| 摘 要： | 介绍了数值模拟技术在发动机研究过程中的重要作用,以捷达前卫发动机为基础,应用GT-POWER软件建立了发动机工作过程模型,通过实验验证了该模型的可靠性.在此基础上对配气正时进行了模拟计算,计算结果表明在高转速时适当增大进气迟闭角对提高发动机的性能有利,与理论分析一致.

| Abstract: | In this paper the importance of numerical simulation in the process of engine study was introduced.Based on the Jetta a model of engine was established with the GT-POWER software.The reliability of the model was tested by experiment.Based on the result we carried a variable parameters study on the valve timing.The result showed that increasing the inlet valve close timing probably would have a good to engine performance which was consist with theoretical analysis. |
