The Ingenious Design Of The Intake Manifold

- Mar 08, 2019-

The design of the intake manifold is also very learned, in order to the engine each cylinder combustion condition is the same, each cylinder of the manifold length and bending degree should be the same as possible. Since the engine is operated by four itineraries, each cylinder of the engine will enter the gas in a pulse mode, according to experience, the longer manifold is suitable for low speed operation, while the shorter manifold is suitable for high speed operation.

Therefore, some models will use variable-length intake manifold, or continuous variable length intake manifold, so that the engine in each speed field can play a better performance.
