摘　　要：笔者利用GT-power软件对某1.3L4缸汽油发动机进行研究,提出了并联式一涡两压单轴两级涡轮增压器的概念,建立了两级增压流通仿真模型,进而进行了结构设计与样机试制。测试结果表明,此增压器在功率、扭矩及油耗等方面相对常规单机增压有显著优势。In the present paper, the concept of a 1.3L-4 cylinder gasoline engine is studied by using GT-power software, and the two-stage turbocharger of one-turbo two--compressor single-axis is established. The structure design and the prototype are carded out. The test results show that the turbocharger has significant advantages in terms of oower, toroue and fuel consumption.
