Is it necessary to clean up the carbon deposits in automobile engines? Is it necessary to remove carbon deposits in engine cylinders? It is necessary to remove carbon deposits from the engine. The engine of an ordinary car needs to be cleaned once when it travels about 30 thousand kilometers. The existing technology can't make gasoline burn completely, so as long as the engine is running, carbon deposition will occur. The main positions of carbon deposition are: combustion chamber, intake valve and its surroundings, three-way catalyst, lubrication system, etc. Throttle is a device to control air intake near the top of combustion system. Due to the working environment and nature of the throttle valve, carbon deposits may form on this part. The common cleaning method for cleaning the throttle carbon deposit is to remove the throttle, clean the throttle with carburetor before and after, and wipe off the decomposed carbon deposit with cotton cloth.
