由于传统的进气歧管设计往往要按照发动机的具体要求,或者按照高转速的要求设计,或者按照低转速的要求设计,再或者采用折中的办法,但是无论哪种设计,都不能兼顾不同转速时的需求,这时可变进气歧管应运而生,能够适应不同的发动机转速要求。文中对某型可变进气歧管进行仿真分析,分析其在不同工况下的进气均匀性是否满足设计要求。
Because traditional intake manifold design often according to the specific requirements of the engine, or in accordance with the requirements of high speed design, or in accordance with the requirements of low speed design, or compromise, but no matter what kind of design, can not take into account different When the speed of demand, when the variable intake manifold came into being, able to adapt to different engine speed requirements. In this paper, a certain type of variable intake manifold simulation analysis to analyze whether the intake uniformity under different conditions to meet the design requirements.
