Is throttle cleaning the same as engine cleaning carbon deposit?

Engine carbon cleaning includes: 1, throttle cleaning and carbon cleaning, mainly depending on engine structure. From the use environment, ordinary vehicles don't need to clean the throttle and carbon deposits frequently, and direct injection engines are more likely to produce carbon deposits. This doesn't mean that the throttle and carbon deposits should be cleaned every maintenance. For carbon deposits cleaning, the intake branch pipe and the spark plug should be removed, and a high-pressure gas pipe should be connected to the spark plug to form positive pressure in the combustion chamber. 2. Clean up the carbon deposits on the branch pipes and pipelines of the intake and exhaust valve seats. This is a professional job. It requires the repair shop to turn the crankshaft with a wrench, close the intake and exhaust valves, slowly remove the carbon deposits with a shovel, and then blow out the scraped carbon deposits with high-pressure air; 3, you also need to use carburetor cleaning agent, carbon deposits in automobile engines do not need to be cleaned frequently, and important things need to be said three times, usually once every 60,000 to 80,000 kilometers. As long as the engine burns oil, it will form carbon deposits, but don't over-maintain it. In addition, you can also use a bottle to clean the carbon deposit in the nozzle and cylinder. The bottle can't clean the carbon deposit on the intake manifold and valve, so it needs to be removed and cleaned.
