摘　　要：为了提高发动机的性能及降低油耗,并且更好地做到发动机小型化-三缸机,现在很多发动机采用48 V轻混系统。三缸发动机的动力总成搭载48 V轻混系统,可以在启动工况及加速工况中降低发动机转速波动及降低发动机附件系统张力和波动。三缸机动力总成搭载48 V轻混系统会搭配解耦器系统,但是随之会带来一定的噪声问题。In order to increase the engine performance and reduce fuel consumption,and make the engine smaller,many engines use 48V light hybrid system.The powertrain of three cylinder engine is equipped with 48V light hybrid system in order to reduce the fluctuation of engine speed,the tension of engine accessory system and the fluctuation of system tension in starting and acceleration condition.The powertrain of three cylinder engine equipped with the 48V light hybrid system should be equipped with decoupling system,but it will bring some noise problems.

关 键 词：发动机 BSG电机 解耦器系统 噪声
