| 摘 要： | 建立了汽油转子发动机燃烧过程的数学模型；基于实验数据，考察了往复式汽油机湍流燃烧速率计算经验式在汽油转子发动机中应用的不适用性，并对其进行了修正；将建立的燃烧模型和修正后的湍流燃烧速率计算公式用于预测汽油转子发动机燃烧室内气体压力和平均指示压力，预测与测量结果基本吻合。结果表明：建立的汽油转子发动机燃烧过程数学模型和修正后的湍流燃烧速率计算公式准确，可用于汽油转子发动机性能模拟研究。

| 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 modifled 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. |
