Is it necessary to clean up the carbon deposit in the combustion chamber?

It is very necessary to clean up the carbon deposit in the combustion chamber with the Pacific car net. When carbon deposition is serious, it will change the original structural parameters of the engine, reduce engine power and increase fuel consumption. In severe cases, it will cause the engine to knock and make abnormal noise when accelerating, which will cause damage to the piston and crankshaft. Removing carbon deposits can avoid these problems well.

Because the engine cylinders are all injected with fuel first and then ignited, the ignition will be cut off immediately when the engine is turned off, but the gasoline ejected from this work cannot be recovered and can only be attached to the intake valve and the combustion chamber wall. Gasoline is very volatile, but the wax and gum in gasoline still exist. Over time, this layer of wax and gum will accumulate thicker and thicker, and repeated heating will form carbon deposits.

The method of cleaning carbon deposits can be machine washing, and many 4S shops and auto repair shops have products and equipment for cleaning combustion chambers. The cleaning agent is injected into a machine, and then sprayed into the combustion chamber by the machine under pressure, so that the cleaning agent reacts with the carbon deposit to dissolve, and then the waste liquid is pumped out. This method has a good effect on some cars with serious carbon deposits, and it is not necessary to disassemble the engine, but the cost is high, and the oil needs to be changed after cleaning.
