Common Faults Of Turbocharger

Generally, turbocharger has four kinds of faults. They are oil leakage, compressor surge, excessive noise and overheated.

The reason of leakage are various. Such as the oil is not clean, the solid particle polluted seriously, poor quality or low grade oil, oil supply shortage or low oil pressure, the oil inlet pressure is too high, the air filter is clogged and others. If you have met this problem, you should check your engine speed. If the engine idling time is too long, you should improve the speed. If the import hydraulic booster is too high or too low, you should check the oil level. Add or replace the  eligible oil if it is necessary. If the oil pressure display normal, you should check the oil return channel turbocharger is smooth. Clean air filter, then dredge and clean diesel engine crankcase ventilation device.

The reason of excessive noise is also various. The leak noise because of the connection or the seal is not good. If there is foreign body entered, it may cause damage to the turbine or compress or impeller blade. Movement change of gas will make the supercharger vibration strongly. If you have met this problem, you should check the air filter without obstruction, whether foreign body have entered to the compressor inlet pipe or compressor casing, exhaust system of diesel engine. Diesel engine intake or exhaust pipe is loose and clean up or fastening.
