节气门前面虽然都会有空气滤清器过滤空气，但是它还是很容易就会脏掉。节气门叶片如果脏掉，会对引擎产生影响就是怠速不稳，虽然目前喷射引擎的车子都有步计马达、甚至电子节气门来控制怠速，不过定期清洁仍然有其必要性的。下面
济南奥迪汽车维修人员为您讲解。
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.
简单来说，当油门踏板踩下后，透过拉索将节气门叶片拉开，此时空气进入进气歧管，而引擎的侦测机制发现空气变多了、就增加喷油量，以便搭配出标准空燃比的燃料进入燃烧室。当然这其中还有一堆复杂的过程。
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，一般师傅使用化清剂的方式进行清洗时，会直接朝节气门内部做喷洒的清洁动作。而这次我们使用擦拭的方式来进行。这是因为化清剂会腐蚀塑胶、橡胶类的材料，而且还会将所有的润滑油通通溶解。所以喷洒的方式虽然面积可以更广泛、但日久也会造成内部机件的损伤，容易造成怠速步进马达、油封等问题。
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.
清除完毕后，将软管安装回去时也要注意，因为这次示范的是涡轮增压车型，所以万一软管没有安装牢靠，进气压力过大时是有可能发生漏气或软管脱落的现象。而在所有动作都完成后，刚开始发动的瞬间也不要猛加油拉转速，一方面是车子尚在冷车范围未达工作温度，另一方面是如果内部有没安装好的问题也能及时发现，不会引发更大的故障问题出现。
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://www.lutongqixiu.com Consult!
