How to clean the carbon deposit in the cylinder of in-cylinder direct injection engine

The removal method of carbon deposit in in-cylinder direct injection engine is as follows:

Bottle hanging: firstly, prepare a hanging bottle, hang the hanging bottle above the engine, then add the cleaning agent into the bottle, and transport the cleaning agent into the engine through the connected conduit to clean up the carbon deposit; This method of cleaning up carbon deposits is commonly used, and the price is about 800~ 1000 yuan, but this method is not suitable for serious carbon deposits.

Machine washing: put the prepared cleaning agent into a special cleaning machine, and then start the machine to work. The cleaning agent will enter the engine to slowly dissolve the carbon deposit, and then the waste liquid will be pumped out after dissolution; This method is suitable for serious carbon deposition, but the price is relatively expensive, which needs about 1000 yuan.

In order to reduce the carbon deposition produced by direct injection engine, better fuel can be added; One of the biggest reasons for carbon deposition is poor fuel quality. Once there are impurities in it, it will lead to carbon deposition. You can choose better gasoline and try to avoid idling.
