Is it necessary to clean the carbon deposit in the intake valve?

Clean up the carbon deposit in the intake valve every 20,000-30,000 kilometers.

Never spray a large area of accelerator cleaner and wipe it hard, which will do great harm to the accelerator. After cleaning the throttle, use the computer to cooperate, so that the control of the throttle by the computer can be restored to its original state.

The hazards of carbon deposition in the intake valve are as follows:

1. When carbon deposits are attached to the exhaust valve, the intake and exhaust valves are not tightly closed, resulting in air leakage and pressure drop in the engine cylinder. As a direct result, it is difficult to start the engine, and jitter occurs at idle speed, which also affects the cross section of the mixture entering the combustion chamber. Carbon deposition will adsorb a certain amount of mixed gas, thus reducing engine power.

2. When the carbon deposits are attached to the cylinder and piston crown, the volume (space) of the combustion chamber will decrease and the compression ratio of the cylinder will increase. If the compression ratio is too high, the engine will burn ahead of time (the engine will knock) and the power of the engine will be reduced.

3. When carbon is attached to the spark plug, it will affect the quality of the spark and even not catch fire.

4. When carbon deposits are formed between piston rings, the piston rings are easily stuck, resulting in deformation of engine oil and cylinder wall.
