Potential of Thermal Stratification and Partial Fuel Stratification for Reducing Pressure Rise Rate in HCCI Engines

摘要

The purpose of this study is to evaluate the potential of thermal stratification and partial fuel stratification for reducing pressure rise rate in HCCI engines. The computational modeling work is conducted using a multi-zone code with detailed chemical kinetics, including the effects of un-mixedness of fuel and thermal stratification on the onset of ignition and the rate of combustion.
