How is the throttle quality in Yu Hui?

The throttle valve is the throat of the automobile engine, which controls the air intake of the automobile engine, and then the driving computer judges the fuel injection quantity according to the value of the air flow sensor. Therefore, the accuracy of throttle intake is related to the fuel injection quantity. It is the premise of stable operation of automobile engine. So the accelerator pedal we step on actually controls not the accelerator, but the opening of the accelerator. ? It is recommended to clean the throttle, generally every 20 thousand kilometers or so.

The air in the engine needs to pass through our throttle, which is very easy to accumulate dust. When there is too much dust, the air entering our throttle will be blocked by dust at the same opening, resulting in less air actually entering the engine at the same opening.

Too dirty throttle will lead to power loss, unstable idle speed, and serious engine failure lights. Therefore, it is necessary for us to clean the throttle regularly to ensure that our throttle can accurately measure the amount of air entering the engine.

The vicious circle of carbon deposition, and the generation of these scales depends on the quality of air filter, engine oil, driving conditions, air temperature, engine working temperature, driving habits and many other aspects.

In other words: oil deterioration, long-term non-replacement of air filter, poor quality of air filter, etc. , will aggravate the dirty degree of the throttle.

If the idle speed of the self-priming EFI car is unstable, the car will always turn off. When cleaning the throttle, it is important to clean the idle valve. Relatively speaking, the working principle of idle valve is much more accurate than that of throttle valve.

Because gasoline can't clean the accelerator, the direct injection engine may have more carbon deposits, but it won't affect the performance of the vehicle, and generally it doesn't need to be cleaned all the time. If you are unable to accelerate or breathe at a low speed, it is time to clean the throttle.

There is no specific mileage for throttle cleaning, which mainly depends on road conditions and daily maintenance of vehicles. Self-priming engines generally use fuel additives to delay the carbon deposition in the throttle, and there will be no problem for several years and tens of thousands of kilometers.

Stop the seventh grade at the station first. So if the throttle is dirty, what impact will it have on the driving experience? Simply put, the power will drop and the fuel consumption will remain unchanged; The power has not changed, but the fuel consumption has increased. ...

Open the cover and prepare to clean the throttle. When the driving experience has not changed, the air environment is good and the road conditions are not particularly congested, go to the store for inspection every 20,000 kilometers, and judge whether to clean according to the test results. ...

When the engine trim cover is removed, the position of the throttle valve can be clearly seen. ...

Remove the throttle. The maintenance master said that under normal circumstances, cleaning once every 20,000 kilometers is enough. If you take turns to do major maintenance and minor maintenance every other year, do it together with major maintenance. When replacing the air filter, it can be done conveniently together.

Fortunately, there is not so much black carbon deposition on the removed throttle. Never don't clean the throttle! Don't clean the throttle frequently!

The position and removal of the throttle, the removal and cleaning of the throttle, its principle is very easy to understand, that is, the whole throttle is removed and then cleaned.

Use throttle cleaner to clean the dirt inside the throttle and the valve, and wipe it with a clean cloth during cleaning. ...

After cleaning, put it back in place, but the biggest difficulty for ordinary users is how to remove the throttle. When you open the engine room, different models have different throttle positions. ...

After cleaning, check tire pressure. In winter, the weather is cold, and the tires expand when heated and contract when cooled. Be sure to check the tire pressure regularly. ...

After cleaning, I drove the seventh car out of the maintenance workshop. The throttle position of each model is different, so disassembly is a bit troublesome. I have to go to the 4S shop to clean it, because I have no tools [hee hee].

After cleaning the throttle, it's time to go home. When driving, you must obey the traffic rules, stop at the red light, drive safely and be a law-abiding citizen. ...

To sum up, if riders with tools can clean themselves, friends with strong hands-on ability can try. Of course, removing the throttle mainly depends on proficiency. In case the sensor is damaged during disassembly, it is still a headache. The benefits of disassembling and cleaning the throttle are also obvious: it is not difficult, everything is transparent, and it is clear at a glance whether it is cleaned or not.
