How many kilometers does Accord clean up the engine carbon deposit?

It depends on the oil used, road conditions, etc. Generally, the engine carbon deposit is cleaned once every 20,000 kilometers. Carbon deposition will affect the performance and life of the engine, so it is recommended to clean it regularly.

Carbon deposit is the carbon deposit of the engine: when the engine is working, unsaturated olefins and gums in the fuel are a kind of combustion products produced at high temperature.

Methods to prevent formation

First, idling for a long time can easily lead to the formation of carbon deposits in automobiles.

When the car is idling, less air enters the engine, which makes the air flow smaller and makes it easy for the car to form carbon deposits faster.

Second, use car cleaner to reduce the formation of carbon deposits in cars.

The formation of automobile carbon deposit is due to some impurities in gasoline. If you use gasoline with higher cleanliness, there will be less carbon deposition in the car. If you use some car cleaner, you can activate carbon particles formed on the metal surface.

Third, clean the air intake system of the car regularly.

It is the most effective way to reduce the formation of carbon deposits to do some necessary cleaning on the air intake system of the car, so the owner can do some necessary cleaning on the air intake system of the car about 30 thousand kilometers.
