Auto engine intake

August 09, 2022

The intake manifold refers to the intake pipeline from the rear of the carburetor or throttle body to the front of the cylinder head intake duct. Its function is to distribute the air and fuel mixture from the carburetor or throttle body to the intake ports of each cylinder. The design of the intake manifold is also highly knowledgeable. In order for the combustion conditions of each cylinder in the engine to be the same, the length and curvature of the manifold in each cylinder should be as consistent as possible.

Due to the fact that the engine operates through four strokes, each cylinder of the engine is injected in a pulse manner. Based on experience, longer manifolds are suitable for low speed operation, while shorter manifolds are suitable for high speed operation. So some car models will use variable length intake manifolds or continuously variable length intake manifolds to enable the engine to perform better in various speed ranges. The plasticization of engine intake manifolds is a trend in the development of automotive engine intake manifolds. Plastic intake manifolds have significant advantages over traditional aluminum intake manifolds.

The main advantages of plastic intake manifolds are lower cost and lighter weight. In addition, due to the lower thermal conductivity of PA compared to aluminum, the temperature of the fuel nozzle and incoming air is lower. Not only can it improve hot start performance, increase engine power and torque, but also during cold start, it can to some extent avoid heat loss in the pipe and accelerate the increase of gas temperature. Moreover, the inner wall of the plastic intake manifold is smooth, which can reduce air flow resistance, thereby improving engine performance. In terms of cost, the material cost of plastic intake manifolds is basically the same as that of aluminum intake manifolds. Plastic intake manifolds are formed in one go, with a high qualification rate; However, the casting yield of aluminum intake manifold blanks is low and the machining cost is relatively high, so the production cost of plastic intake manifold can be reduced by 20% -35% compared to aluminum intake manifold.

The intake manifold is a key component that supports engine operation, with a complex structure and high requirements for mold structure and quality.
