Technical Session Schedule

Wednesday, April 9

Abnormal SI Combustion (Part 1 of 2)
(Session Code: PFL213)

Room 413 A  1:00 p.m.

This session focuses on abnormal SI combustion processes including spark knock and preignition. 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. (Part 1 of 2)

Organizers - Terrence Alger, Southwest Research Institute; Richard S. Davis, John O. Waldman, General Motors Co.; Lurun Zhong, Chrysler Corporation LLC
Chairpersons - John O. Waldman, General Motors Co.; Terrence Alger, Southwest Research Institute
