| 摘 要： | 建立了火花点火式发动机的双区燃烧模型，其中包括化学动力学模型和湍流火焰燃烧模型．改进的双区燃烧模型中，区别于以往的绝热模型，考虑了已燃区向未燃区的传热．该模型通过模拟火花点火式发动机的燃烧过程，尝试性地进行了临界爆震预测和爆震分析工作．模型的计算结果与实验结果吻合得较好，验证了该模型分析的可行性．

| Abstract: | A two-zone combustion modeling in spark ignition(SI) engine that includes chemical kinetic modeling and turbulent flame combustion modeling was established. Heat transmitting from burned zone to unburned zone was considered in this combustion modeling. The combustion process and critical knock can be simulated in this modeling. It is shown that the calculated results are in good agreement with the data from cylinder pressure measurements. |
