Abstract: 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.
