THE FUEL CHEMISTRY IMPACTS OF GASOLINE/ETHANOL BLENDS IN AN HCCI SINGLE CYLINDER RESEARCH ENGINE

CRC Project No. AVFL-13b

Leaders:    S. W. Jorgensen
                  K. J. Wright

Scope and Objective

The objective of this project is to identify fuel chemistry that impacts operation in ‘gasoline’ homogenous charge compression ignition (HCCI) engines, including the impact of ethanol fuel.

This project is a follow-on to AVFL-13, using the same contractor, test engine, and protocol, with different fuel sets that explore the effect of ethanol on the HCCI combustion.   The AVFL-13 Final Report is available from the CRC website.

Current Status and Future Program

Dr. William Leppard, GM retired, is serving as a consultant to the committee on this project.

The first phase of AVFL-13b tested seven fuels, with ethanol content ranging from 0% to 30%. The second phase will test a set of nine fuels in 2008, with analysis and project reporting expected to conclude in early 2009.
