清洗节气门作为一种维修手段，如今更多的出现在了4S店的常规保养项目里，那么下面
济南奥迪汽车维修人员就来讲讲清洗节气门的相关事项吧。
As a maintenance method, cleaning the throttle valve is now more common in the routine maintenance items of 4S stores. Now, the maintenance personnel of Jinan Audi Automobile will talk about cleaning the throttle valve.
节气门在哪儿？
Where is the throttle?
打开发动机舱，在进气道与发动机“接壤”的地方，便是节气门。节气门位于空气滤清器与进气歧管之间，固定在进气歧管上。通常打开发动机舱便可看到，有发动机盖板的则需要拆下盖板。
Open the engine compartment, and the throttle valve is located at the place where the air inlet is "adjacent" to the engine. The throttle valve is located between the air filter and the intake manifold and is fixed on the intake manifold. Generally, it can be seen by opening the engine compartment. If there is an engine cover plate, it needs to be removed.
节气门是干嘛的？
What is the throttle valve for?
节气门是控制发动机进气量的阀门。
The throttle valve is the valve that controls the intake air volume of the engine.
通俗来说，节气门即油门。当你脚踩油门的时候，实际控制的就是节气门的开度，油门深踩，则节气门开度变大，进气量增大，发动机再根据进气量的多少来匹配喷油量，从而起到“加油”的作用。
Generally speaking, the throttle is the accelerator. When you step on the accelerator, what you actually control is the throttle opening. If you step on the accelerator deeply, the throttle opening will become larger and the intake volume will increase. The engine will match the fuel injection volume according to the intake volume, thus playing the role of "refueling".
节气门为什么会变脏？
Why does the throttle get dirty?
车辆长时间使用后，节气门会变脏其实是很正常的事情。原因有两个，一是进气中可能含有的水分和微粒（空气滤清器不可能全部过滤），二是从曲轴箱引来的“含油蒸汽”。
It is normal that the throttle valve will get dirty after the vehicle is used for a long time. There are two reasons. One is the water and particles that may be contained in the intake air (the air filter cannot filter all of them), and the other is the "oily steam" from the crankcase.
节气门变脏了会怎样？
What happens when the throttle gets dirty?
节气门变脏，直接影响到的就是发动机怠速和加速性能，表现为发动机怠速抖动，车辆加速不畅，踩油门后发动机反馈不灵敏，油耗增加，怠速突然熄火等，对发动机性能还是会造成很大影响的。
Dirty throttle directly affects the engine's idle speed and acceleration performance, which is manifested by engine idling jitter, poor vehicle acceleration, insensitive engine feedback after stepping on the accelerator, increased fuel consumption, sudden idling, etc., which will still have a great impact on the engine's performance.
节气门多长时间清洗一次？
How often is the throttle cleaned?
从节气门变脏的原因来看，就能看出节气门脏与否其实与数、时间等是没有太大关系的，所以节气门什么时候应该清洗，不能以数或时间来作为限定条件，如果当地空气质量好，节气门清洗周期就长，大概是这么个道理。不过一般以两万为参考。
From the cause of the dirty throttle, it can be seen that whether the throttle is dirty or not has little to do with the mileage and time. Therefore, when the throttle should be cleaned should not be limited by the mileage or time. If the local air quality is good, the cleaning cycle of the throttle will be long. However, the reference is generally 20,000 km.
如何判断节气门需要清洗？
How to judge whether the throttle valve needs cleaning?
不是用车时间，不是行驶数，而是另外一个参数：节气门开度。每一辆车都有一个节气门开度阈值（有的车型会在用户手册上标明，有的则没有，阈值设定也都有所差别），在这个阈值之内即正常，大于这一阈值则需要清洗。
It is not the driving time or mileage, but another parameter: throttle opening. Each vehicle has a throttle opening threshold (some models will be marked in the user manual, some models will not, and the threshold setting will be different). If it is within this threshold, it is normal. If it is greater than this threshold, it needs to be cleaned.
节气门开度需要通过电脑检测仪检测，不过很少有人检测，所以，在每次清洗节气门之间，先向技师要一下这个数据，避免被坑。
The throttle opening needs to be detected by a computer detector, but few people detect it. Therefore, before cleaning the throttle, ask the technician for this data to avoid being trapped.
It's not difficult to clean the throttle valve. If you have some hands-on skills, you can do it yourself. There are a lot of operation cases online, and the tool preparation is also very simple. However, if you have weak hands-on skills, it is recommended to find a regular maintenance manufacturer. More relevant content will come to our website http://www.lutongqixiu.com Consult!
