摘　　要：本文采用一维三维耦合的方法,论证了双流道增压器不同结构形式对于发动机性能的影响,并结合试验结果验证了该方法的准确性,双流道增压器不同结构形式对于发动机的泵气损失有影响,泵气损失对于功率点的影响远大于对低速扭矩的影响。This article adopts the method of one-dimensional three-dimensional coupling,demonstrates the twin scroll turbocharger is the influence of different structure forms for engine performance,and combined with the experimental results verify the accuracy of the method,the twin scroll turbocharger to different structure forms have impact to engine pumping losses,pumping loss effects on power point is greater than the impact on the torque at low speed.

关 键 词：一维三维耦合 泵气损失 双流道增压器
