How often is the throttle valve cleaned?

The throttle cleaning of Pacific Auto Network is generally carried out once every 20,000-40,000 kilometers, and the frequency of cleaning the throttle should not be too frequent. Otherwise, excessive cleaning will lead to the gradual cleaning of the special coating of the throttle cavity, and the cavity will lose its coating, which is more likely to cause greasy adhesion.

It is recommended to clean the throttle every 20,000-40,000 kilometers, and the frequency of cleaning the throttle should not be too frequent, otherwise excessive cleaning will lead to the gradual cleaning of the special coating of the throttle cavity, and the inner cavity will lose its coating, which is more likely to lead to greasy adhesion.

Some car owners said they regretted cleaning the throttle. Originally, the throttle should be cleaned regularly, but the throttle opening did not reset after cleaning, resulting in unstable idle speed and high engine speed. This situation can make the vehicle disappear after driving for a period of time.

In fact, throttle cleaning is not a maintenance project, it is closer to a maintenance project. If there is nothing wrong with the car, the owner does not need to deliberately clean the throttle. The owner can judge according to the power feedback and driving state of the vehicle. If there are symptoms such as unstable idle speed, difficulty in starting, power drop, etc., the fault can be eliminated by cleaning the throttle again.

Throttle is a controllable valve that controls air to enter the engine. We can vividly describe the throttle as the "throat" of the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. The depth of stepping on the accelerator determines the size and fit of engine power through the opening of the accelerator.

There are two ways to clean the throttle valve, namely, disassembly-free cleaning and disassembly-cleaning, each with its own advantages and disadvantages. The biggest feature of disassembly-free cleaning is its simplicity and convenience. Spray the throttle cleaner directly on the wiping cloth or directly on the throttle, and then scrub the throttle. The disadvantage is that the cleaning effect is average, which is suitable for throttle valves that are not particularly dirty.

Dismantling and washing is very troublesome. It is necessary to remove the whole throttle assembly, and then clean it thoroughly with special cleaning agent before recovery. Although the steps are cumbersome, the advantage is that the cleaning effect is thorough, but the price is relatively expensive.

Thirdly, some cars need to reset the throttle opening after cleaning the throttle, otherwise the car computer has memorized the opening when there is carbon deposit. If it is not reset, the idle speed of the engine is unstable and the speed is high, and the result is not worth the loss.
