A auasi-phenomenon multi-zone spray combustion model and for DI diesel engine

Abstract

According to the idea that the formation of combustible mixture and combustion process controlled by the distributing states of fuel and air, a quasi\|phenomenon multi\|zone spray combustion model and soot prediction submodel for DI(direst injection). diesel engine are built up. The flame temperature and soot concentration are fairly good predicted by using the model, and the computed model provides good parameters for research of heat radiation transfer in DI diesel engines.
