本文以氢燃料发动机的试验结果为基础，分析了氢燃料发动机的预燃和从预燃到回火的转变过程。通过对链式反应的分析，研究了氢燃料发动机的预燃和回火机理。分析表明，温度、压力和压力升高率对预燃和回火有很大影响。并根据放热率的热力学关系，对预燃和回火进行了分析。最后，建立了多变量、多目标、多约束的优化控制模型。并通过遗传算法进行了仿真。结果表明，可以通过加权系数来调整过量空气系数和点火提前角，从而优化功率输出，抑制异常燃烧。从而为解决制约氢燃料发动机异常燃烧与提高发动机功率输出之间的矛盾提供了一种有效的方法。
In this paper, based on experiment result in a hydrogen fueled engine, pre-ignition and transforming process from pre-ignition to backfire of the hydrogen fueled engine was analyzed. Moreover, mechanism of pre-ignition and backfire of hydrogen fueled engines was studied by analyzing chain reaction. The analysis shows that the temperature, pressure and rate of pressure rise have great influence on pre-ignition and backfire. And based on thermodynamic relations of heat release rate, both pre-ignition and backfire were also analyzed. Finally, optimization control model which has multi-variables, multi-objectives and multi-constraints was established. And the simulation was carried out through the genetic algorithm. Results have shown that the excess air ratio and ignition advance angle can be adjusted by weighted coefficients to optimize the power output and restrict the abnormal combustion. Thus, a useful method is shown to resolve the contradictions between restricting the abnormal combustion and improving hydrogen fueled engine’s power output.
