What should I do if the throttle is dirty?

Now many car owners like to maintain their own vehicles, so let's share the car throttle that many car owners are confused about today. What is the performance of dirty throttle? How often is the throttle cleaned?

What is a throttle valve?

Throttle is a controllable valve, which controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. We can describe the throttle valve as an engine. The depth of stepping on the accelerator determines the power and cooperation of the engine through the opening of the accelerator.

How does a dirty throttle behave? The most obvious nature is the power of the engine. When the idle speed of the vehicle is unstable, it is difficult to start and the power drops, it means that the throttle of the vehicle may need to be cleaned.

How often is the throttle cleaned?

Generally speaking, 4s shops will advise car owners to clean the throttle regularly, usually once every 20,000-40,000 kilometers. However, it should be noted that it is not good to check and clean the throttle. Excessive cleaning will lead to premature scrapping of the throttle. Repeated and frequent cleaning will cause the special coating in the throttle valve cavity to be washed away gradually, and the inner cavity will lose its coating, which will easily lead to the adhesion of engine oil, thus forming a vicious circle, and the final result is scrapping.

But remind the owner that there is no need to clean the accelerator of the car often. You can judge from the feedback of the car power. If the idle speed is unstable, it is difficult to start and the power drops, clean the throttle again. If cleaning the car throttle still doesn't solve the problem, then the problem is likely to come from other parts.

There are two ways to clean the throttle valve, namely disassembly cleaning and disassembly-free cleaning. Generally, the throttle of 4s shops is disassembled and cleaned, and the whole throttle is always disassembled, and then a special cleaning agent is used for comprehensive cleaning and maintenance. Although this method is troublesome, it is better than thorough cleaning, and the price is high. Generally, the price of a 4s shop is around 300-500 yuan.

Disassembly-free cleaning is to spray the accelerator cleaning agent directly on the rag to scrub the accelerator. The whole process does not need to disassemble the throttle assembly, and the operation is relatively simple and convenient. Car owners can buy their own cleaning agents and then clean the throttle. However, although this method is simple, the cleaning effect is average, and it is best to use it on the throttle that is not particularly dirty.

Precautions for Throttle: After cleaning the throttle, the throttle opening must be reset, otherwise the car computer has already remembered the opening when there is carbon deposit. If it is not reset, the engine will have unstable idle speed and overspeed, even more serious than before cleaning. Different vehicle reset methods are different, so I won't introduce them here. If the owner has concerns, it is best to go to a professional repair shop or 4s shop for repair.
