Idle jitter is related to it! This delicate part should also be well maintained.

As the heart of a car, the importance of daily engine maintenance is self-evident, and everyone knows it. And every part of the engine has its own maintenance cycle. What I want to talk to you today is a more subtle component-the throttle. Does this delicate part really need to be cleaned regularly? How often should it be cleaned? We continue to look down.

Who is the throttle?

Before talking about maintenance, let's take a brief look at this "delicate" part. As the name implies, the throttle is to control the amount of air entering the engine. It can be regarded as a door of the engine, one side is connected with the air filter, and the other side is the engine block. Its duty is to control the air intake of the engine, and the degree of opening and closing is directly related to the depth of our stepping on the accelerator. When the throttle is shallow, the opening and closing degree will be small, and the air intake will be less; The deeper you step on the accelerator, the greater the opening and closing degree and the more air intake.

Do you need regular cleaning?

The answer is yes. As mentioned earlier, the throttle valve is a door of the engine, and both ends are connected with the engine and the air filter. However, even if the air filter is checked first, every time the engine inhales air, all kinds of dust particles in the air will be attached to the throttle more or less, and the steam generated after engine oil combustion will also be distributed to the throttle, which will cause what we often call carbon deposition for a long time.

If the accelerator is too dirty, it will affect the use of the vehicle. The first problem is vehicle jitter, that is, unstable idle speed. If the throttle valve is not cleaned for a long time, serious carbon deposition will affect the opening and closing of the throttle valve, which will further affect the intake of the engine, and the engine will shake and the idle speed will be unstable. Secondly, if carbon deposition is serious, it will also lead to an increase in fuel consumption.

How often do you clean it?

Under normal circumstances, according to the suggestion of 4S shop, it is generally cleaned every 20,000 kilometers. But it still depends on the specific car use. If there is more dusty weather, you should pay more attention. In addition, if you have strong hands-on ability, you can also clean it yourself. Buy detergent and spray it directly on the accelerator to scrub. This method is convenient and concise, but the cleaning effect is relatively general. If the cleaning is thorough enough, it needs to be removed, which requires a certain technical content.
