AIM是air intake manifold缩写,是汽车发动机上的部件,以前主要使用铝压铸制作,现在国外已经掌握了成熟的注塑制作方法。目前主要有两种方法生产:震动焊接和熔芯法(lost core)。
由于比较复杂、技术含量比较高,所以目前仍处于保密阶段,在网上很难找到相关的信息。目前国内也只有几家公司做过这样的模具,但成品基本上都是国外公司生产的。由于中国汽车市场的迅猛增长,现在好几家公司也在中国投资,本人现在正是在其中的一家,因此想找一下有没有这方面经验的朋友,一起交流学习!
The main function of an intake manifold is to distribute clean air – as far as possible, without pressure loss – from the air filter into the combustion chamber. As well as the throttle body, further components such as an air mass meter, sensors, EGR ducts, fuel rail and injection valves are integrated into the unit.
The performance and torque of combustion engines have been significantly improved through the develOPMent of variable air intake manifolds which can switch between different runner lengths. A short runner optimises performance at higher speeds, whilst a long runner provides favourable torque in the lower and medium speed ranges.
