SAE 2012 World Congress & Exhibition

This session focuses on combustion technologies in 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. The scope of topics includes studies of
mixture formation, ignition, knock, engine efficiency, flame propagation, alternative fuels and emissions formation. Part 1 of 2: Pre-Ignition, Knock,
and Ignition

Trends of ever increasing power density, better fuel economy and now reduced emissions are increasing focus on turbocharging/ supercharging and
turbochargers/ superchargers, as part of overall engine system optimization. Increased amounts of EGR and use of aftertreatment devices present
new challenges. This session will cover conceptual, modeling and experimental studies relating to advanced turbochargers/superchargers and
advanced boosting systems to respond to above challenges.
