摘要
针对发动机进气谐振器容积会对发动机的进气性能产生重要影响这一问题,利用AVL-BOOST软件建立了汽油机的仿真模型,并详细介绍了该模型的建立过程。根据所建立的模型,通过改变谐振器的容积,在不同的转速下进行了发动机的仿真计算,最后进行了比较和分析计算。研究结果表明,谐振器的容积对发动机进气性能有很大影响,通过适当改变谐振器容积最多可以提高原机1.4%的充量系数;针对这款480发动机,谐振器容积最好选择在0.6 L^1.0 L之间;不同的机型还需要通过计算合理进行选择。
Aiming at the volume of an intake resonator had a great effect on the volumetric efficiency of the engine,simulation model of gasoline engine was built up by using AVL-BOSST software. And the established process of the model was introduced in detail. According to the established model,simulation was run by changing the volume of the resonator at different rotational speed of engine. Finally the comparing and analyzing were made. The results indicate that the size of the volume of resonator has very important influence on the inlet performance,the original machine charge coefficient can be increased up to 1. 4% by appropriate changes in the resonator volume. For the 480 gasoline engine,the volume of resonator had better choose between 0. 6 L to 1. 0 L. Different models need to be calculated according to the reasonable choice.
