How to clean up engine carbon deposit?

Driving at high speed and increasing the shift speed of manual gear can effectively reduce the generation of carbon deposit, which will be beneficial to the erosion of air passage and inhibit the generation of carbon deposit. The same is true for increasing the shift speed, which can also effectively improve the power of the car, avoid knocking and better protect the engine. To reduce carbon deposition in engines, it is necessary to ensure high-quality gasoline. Because the formation of carbon deposit is mainly caused by wax, colloid and other substances in gasoline, I can effectively prevent the formation of carbon deposit by increasing the cleanliness of my car. Kaku auto network experts pointed out that the higher the gasoline label, the higher the cleanliness and purity of gasoline, and the selected oil label is only octane number. In order to avoid impure gasoline, you'd better choose a regular gas station to refuel. The most direct way to remove carbon deposits from the engine is disassembly and cleaning. At present, there is also a method of "disassembly and cleaning", but it is only effective for slight carbon deposition. If the engine has too much carbon, it still needs to be disassembled for cleaning. Relatively speaking, cleaning the valve carbon deposit is relatively simple, just remove the intake manifold and clean it manually. If the carbon deposit in the cylinder is cleaned, it will take a lot of effort, and the cylinder head and timing belt need to be removed and cleaned.
