The system performance with different engine speed is studied in the paper, and the engine power, engine torque and fuel consumption is simulated through the engineperformancecurve.
通过发动机性能曲线，对发动机的功率、扭矩和燃料消耗量进行了模拟。

Then it analyzes the combustion characteristic of the LPG engine based on the curve of the heat release rate, and puts forward the measure of improving the performance of the LPG engine.
由生成的放热规律曲线分析了液化石油气发动机的燃烧特性，并提出了改善液化石油气发动机的性能的措施。
