Abstract: In recent years, the three-cylinder engine has been widely used in various brands of cars in the market. The three-cylinder engine brings many advantages to the vehicle, but also brings some negative effects. This paper mainly discusses the relationship between the three-cylinder engine and NVH, the impact of the structure characteristics of the three-cylinder engine and its balance on NVH, and gives effective solutions to the jitter problem of the three-cylinder engine by analyzing specific cases.

Key words: Engine(three cylinder); Shake; NVH; Balance

摘要： 近年来市场上三缸发动机广泛应用在各品牌汽车上，三缸发动机为整车带来很多优势的同时，也带来了一 些负面的影响。文章主要论述发动机三缸机与 NVH 的关系，三缸机的结构特点及其平衡性对 NVH 的影响，通 过具体案例进行分析，针对三缸发动机易出现抖动问题给出有效的解决措施。
