摘　　要：混动车用发动机的运行工况与常规燃油车相比变化是非常明显的,发动机承担主要动力源的角色也在发生转变。在这一系列的变化中寻找降本的优化路线,同时也需要预防由此产生新的失效问题。结合目前市场上应用效果较好的两款混动架构阐述混动发动机主要变化特点及潜在的失效问题。The difference between the operating condition of the engine of the motor vehicle and that of the conventional fuel vehicle is very obvious,and the role of the engine as the main power source is also changing.In this series of changes,the optimization route of cost reduction is sought,at the same time,it is also necessary to prevent the resulting new failure problems.This paper expounds the main changing characteristics and potential failure problems of hybrid engines by combining two hybrid architectures with good application effects in the current market.
