Particulate measurements: Ethanol and Butanol in DISI Engines

Purpose and Objectives

Because of the increasing use of ethanol, the growing number of DISI engines available from vehicle manufacturers, and of the impact on the design and effectiveness of aftertreatment systems, there is a need to understand particulate formation due to interaction of ethanol-gasoline blends in DISI engines. Initial research has shown that low-level ethanol blends decrease PM formation, however further confirmation is needed. Particulate formation is basically unknown in the cases of butanol blends. This sub-task to Task 35 is designed to shed light on these issues.

Activities

The project involves comparing direct injection of ethanol and butanol blended fuels to direct injection of gasoline injected fuels. Steady-state engine dynamometer tests as well as transient chassis dynamometer tests will be performed with gasoline direct-injection engines and emissions, power, and fuel economy will be compared.
