How does Audi c7 match the intake manifold? How did the Audi 2.5c7 intake branch pipe check that it was broken?

1. Vehicle intake manifold mainly disperses the mixture of outside air and fuel to the air intake of each cylinder through carburetor or throttle body. The intake manifold is generally plastic, which will inevitably be damaged during the use of the car, and the intake manifold will cause some failure problems.

2. Manifestations of intake manifold fracture: air leakage will occur when the intake manifold fracture, and the gas pressure will decrease, which will lead to the weakening of intake capacity, the reduction of engine power, insufficient intake air and the increase of carbon deposition. The reason for this is generally that the intake manifold is cracked, which will lead to air leakage.

3. Air leakage performance of the intake manifold: Air leakage of the intake manifold will make a sound, the car will shake, the idle speed will be unstable, the acceleration will be weak and it will easily turn off, and serious cracking will cause the car to fail to start.

4. In general, the air inlet of the engine is fixed. When the intake manifold leaks air, the air intake of the engine will be insufficient, and the perfect combination of engine fuel and air will not be formed, resulting in insufficient engine power, so there will be a situation of weak acceleration during driving. In addition, the air leakage of the intake manifold will also lead to abnormal internal working conditions of the engine, which will lead to the engine flameout and the noise of the engine exhaust pipe will also increase.
