Dilute SI Combustion
(Session Code: PFL216)

Room 413 A  1:00 p.m.

This session focuses on the dilute SI combustion processes including lean, stratified, and EGR operation. Papers cover both 4-stroke and 2-stroke engines characterized by 1) ignition by an external energy source that serves to control combustion phasing, and 2) a combustion rate that is limited by flame propagation.

Organizers - Christopher J. Chadwell, Southwest Research Institute; Richard S. Davis, General Motors Co.; Mark C. Sellnau, Delphi Corp.; Ruonan Sun, US Environmental Protection Agency
Chairpersons - Mark C. Sellnau, Delphi Corp.; Christopher J. Chadwell, Southwest Research Institute
