Analysis of Mixture Formation and Combustion Process in a DISC Engine

다국어 초록 (Multilingual Abstract)

In this report, the author has, briefly introduced research summary on the stratified charge combustion system that has a possibility of simultaneous reduction of exhaust emissions and fuel' consumption rate. Firstly, the effect of spatial distribution of mixture stratification on combustion characteristics was investigated using a constant volume chamber. Secondly, the break-up process of fuel spray was examined to control the mixture formation process. Thirdly, turbulence and combustion modeling was discussed as a tool to clarify the physical phenomena. Finally, a model GDI engine was employed to evaluate a new concept.
