建立了汽油机燃烧过程的双区和多区诊断及预测模型，其中包括火焰传播模型。在质量燃烧率的 计算中，直接反映了紊流对燃烧过程的影响。编制了计算程序，进行了计算与试验的对比分析，计算结果 与试验结果两者吻合良好。同时进行了变参数性能预测计算。
A dual-zone and multi-zone diagnosis and prediction model for gasoline engine combustion process is established, including flame propagation model. The calculation of the mass burn rate directly reflects the influence of turbulence on the combustion process. The calculation program is compiled, and the comparative analysis of calculation and experiment is carried out. The calculation results are in good agreement with the test results. At the same time, variable parameter performance prediction calculation.
