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(xiàng)目里，那么下面濟(jì)南奧迪汽車維修人員就來(lái)講講清洗節(jié)氣門的相關(guān)事項(xiàng)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(kāi)發(fā)動(dòng)機(jī)艙，在進(jìn)氣道與發(fā)動(dòng)機(jī)“接壤”的地方，便是節(jié)氣門。節(jié)氣門位于空氣濾清器與進(jìn)氣歧管之間，固定在進(jìn)氣歧管上。通常打開(kāi)發(fā)動(dòng)機(jī)艙便可看到，有發(fā)動(dòng)機(jī)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(dòng)機(jī)進(jìn)氣量的閥門。

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

通俗來(lái)說(shuō)，節(jié)氣門即油門。當(dāng)你腳踩油門的時(shí)候，實(shí)際控制的就是節(jié)氣門的開(kāi)度，油門深踩，則節(jié)氣門開(kāi)度變大，進(jìn)氣量增大，發(fā)動(dòng)機(jī)再根據(jù)進(jìn)氣量的多少來(lái)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(huì)變臟？

Why does the throttle get dirty?

車輛長(zhǎng)時(shí)間使用后，節(jié)氣門會(huì)變臟其實(shí)是很正常的事情。原因有兩個(gè)，一是進(jìn)氣中可能含有的水分和微粒（空氣濾清器不可能全部過(guò)濾），二是從曲軸箱引來(lái)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(huì)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(dòng)機(jī)怠速和加速性能，表現(xiàn)為發(fā)動(dòng)機(jī)怠速抖動(dòng)，車輛加速不暢，踩油門后發(fā)動(dòng)機(jī)反饋不靈敏，油耗增加，怠速突然熄火等，對(duì)發(fā)動(dòng)機(jī)性能還是會(huì)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(zhǎng)時(shí)間清洗一次？

How often is the throttle cleaned?

從節(jié)氣門變臟的原因來(lái)看，就能看出節(jié)氣門臟與否其實(shí)與公里數(shù)、時(shí)間等是沒(méi)有太大關(guān)系的，所以節(jié)氣門什么時(shí)候應(yīng)該清洗，不能以公里數(shù)或時(shí)間來(lái)作為限定條件，如果當(dāng)?shù)乜諝赓|(zhì)量好，節(jié)氣門清洗周期就長(zhǎng)，大概是這么個(gè)道理。不過(guò)一般以兩萬(wàn)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(shí)間，不是行駛公里數(shù)，而是另外一個(gè)參數(shù)：節(jié)氣門開(kāi)度。每一輛車都有一個(gè)節(jié)氣門開(kāi)度閾值（有的車型會(huì)在用戶手冊(cè)上標(biāo)明，有的則沒(méi)有，閾值設(shè)定也都有所差別），在這個(gè)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(kāi)度需要通過(guò)電腦檢測(cè)儀檢測(cè)，不過(guò)很少有人檢測(cè)，所以，在每次清洗節(jié)氣門之間，先向技師要一下這個(gè)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(shí)并不難，如果有一定動(dòng)手能力，那可以自己操作，操作案例網(wǎng)上大把，工具準(zhǔn)備也很簡(jiǎn)單，不過(guò)如果動(dòng)手能力比較弱，建議還是找一個(gè)正規(guī)的維修廠家進(jìn)行比較好。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.gxnn10z.com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.gxnn10z.com Consult!
