What's wrong with the exhaust turbine of Mercedes-Benz C200?
Prevent inhalation. ) If the flame is turned off instantly, check back from the intake pipe and find the intake filter element. If you block the throttle by hand, clamp the two small tubes on the air branch pipe with pliers, usually the lower tube, and the upper tube is generally fine. When doing this, don't take the throttle lever away. It's better to have two people. If the engine is turned off and the one-way valve from the exhaust pipe to the intake branch pipe is broken, it will be normal to replace the engine with a new one, and the fault can be cleared.
Reason:
1. Whether the negative pressure at the air inlet of the supercharger is too large is generally caused by the blockage of the empty filter screen. The air filter is seriously blocked, resulting in a decrease in the amount of fresh air entering the engine and a decrease in the boost pressure.
2. If there is no problem in the first item, check whether the connecting pipe from the supercharger outlet to the engine throttle leaks. If there is air leakage, it will directly lead to insufficient pressure and pressure drop.
3. Check the engine exhaust manifold pipe joint for air leakage. If there is air leakage, it shows that the energy loss of turbine will directly lead to the energy loss of compressor end. Another point is to check whether the supercharger is scratched. These failures will cause the pressure from the supercharger to the throttle to be too low.
