清洗節(jié)氣門作為一種維修手段，如今更多的出現(xiàn)在了4S店的常規(guī)保養(yǎng)項目里，那么下面濟南奧迪汽車維修人員就來講講清洗節(jié)氣門的相關(guān)事項吧。

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.

節(jié)氣門在哪兒？

Where is the throttle?

打開發(fā)動機艙，在進氣道與發(fā)動機“接壤”的地方，便是節(jié)氣門。節(jié)氣門位于空氣濾清器與進氣歧管之間，固定在進氣歧管上。通常打開發(fā)動機艙便可看到，有發(fā)動機蓋板的則需要拆下蓋板。

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.

節(jié)氣門是干嘛的？

What is the throttle valve for?

節(jié)氣門是控制發(fā)動機進氣量的閥門。

The throttle valve is the valve that controls the intake air volume of the engine.

通俗來說，節(jié)氣門即油門。當你腳踩油門的時候，實際控制的就是節(jié)氣門的開度，油門深踩，則節(jié)氣門開度變大，進氣量增大，發(fā)動機再根據(jù)進氣量的多少來匹配噴油量，從而起到“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".

節(jié)氣門為什么會變臟？

Why does the throttle get dirty?

車輛長時間使用后，節(jié)氣門會變臟其實是很正常的事情。原因有兩個，一是進氣中可能含有的水分和微粒（空氣濾清器不可能全部過濾），二是從曲軸箱引來的“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.

節(jié)氣門變臟了會怎樣？

What happens when the throttle gets dirty?

節(jié)氣門變臟，直接影響到的就是發(fā)動機怠速和加速性能，表現(xiàn)為發(fā)動機怠速抖動，車輛加速不暢，踩油門后發(fā)動機反饋不靈敏，油耗增加，怠速突然熄火等，對發(fā)動機性能還是會造成很大影響的。

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.

節(jié)氣門多長時間清洗一次？

How often is the throttle cleaned?

從節(jié)氣門變臟的原因來看，就能看出節(jié)氣門臟與否其實與公里數(shù)、時間等是沒有太大關(guān)系的，所以節(jié)氣門什么時候應(yīng)該清洗，不能以公里數(shù)或時間來作為限定條件，如果當?shù)乜諝赓|(zhì)量好，節(jié)氣門清洗周期就長，大概是這么個道理。不過一般以兩萬公里為參考。

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.

如何判斷節(jié)氣門需要清洗？

How to judge whether the throttle valve needs cleaning?

不是用車時間，不是行駛公里數(shù)，而是另外一個參數(shù)：節(jié)氣門開度。每一輛車都有一個節(jié)氣門開度閾值（有的車型會在用戶手冊上標明，有的則沒有，閾值設(shè)定也都有所差別），在這個閾值之內(nèi)即正常，大于這一閾值則需要清洗。

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.

節(jié)氣門開度需要通過電腦檢測儀檢測，不過很少有人檢測，所以，在每次清洗節(jié)氣門之間，先向技師要一下這個數(shù)據(jù)，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.

清洗節(jié)氣門其實并不難，如果有一定動手能力，那可以自己操作，操作案例網(wǎng)上大把，工具準備也很簡單，不過如果動手能力比較弱，建議還是找一個正規(guī)的維修廠家進行比較好。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.nikond90.cn咨詢吧！

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.nikond90.cn Consult!
