Plastic intake manifold light weight, low material and manufacturing costs, smooth wall, the air flow resistance can be reduced

Plastic intake manifold light weight , low material and manufacturing costs , smooth wall , the air flow resistance can be reduced to improve engine performance , economy and emissions improvement . Currently , gasoline plastic intake manifold design technology has matured , the country already independent research and mass production, while diesel plastic intake manifold design is still in its infancy. Plastic instead of metal as a car engine intake manifold material , the intake manifold is the trend of the development lies. However, in the design and  Instrument manifolds  of the intake manifold , the assembly of the research is the development process is often overlooked issue. This article will be mounted design ideas throughout the plastic intake manifold design is always , can be assembled primarily through the design and evaluation , research and analysis of the plastic intake manifold can be assembled . First, the structure and  Stainless steel needle valve  the engine and the intake manifold is analyzed . Followed by the assembly from the engine , and the engine intake manifold assembly , the assembly and maintenance of four intake manifold intake manifold accessories detailed analysis of the engine intake manifold assembly process and assembly difficulty. Explore again from the subsidiary parts, assembly sequence , ergonomics and summarizes the evaluation of three engine intake manifold assembly of quality standards and principles , focusing on human-computer engineering from the engine intake manifold assembly were studied .
