Abstract With the increase of automotive comfort need， the requirement of acoustic performance of the engine's intake system is increasing. Based on acoustic theory， the numerical model with multi-parameter of air cleaner of mini gasoline engine was built. On the one hand， through simulation of the noise of mini gasoline engine's straight pipe orifice， the target value of intake system's insert loss was gotten; on the other hand， considering the target value of insert loss， the target value of transfer loss of mini gasoline engine's intake system was estimated. By associating with air cleaner's acoustic numerical model， air cleaner's structure parameters were optimized. The design method of acoustic performance of mini gasoline engine's intake system has great practical engineering significance， and the numerical model with multi'parameter provides theoretical basis for parameter design of air cleaners of mini gasoline engine．
