節氣門前面雖然都會有空氣濾清器過濾空氣，但是它還是很容易就會臟掉。節氣門葉片如果臟掉，會對引擎產生影響就是怠速不穩，雖然目前噴射引擎的車子都有步計馬達、甚至電子節氣門來控制怠速，不過定期清潔仍然有其必要性的。下面
濟南奧迪汽車維修人員為您講解。
Although there is an air filter in front of the throttle to filter the air, it is still easy to get dirty. If the throttle blade is dirty, it will have an impact on the engine, that is, the idle speed is unstable. Although the current vehicles with injection engines have a stepper motor or even an electronic throttle to control the idle speed, regular cleaning is still necessary. Next, the Jinan Audi auto maintenance personnel will explain to you.
簡單來說，當油門踏板踩下后，透過拉索將節氣門葉片拉開，此時空氣進入進氣歧管，而引擎的偵測機制發現空氣變多了、就增加噴油量，以便搭配出標準空燃比的燃料進入燃燒室。當然這其中還有一堆復雜的過程。
To put it simply, when the accelerator pedal is depressed, the throttle blade is pulled open through the cable. At this time, the air enters the intake manifold. When the engine's detection mechanism finds that there is more air, the fuel injection volume is increased, so that the fuel with a standard air fuel ratio can enter the combustion chamber. Of course, there are a lot of complicated processes.
在早期，一般師傅使用化清劑的方式進行清洗時，會直接朝節氣門內部做噴灑的清潔動作。而這次我們使用擦拭的方式來進行。這是因為化清劑會腐蝕塑膠、橡膠類的材料，而且還會將所有的潤滑油通通溶解。所以噴灑的方式雖然面積可以更廣泛、但日久也會造成內部機件的損傷，容易造成怠速步進馬達、油封等問題。
In the early days, when cleaning with chemical detergent, the general master will directly spray the inside of the throttle valve. This time we use the method of wiping. This is because the detergent will corrode plastic and rubber materials, and will dissolve all lubricating oils. Therefore, although the spraying method can cover a wider area, it will also cause damage to internal parts over time, which is easy to cause problems such as idle stepper motor and oil seal.
清除完畢后，將軟管安裝回去時也要注意，因為這次示范的是渦輪增壓車型，所以萬一軟管沒有安裝牢靠，進氣壓力過大時是有可能發生漏氣或軟管脫落的現象。而在所有動作都完成后，剛開始發動的瞬間也不要猛加油拉轉速，一方面是車子尚在冷車范圍未達工作溫度，另一方面是如果內部有沒安裝好的問題也能及時發現，不會引發更大的故障問題出現。
After cleaning, pay attention when installing the hose back. Because this demonstration is for turbocharged vehicles, in case the hose is not firmly installed and the intake pressure is too high, air leakage or hose falling off may occur. After all the movements are completed, do not suddenly refuel the engine and rev it at the beginning of the start. On the one hand, the car is still in the cold range and does not reach the operating temperature. On the other hand, if there is a problem with the internal installation, it can also be found in a timely manner, which will not lead to more serious problems.
The above is a comprehensive question about how to maintain the throttle. No matter which part of the car needs maintenance, it is also an important way to increase the service life of the car. It is recommended that all car owners should regularly maintain their cars. Come to our website for more information http://m.liangshuijing.cn Consult!
