| 摘 要： | 发动机进气系统是发动机的重要组成部分，进气系统性能的好坏严重影响发动机和整车性能。文章利用GT—Powe，软件，以4100型汽油机为原型机进行一维建模仿真，介绍了不同进气总管管长和管径在发动机不同转速时对充气效率、扭矩及功率的影响。表明进气总管结构参数主要影响进气系统波动效应，提出发动机在中低转速时对充气效率影响较大；而高转速时，对充气效率、发动机扭矩和功率的影响较小。对汽油机进气系统的优化设计具有一定的借鉴意义。

| Abstract: | The intake system is an important part of the engine. The performance of the intake system impacts on the engine and vehicle performances. Based on the GT -Power software and taking 4100 engine as the prototype, a one -dimensional modeling is presented. And the affects on volume efficiency, torque and power with different length and diameter of intake pipe is introduced. It is indicated that structure parameters of intake pipe mainly influences the flutter of air intake system. And it has greater influence ... |
