Cold Start and Transients
(Session Code: PFL290)

Room 414 A/B  8:00 a.m.

This session focuses on both SI and CI combustion and mixture preparation during cold start and transient engine operation. Example topics include engine performance, emissions, control strategies and calibrations for cold start and transient operation impact on NOx, PM, HC, CO, and CO2 emissions; also including the impact of variable valve timing, spark, and turbocharger controls.

Organizers - Eric W. Curtis, Ford Motor Co.; O. El Ganaoui-Mourlan, IFP School; Peter Moilanen, Ford Motor Co.; Hamid Servati, ServoTech. Engineering
