Is it necessary to clean up the engine carbon deposit?

Carbon deposition is a kind of combustion substance produced by unsaturated olefins and gums in fuel at high temperature during engine operation. It needs to be cleaned regularly. The main parts of cleaning are: cleaning the throttle, cleaning the carbon deposit inside the engine, cleaning the carbon deposit in the oil circuit and cleaning the carbon deposit in the intake system. Only in this way can the vehicle run better.

Cleaning suggestion

1, throttle carbon cleaning.

The throttle is the throat of the engine. Breathing smoothly depends on the throttle valve. Under normal circumstances, the cleaning cycle of the throttle valve is about 20,000 kilometers. The throttle valve must be cleaned regularly. If the engine shakes badly, it needs to be cleaned immediately.

2, the engine internal sludge cleaning

It is usually done during maintenance. Professional cleaning agents or clean engine oil must be used. After pumping out the old engine oil, pour the clean engine oil into the engine, cover the engine oil cover, turn off the engine after idling for 10 minutes, and then replace it with new engine oil. Cleaning agent can dissolve sludge, colloid, moisture, metal chips and other deposits in the engine, which can reduce the pollution of new engine oil and prolong the service life of the engine. Usually 30 thousand kilometers or once a year to clean the engine.

3, oil carbon cleaning

Cleaning the carbon deposit in the oil circuit generally includes cleaning the fuel injector, combustion chamber, spark plug and throttle. The purpose of cleaning up the carbon deposit in the oil circuit is to solve the problems of insufficient horsepower, increased fuel consumption, abnormal jitter, poor acceleration and difficult start-up caused by carbon deposit, colloid and dirt in the oil circuit system. Usually it can be cleaned once a year.

4. Removal of carbon deposit in air intake system

Cleaning the carbon deposit in the air intake system mainly refers to cleaning the carbon deposit in the air intake and air intake pipe. The purpose of cleaning the carbon deposit in the intake system is to remove the carbon deposit in the intake system, increase the intake flow and speed, and reduce the engine jitter and unstable idle speed. Generally, it is enough to do a cleaning once every 60,000 kilometers.
