Numerical Simulation of PCCI-DI combustion Engine Fueled with DME(PartI)

TAB breakage model is substituted by the WAVE broken model.PSR(Partially-Stirred-Reactor) combustion model with detailed chemical reaction mechanism is adopted in KIVA program,three dimensional numerical simulation of DME PCCI-DI combustion is carried out.The computation result can accurately reflect the characteristics of DME PCCI-DI combustion and various components density changing situations in the cylinder.
