摘要：把柴油/天然气双燃料发动机工作过程分成七个阶段:压缩阶段、滞燃期阶段、燃烧阶段、纯排气阶段、进排气阶段、纯进气阶段,建立了每个阶段的数学模型,燃烧过程用三个Wiebe函数来描述。在Matlab下的Simulink环境中建立发动机工作过程的仿真模型进行模拟,将仿真数据与试验数据进行对比,发现该模型的仿真结果与试验数据相吻合。
The performance of Diesel-CNG dual fuel engine was divided into seven phases, which are compression phase, ignition delay phase, combus- tion phase, pure exhaust phase, intake-exhaust phase, pure intake phase, and the mathematical model of each phase was established. The combustion process was described by three wiebe function. The simulation model of the working process was simulated in Simulink of Matlab, and the data was then compared with the test data, which shows they are well consistent with each other.
