade engine components for E22, E85 and E100. Some automakers have done internal testing and have found sensitivity to intermediate ethanol blend levels for non-FFV vehicles. The testing for base engine durab ility (base refers to the actual machiner y as opposed to the s ensors, controls and the like) is embodied in CRC RFP No. CM-136-09. The init ial round of vehicle testing is nearing completion.

3 On-Board Diagnostics (OBD) Evaluation CRC E-90 The pilot phase of E-90 is complete; more data needed The automakers have a good understanding of the theoretical effects of et hanol on OBD. The issue is how OBD systems actually work in a fleet of aged production vehicles. The initial phas e of vehicle data collection has been completed and the final report is on www.crcao.org . Two additional phases are planned for 2010.

4 Tailpipe Emissions for

SULEV Vehicles and at Cold Ambient Temperatures CRC E-92 Planning for future work is ongoing pending available funding Starting with the 2010 model year automakers have to m eet Non-Methane Hydrocarbon (NMHC) emissions at a 20F start temperature. Automakers have had to meet st ringent SULEV emissions at a 50F start temperature for many years. The enleanment due to oxygen in ethanol and the low volatilit y of the ethanol porti on of the fuel blend at low temperature gives concerns that existing and planned ve hicles designed for federal and California emissions test fuels will not meet their required emissions standards when operated on mid- level ethanol blends. This program does not envision vehicle aging, however limited funding has delayed the start of this test program.

5 Catalyst Durability and Degradation CRC E-87 The course and fate of this program is currently unclear The issue of accelerated catalyst aging with intermedi ate ethanol blends was well- documented in the Orbital research study conducted in Australia. DOE found that 44% of vehicles they tested had the same control architecture as those that had problems with E20 in Au stralia and their data, when combined with CRC E-87-1,

data indicate that 35-45% of the US fleet will have this sensitive c ontrol architecture. E-87-1 was funded by CRC and the report is on www.crcao.org . Durability testing to identify this phenomenon is the scope of follow-on testing which is underway generating data through DOE fu nding with minor support funding from CRC.

6 Evaporative Emissions Durability CRC E-91 This program is underway

As reported in previous intermediate ethanol blend res earch coordination meetings , CRC has conducted research projects under E-65 and E-77 on the effects of ethanol on evaporative emissions. However, these tests have all looked at the effects of short exposur es. This project is defined in CRC RF P No. E-91. The contract has been awarded, test vehicles have been acquired, and initial data collection is underway for the 2010-2011 program.

7 Emissions Inventory and Air Quality Modeling A-67 / A-73 A-67 results to be released in early 2010 and A-73 is planned

for a completion late in 2010 The CRC Atmospheric Impacts Co mmittee is leading this ef fort in coordination with other stakeholders. A-67 (Estimating Ozone from Fuel Reformul ation) and A-73 (Emissions Modeling and Air Quality Modeling) are the two CRC programs that will address this s ubject. These efforts will rely on obtai ning emissions data from the other CRC programs above.

8 Exhaust Emissions on Vehicles Aged On Mid-Level

Ethanol Blends CRC New Project Portions of this work will be

addressed under A-73

A good collection of aged vehicle data w ill be acquired as part the overall program effort. These data will be used to assess direct emissions impacts from intermedi ate ethanol blends and for condu cting air quality modeling

evaluations.
