基于AVL的fire软件,对单缸汽油机改装的LPG发动机进行缸内燃烧过程的三维模拟计算。根据模拟计算结果,分析了LPG发动机均质混合稀薄燃烧条件、排放物的生成过程以及影响因素。模拟计算结果和分析对LPG发动机燃烧过程的完善提供了参考。
Based on the AVL fire software, the three-dimensional simulation calculation of the cylinder combustion process in a single cylinder gasoline engine modified LPG engine is carried out. According to the simulation results, the homogeneous mixed lean combustion conditions of LPG engine, the generation process of emission and the influencing factors were analyzed. The simulation results and analysis provide reference for the improvement of LPG engine combustion process.
