摘要
利用GT-Power软件建立了汽油机与其排气系统的耦合模型,模拟分析主消声器和副消声器的结构对排气噪声、发动机性能以及排气系统参数的影响。最后,根据模拟结果,选择合适的主消声器和副消声器的结构形式,设计出性能优越的排气系统。
By using software GT-Power,a coupled model for gasoline engine and its exhaust system is built and the effects of primary and secondary muffler configurations on exhaust noise,engine performance and the parameters of exhaust system are simulated and analyzed.Based on the results of simulation,the appropriate configurations of primary and secondary muffles are finally chosen and an exhaust system with good performance is designed.
