The multi-area model and application to combustion process in gasoline engines

Combustion modeling is a very important method in designing internal combustion engine. In this paper, a multi-zone one with diagnostic and predictive functions is proposed for combustion in a gasoline engine. This model has 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.
