How often do you decarbonize the engine? Seek answers from auto maintenance experts.

Generally, it can be cleaned once every 2-4 weeks.

Engine carbon deposit: a kind of combustion substance produced by unsaturated olefins and gums in fuel at high temperature during engine operation.

Hazards of carbon deposition: Carbon deposition has a great influence on vehicles, which will reduce engine power and increase fuel consumption. In severe cases, it will also cause the engine to knock, accelerate abnormal sound, cause damage to the piston and crankshaft, and even eventually lead to the engine burning oil and needing overhaul. Carbon deposition is not only harmful to cars, but also harmful to the environment. Can directly affect the automobile exhaust emissions, resulting in failure to pass the annual inspection. So we need to pay attention to the problem of carbon deposition, and we can't turn a blind eye.

Cleaning steps:

Clean throttle valve

Clean the carbon deposit inside the engine.

Removing carbon deposit in oil circuit

Remove carbon deposits in the air intake system.

How to judge whether the engine should clean up carbon deposits;

When the engine is working, the sound is stuffy, the exhaust is not smooth, the idle speed is unstable, the work is weak, the oil consumption increases, the water temperature and exhaust temperature rise abnormally, it is difficult to start, and the throttle is not sensitive. All these phenomena are related to carbon deposition. However, it should be specially reminded that in order to get a correct judgment, we must eliminate the faults related to the above phenomena before we can draw a conclusion, because as we all know, some phenomena reflected by different faults are the same, so we need to eliminate them one by one.
