【Abstract】 In this paper, a mathematical model of combustion process for the gasoline rotary combustion engine was developed. The turbulent flame propagation model of a reciprocating piston gasoline engine was inspected to see whether it is applicable to gasoline Wankle engine based on the experimental data. The modified turbulent flame propagation model was established for predicting cylinder pressure and indicated mean effective pressure of the spark-ignition rotary engine. The study showed the correctness of the combustion process model and the modified flame propagation formula can be used to simulate the performance of gasoline rotary engine.更多还原
