How to clean the engine carbon deposit?

The platform has also expressed its views on pulling the expressway before. Running high-speed and pulling high-speed often can slow down the formation of carbon deposits, and at most can wash away newly generated carbon deposits, which has little effect on cleaning up carbon deposits that have been generated for a long time. However, most riders still say that pulling the expressway can clean up carbon deposits, so this is also a kind.

Second, disintegration and cleaning.

The advantage is thorough cleaning, but the disadvantage is that it is often difficult to achieve the assembly accuracy of the original factory. Even if all the load-bearing fasteners such as bolts and gaskets are replaced, the engine performance will be affected to some extent. Therefore, unless the carbon deposition is very serious and cannot be solved by other means, the engine has to be disassembled to solve it. In addition, choose carefully!

III. Cleaning of infusion bags or bottles

At present, the most commonly used disassembly-free cleaning method is similar to human intravenous drip, so this cleaning method is named, which is also commonly known as "intravenous drip" and "infusion bottle"

Four, fuel system cleaning agent (directly added to the fuel tank)

The advantage is that the method is simple and easy to operate. Just add a proper amount of additives and gasoline into the fuel tank to protect the "heart" and clean the "intestines" of the car at any time and place, which can not only remove carbon deposits, but also improve oil products and prevent the formation of carbon deposits and colloid. The disadvantage is that the quality of fuel additives is uneven at present, and the fishy eye is mixed. Some have no effect at all, and some contain metal components, which are harmful to cars.

Five, walnut sand cleaning carbon deposit

Walnut sand is a fine particle made of walnut shell after processing. The principle of removing carbon deposits by walnut sand is to put walnut sand into equipment and use compressed air as power. The working pressure is established in the pressure box by compressed air, and the walnut sand is pressed into the sand conveying pipe by sand cutting, and sprayed at a high speed at the nozzle and into the air inlet of the engine. Because the valve of the cylinder has been closed before cleaning, the high-speed walnut sand will collide and scrape in the closed air passage, so that the carbon deposit on the valve and the air inlet will be knocked open and washed down. Finally, the walnut sand and the carbon deposit will be sucked out by the suction device provided by the equipment, so as to achieve the purpose of cleaning up the carbon deposit.
