Intake system of engine is one of the main noise sources of an automobile. In this paper, the acoustic transmission loss of the engine intake system was simulated by CAE, and the defects in its noise silencing were found. With the use of perforated muffler, the intake system was optimized. The defects in the noise silencing were removed and a favorite effect was reached.
