Appearance of damaged intake manifold

Automobile intake manifold mainly disperses the mixture of external gas and gasoline and diesel into the intake system of each cylinder according to carburetor or throttle body. The intake manifold is generally made of plastic, which will inevitably be damaged during the whole process of automobile use. The intake manifold will cause some problems, so let's take a look.

Main manifestations of intake manifold failure

If the intake manifold is damaged, air leakage will occur, and the air pressure will be reduced, which will further weaken the working capacity of the intake port, reduce the driving force of the engine, reduce the intake air and supply, and increase the carbon deposit. The cause of this situation is generally the cracking of the intake manifold, which will lead to air leakage. What is the manifestation of air leakage in intake manifold?

Main manifestations of air leakage in intake manifold

The air leakage of the intake manifold will cause sound, the car will vibrate, the idle speed will shake, it will not be able to speed up, it will be easy to stall, and serious cracking will also cause the car to be unable to drive.

Under all normal conditions, the air intake and air supply of the engine are certain. When the intake manifold leaks, it will lead to insufficient intake and gas supply of the engine, and the engine gasoline, diesel oil and gas can not be well mixed, resulting in insufficient driving force of the engine, which will lead to weak acceleration during driving. In addition, the air leakage of the intake manifold will also cause abnormal internal operation of the engine, engine fire, and engine exhaust pipe noise will also increase.
