摘要
阐述了数值模拟技术在发动机研究中的重要作用,应用GT-POWER软件建立发动机燃烧乙醇汽油的工作过程模型,通过发动机台架试验验证模型的可靠性,在此基础上应用该模型对发动机的工作过程进行模拟计算,研究了发动机转速对发动机性能的影响,并对点火提前角进行优化计算,确定点火提前角对发动机性能的影响。
The important role of simulation technology on engine study was introduced in this paper.The working process model of the engine burned with ethanol-gasoline was established and the reliability of the model was tested by experiment.The working process was simulated based on the model to study the effects of engine speed to engine performance.The spar-king angle was optimized to determine its effects to engine performance.
