4S repair shop cleaning automobile accelerator

I believe that every time you go to the 4S shop to maintain your car, a master will advise you to clean the throttle of your car and tell you what consequences and hidden dangers will be caused if you don't clean the throttle. In fact, you may not fully understand, thinking that "you are the master, you are right". Is it useful to clean the throttle? Is this money worth spending? How often do you clean it? What exactly is a throttle valve?

Is it necessary to clean the throttle regularly?

First of all, it is meaningful to clean the throttle regularly. During the long-term use of the engine, carbon deposits will inevitably accumulate around the throttle. Unclean throttle will affect ECU's control of throttle opening, thus affecting idle speed and causing jitter and other problems. More seriously, if a carbon step is formed, the throttle will get stuck, which may lead to further failure and flameout.

If there is less dirt on the throttle, the driving computer of the engine can adjust the air intake by itself. In fact, there is no need to clean it at this time, and it is ineffective and a waste of money.

However, the dirty throttle may be blocked a little, resulting in inaccurate intake control, unstable idle speed, poor acceleration and power, and high fuel consumption. That's because there is less air intake, so it is necessary for us to wash it at this time. Of course, some friends will know this very well and can clean it themselves, but friends who don't know it are better to find professional institutions and people.

How often should the throttle be cleaned? Why is it dirty?

Generally speaking, if you go to maintain your car every time, someone will ask you if you want to spend hundreds of dollars to clean the accelerator, which is not reliable. It's not too late to think about this problem until our car travels about 20 thousand kilometers.

How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and many other aspects. Dirty oil and air filter have not been replaced for a long time, and the quality of air filter is poor. , will aggravate the dirty degree of the throttle.

What is a throttle valve?

Throttle is a controllable valve, which is used to control air to enter the engine. Above (or in front of) is the air filter, and below is the engine block. The position of the throttle valve is equivalent to the "throat" of the car. After the air enters the intake pipe, it needs to pass through the throttle valve, and then it is mixed with gasoline to form a combustible mixture to participate in combustion and work. Electronic throttle system is widely used in modern cars.

In layman's terms, this air filter is like a mask, which is responsible for filtering gas. The throttle valve is like a nose, which can control the amount of gas entering by closing and opening the air. For example, sometimes exercise needs a lot of breath, and sometimes it doesn't.

Throttles are like our mouths or noses. It controls the amount of air entering the body by opening and contracting. It is good to wash it regularly, usually once every 20 thousand kilometers. If the pollution is serious, it can be cleaned in advance.
