Why should the throttle be cleaned regularly? Why does the throttle get dirty and black?

When we go for maintenance, car maintenance technicians often say that the "throttle valve" needs maintenance. Does the throttle really need cleaning? Bian Xiao let everyone know the throttle. Throttle is actually a valve of a car, which plays a role in controlling the air intake of the engine. To put it simply, the deeper you step on the accelerator, the more air intake, the more complete oil and gas combustion and the faster the vehicle speed. Therefore, the throttle directly affects the power and performance of the car, which can be said to be a very important part of the car. Why does the throttle get dirty and black? First, let's see why this throttle valve is dirty and black. The air filter can't filter all the dirt, throttle. It is a valve that connects the air filter and the intake pipe of the engine and controls the intake of the engine. This air filter is filtering, but nothing can pass through it. Sure enough, dust and dirt contact the air through the throttle surface. The oil vapor generated by the engine oil condenses and adheres, and the working temperature of the engine is relatively high, so that the engine oil generates oil vapor. When the engine is idling or running at a low speed, the oil and gas will carry these colloids in the fuel and condense or transport them to the throttle at a lower temperature. The dust in the mixed air burned black, and together with the dust in the air, all kinds of steamed things were as black as coke. In short, when we cook, the truth of this lampblack is the same. It's a day or two after you clean it, and after a week or two, it slowly begins to turn black. You also don't be too incredible. If there is a lot of pollution, the throttle valve that affects the engine action is polluted and may be slightly blocked. Therefore, the air intake control may be incorrect, thus affecting the action of the engine. Idle speed is unstable, acceleration and power are worse, and fuel consumption is higher. That's because there is less inhalation. How often should the throttle be washed? Generally, it is washed once every 20,000 kilograms. From the perspective of rhythm or frequency, it is generally washed once every 20,000 kilograms. Pollution and blockage can be cleaned up in advance. If the air pollution is serious, or friends in the north, it is possible to go to pm2.5 and all kinds of coal ash in winter, and wash this 10000 kg to 15000 kg once. In other words, our friends in the eastern coast or Guangzhou are very congested and often walk or park, so they may wash every 10 thousand kilometers. Look here, I think you have understood the necessity of cleaning the throttle. So, when the garage recommends it to you, you don't have to refuse.
