Do naturally aspirated cars need to remove carbon deposits?

Naturally aspirated cars need to remove carbon deposits. There will be a lot of carbon deposits after a car travels 80 thousand kilometers, but it is not excluded that some engines with poor combustion performance will have carbon deposits around 50 thousand kilometers. It is generally recommended to clean the throttle once a year or 20,000 kilometers. Different models will have different cleaning cycles, which can be done according to the maintenance manual. The specific methods of cleaning carbon deposits in naturally aspirated vehicles are as follows: cleaning the throttle: remove the throttle, clean the front and rear of the throttle with carburetor, and dry it with cotton cloth. Clean up the carbon deposit inside the engine: pretreat it with new oil. Open the oil cover, add the cleaning agent, mix it with the old oil, and run at idle speed for about 10 minutes. Cleaning the air intake system: use the cleaning agent of the air intake system, pour it into the liquid storage tank of special cleaning equipment, connect the air intake system, and suck the cleaning agent into the air intake passage with [/k0/] to achieve the purpose of cleaning. Cleaning the carbon deposit in the intake system mainly refers to cleaning the carbon deposit in the intake and intake manifold. Its purpose is to remove carbon deposits in the intake system, increase intake flow and speed, and reduce engine jitter and idle instability.
