How to distinguish engine intake hose intake manifold:

  The intake manifold is also known as the intake manifold. The intake manifold separates the lines of the N pipes (depending on the number of engine cylinders).

  The main function of intake manifold is to meet the function of single intake of each multi cylinder.

  The intake manifold is located between the throttle the engine intake valve. It is called "manifold" because the air flow path "diverges" here after the intake air enters the throttle after the manifold damping system. For example, corresponding to the number of engine cylinders, a four cylinder engine has four channels, a five cylinder engine has five channels, which respectively introduce air into each cylinder. For a naturally aspirated engine, since the intake manifold is located behind the throttle, when the throttle opening of the engine is small, enough air cannot be drawn into the cylinder, which will result in a high vacuum degree of the manifold; when the throttle opening of the engine is large, ZD will reduce the vacuum degree of the intake manifold. Therefore, the injection fuel supply engine will install a pressure gauge on the intake manifold to supply the ECU to determine the engine load provide the appropriate equivalent fuel injection
