根据直喷式四冲程柴油机的工作特点,结合传统柴油机的燃烧模型,建立适合于二甲醚发动机的燃烧模型,并进行模拟计算。模拟结果与试验结果比较吻合,表明该模型具有一定的适用性。
According to the working characteristics of direct injection four-stroke diesel engine and the combustion model of traditional diesel engine, a combustion model suitable for dimethyl ether engine is established and simulated. The simulation results are in good agreement with the experimental results, indicating that the model has some applicability.
