火花点火天然气发动机工作过程的数值模拟

Numerical Simulation of Working Process of Spark Ignition Natural Gas Engines

近年来,由于能源和环保的要求,火花点火天然气发动机以高效、低污染燃烧的优点正在迅速发展。为了分析和研究这种发动机的运行特性,预测多种参数变化对性能的影响,将零维模型应用于气体燃料发动机燃烧过程中。试验表明,模型的计算值和试验值具有很好的一致性。模拟计算弥补了实验测试中的不足,可以从更深层次地认识气体燃料发动机的运行特性和规律。

In the near future, spark ignition engines have rapid progress depending on their high efficiency and low pollution for the requirement of energy source and environmentalism. In order to analyse and research their runtime characteristic, forecast the infection of many parameters, the zero-dimension model is applied. It is indicated through experiment that the result of this model and test are consistent. The numerical simulation makes up the deficiency of experiment and deeply understands the runtime characteristics, rules of gas engine.
