This car has been used for half a year. How often can the throttle be cleaned?

The accelerator is a car part that our car owners often hear about. This throttle valve is located between the air filter and the intake manifold, and it is a controllable valve to control air to enter the engine, so it is called the throat of the automobile engine. When stepping on the accelerator at ordinary times, ECU controls the air intake by controlling the size of the accelerator, and the inhaled gas enters the engine for combustion and work after mixing with gasoline. The amount of work done by the engine depends on the depth of the throttle. The deeper you step on it, the greater the throttle opening, the more air intake of the engine, the more complete the oil-gas combustion and the stronger the power.

So, why clean the throttle? Because the throttle will be "dirty", affected by the EFI engine, the cylinder will inject oil first and then ignite every time it works. When the engine is turned off, the instantaneous ignition of the engine will be cut off immediately. However, the gasoline sprayed by this working cycle cannot be recovered and can only be attached to the throttle and the wall of the combustion chamber. Gasoline is easy to volatilize, but paraffin and gum in gasoline will stay. In the long run, these waxes and colloids will accumulate thicker and thicker, plus repeated heating.

So, how do you know that the throttle has become "dirty"? Because the throttle controls the accuracy and smoothness of the engine intake, once the throttle is "dirty". It will lead to insufficient air intake of the engine, inaccurate air intake control, unstable idle speed, jitter, weak acceleration and increased fuel consumption. This is similar to our people's cold and stuffy nose. If these problems occur, it is generally necessary to clean the throttle.

So, how often should the throttle be cleaned? Under normal circumstances, it is recommended that car owners clean the throttle every 20-40 thousand kilometers, but this is just a reference value for everyone. The specific cleaning cycle depends on personal car habits and the environment inside the car. For example, most of you drive on dusty roads, so the throttle will definitely be dirty, and it may be cleaned less than 20,000 kilometers.

Therefore, the owner can judge according to some phenomena of driving at ordinary times. If the car has unstable idling or weak acceleration, then you should think about whether the throttle has not been cleaned for a long time, because this situation is mostly caused by dirty throttle. In this case, it is recommended to go back to the store for inspection as soon as possible to determine the actual situation of the throttle and clean it well.
