This project doesn't need to be done every time.

Throttle is like a person's throat. Above is the air filter element of the engine and below is the cylinder block of the engine. I looked up the encyclopedia about the throttle, and the result is this: whether the car accelerates flexibly has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic.

Then every time I go to the 4S shop, I recommend cleaning the throttle. As mentioned earlier, cleaning the throttle can reduce fuel consumption and the engine is flexible and powerful. So should we listen to the advice of 4S shop to clean the throttle?

In theory, carbon deposition will not occur on the throttle valve without gasoline, but it does occur, mainly because the air filter element cannot filter air 100%, and impurities in the air will form carbon deposition, and some engine oil or gasoline vapor will stick to the throttle valve when entering the intake system through the crankshaft ventilation box.

It's just like a range hood at home. Pumping the air with oil fume so loudly every day will get dirty after a long time, and even affect the effect of pumping oil fume. The accelerator of a car will get dirty if it is used for a long time, which will affect the work efficiency. The main performance is that there are some unique symptoms when idling.

The common symptoms of throttle carbon deposit are increased fuel consumption, unstable idle speed and engine jitter. The main symptom I encountered was the idling jitter when waiting for the traffic lights, and then the fuel consumption was relatively high during that time.

This throttle is not designed casually. The designer fully considered the problem of dirty throttle when leaving the factory, so he designed the air filter. Just as our designers must have fully considered the needs of playing games before leaving the factory and optimized them in advance, the dirty throttle is not so easy. Many 4S shops began to recommend novice friends to clean the throttle at a distance of more than 65,438+00,000 kilometers. In fact, it is really unnecessary, mostly to make money.

Washing this thing when it is not dirty feels no different from not washing it at all. If the driving environment is good, there is no idling jitter and stable fuel consumption. 50,000 kilometers of cleaning is also possible, and there is no specific deadline.

As long as the car doesn't have the peculiar symptoms of dirty accelerator, it doesn't need to be cleaned frequently to waste money.
