在介绍汽油机射流燃烧室过程的三区燃烧模型的基础上，与计算焰前氧化放热过程的简化化学动力学模型相结合，对射流燃烧室爆震进行了预测。通过燃烧模拟计算进一步证明了射流燃烧室的优越性，并为进一步研究燃烧过程提供了有效的工具。 Based on the three-zone combustion model of gasoline engine jet combustor and the simplified chemical kinetic model for calculating the exothermic oxidation process, the jet combustor detonation was predicted. The combustion simulation calculation further proves the superiority of the jet combustion chamber and provides an effective tool for further study on the combustion process.
