| Abstract: | The paper introduces a phenomenon that the power is deficiency when the car accelerating is done in one Audi A41.8T car manufactured in 2004;and proceeds a routine trouble shooting and date diagnose.Based on introduction of the working principle of the exhaust-gas turbocharger system of Audi1.8T engine;it indicates that the reason of the engine air input decrease and decay of power is because of the boost pressure deficiency.The article finally concludes a tip on the exhaust-gas turbocharger system repairing and debugging. |
