Abstract

In order to investigate the influence of combustion chamber geometry on the formation of air-fuel mixture in diesel engine, a new double-layer diffluent combustion system for DI diesel engine was proposed which had a collision platform with circular oriented-surface. The mixing process of the fuel spray and air in this combustion chamber is modelled and numerical simulation is executed by the software AVL FIRE. The simulation results indicate that the fuel spray distribution becomes more uniformed for the double-layer diffluent combustion system than that of the combustion system. It can be concluded that the combustion chamber geometry put important effect on the formation of air-fuel mixture in combustion chamber.
