1. Oil leakage. This is generally the case that the shaft seal of the turbocharger exhaust gas is damaged, and the oil will enter the fresh air from the oil seal, thus entering the engine cylinder. In other words, the oil burned. If the supercharger is removed at this time, it will be found that the shaft is full of coking, which is the residual of the dry burning oil. For car owners, burning oil, smoking blue smoke, these should be understood.
2. The engine oil system problem caused the supercharger problem. For example, the oil filter fails and dirty oil enters the system. The turbocharger of the shaft, hundreds of thousands of speed, oil seal all rely on clearance with, is a very precise thing.
3. Problems caused by air intake problems. For example, the air filter is damaged, and large particles enter the air channel. As said in front, the impeller will be broken when it rotates at high speed.
4. The supercharger itself mechanical problems. Mainly pressure limiting valve, also known as pressure relief valve and so on. Is the supercharger internal pressure is too large, will take the initiative to open the one-way valve. If this valve is broken, there will be strong engine shake and other problems at high engine speed, you can feel it immediately.
