Hundreds of thousands of kilometers have not cleaned up carbon deposits.

If the throttle valve is not cleaned for 65,438 438+ 10/00000 km, the carbon deposit will be very serious, which will cause blockage, affect the air intake of the engine, lead to the car idling jitter, flameout, unsmooth acceleration and a sense of frustration.

It is recommended to clean the throttle every 20,000 kilometers. If the driving environment is good and there is no idling jitter, it can be cleaned every 50,000 kilometers. There are two ways to clean the throttle, one is to remove it for cleaning, and the other is not to remove it. If the throttle is not very dirty, it can be cleaned directly with cleaning agent without disassembly. If it is dirty, it needs to be taken apart and cleaned. Although it is more troublesome, the effect is better.

Methods of removing carbon deposits from automobiles:

1. Clean the carbon deposit on the throttle: remove the engine decorative cover, remove the throttle, clean it with carburetor cleaner, dry it with cotton cloth and install it;

2. Clean the carbon deposit inside the engine: open the engine oil cover, pour the whole tank of cleaning agent, mix it with the old engine oil, cover the engine oil cover, and shut down the engine after idling for 10 minutes;

3. Clean up the carbon deposit in the oil circuit: Before refueling, add the whole bottle of fuel additive to the fuel tank. Cleaning the carbon deposit in the oil circuit includes cleaning the oil nozzle, combustion chamber, spark plug, throttle and other parts;

4. Cleaning the carbon deposit in the air intake system: buy a bottle of cleaning agent for 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 by vacuum to achieve the cleaning purpose.
