Excuse me, how to deal with excessive carbon deposition in Jetta engine?

First, understand what is carbon deposit: the substance left in the fuel nozzle, throttle, oil pipe, spark plug, cylinder head, inner wall and other parts due to insufficient combustion of gasoline in the cylinder, and then the black colloid produced by repeated high temperature of the engine is called carbon deposit.

The harm of carbon deposit to automobile engine, if carbon deposit is not cleaned for a long time, it will cause the power of automobile engine to decrease, fuel consumption to decrease, abnormal engine noise and unstable idle speed.

If it is a new car, the engine power is insufficient and the fuel consumption is high, it is suggested to clean the throttle or make a car endoscope to see if it is caused by carbon deposition.

If it is an old car, it has run more than 654.38+ 10,000 kilometers, and you can choose to hang the bottle (cleaning agent) or open it for cleaning. It is recommended to use suspended cylinders to clean up carbon deposits. One thing is not to disassemble any parts of the engine, which will not cause engine damage. Disassembly and cleaning require disassembly of engine parts. After all, it has been dismantled, and there will be no other faults in the engine in the future, and the risk will be greater.
