A New Approach to Simulation of Combustion in Gasoline Engines

Combustion modeling is a very important method in designing internal combustion engine. In this paper, a two-zone model and also a multi-zone one with diagnostic and predictive functions are proposed for combustion in a gasoline engine. These models have been used to predict the performances and their changing with variable parameters such as ignition advance angle and coefficient of the residual exhaust gas respectively, in a BJ492Q gasoline engine. All the results of these calculations have been compared with experimental measurements. The results show that the proposed models are very valid and effective.
