Abstract：This paper introduces the role of reinforcing film in reducing vibration and noise on the intake side of the engine. Through comparative analysis， the intake manifold， bracket and oil duct were reinforced in turn. The results show that the reinforced film has the function of vibration and noise reduction， which provides a favorable analysis basis for NVH engineers to analyze the strength of each component. Support for subsequent engine development optimizations.

Key words：reinforcing film， engine， NVH test
