Car carbon deposition has always been the most headache of car maintenance, but if we pay attention to good driving habits in the daily driving process, it can greatly reduce the formation of car carbon deposition. Here are some basic techniques.

1、不要長(zhǎng)時(shí)間怠速行駛

1. Don't idle for a long time.

怠速時(shí)間長(zhǎng)，發(fā)動(dòng)機(jī)達(dá)到正常溫度所需的時(shí)間也就變長(zhǎng)，汽油被噴到氣門(mén)背面后蒸發(fā)的速度就慢，積碳也由此而生。同時(shí)經(jīng)常怠速行駛，進(jìn)入發(fā)動(dòng)機(jī)的空氣流量也就小，這樣對(duì)積碳的沖刷作用變得也很弱，會(huì)促進(jìn)積碳的沉積。

If the idle time is long, the time required for the engine to reach normal temperature will be longer, and gasoline will evaporate slowly when it is injected into the back of the valve, resulting in carbon deposition. At the same time, often idling, the air flow into the engine will be small, so that the erosion of carbon deposits becomes very weak, will promote the deposition of carbon deposits.

2、注意熄火時(shí)機(jī)

2. Pay attention to the timing of extinguishing

對(duì)于裝有渦輪增壓器的汽車(chē)，在高速行駛或是爬坡后不要馬上熄火，在怠速運(yùn)轉(zhuǎn)10分鐘后再熄火，裝有渦輪增壓器的汽車(chē)其形成積碳的速度比一般自然吸氣式的汽車(chē)要快數(shù)倍。

For automobiles equipped with turbochargers, do not extinguish immediately after high-speed driving or climbing, and then extinguish after idling for 10 minutes. Cars equipped with turbochargers can accumulate carbon several times faster than those equipped with natural aspiration.

建議有車(chē)族在常規(guī)保養(yǎng)都滿(mǎn)足的條件下每2萬(wàn)至4萬(wàn)公里時(shí)做一下進(jìn)氣系統(tǒng)的免拆清洗，也就是在發(fā)動(dòng)機(jī)不解體的前提下用專(zhuān)用設(shè)備專(zhuān)用方法對(duì)車(chē)輛的進(jìn)氣道、氣門(mén)、油路等容易形成積碳的部位進(jìn)行清積碳的操作。

It is suggested that the car owners should clean the intake system without disassembly every 20,000 to 40,000 kilometers under the conditions of routine maintenance. That is to say, under the premise that the engine does not disintegrate, the special equipment method should be used to clean the intake port, valve, oil path and other parts of the vehicle which are easy to form carbon deposit.

3、使用清潔汽油

3. Use clean gasoline

汽油中的雜質(zhì)是形成積碳的主要成分，所以清潔度高的汽油形成積碳的趨勢(shì)就弱一些。但是要注意高標(biāo)號(hào)并不等于高質(zhì)量，標(biāo)號(hào)只代表油的辛烷值，并不能代表品質(zhì)和清潔程度。一些車(chē)主為了保證汽油的清潔度，會(huì)采用在汽油里添加汽油清潔劑的做法。這樣可有效地防止在金屬表面形成積碳結(jié)層，并能逐漸活化原有的積碳顆粒并慢慢去除，從而保護(hù)發(fā)動(dòng)機(jī)免受傷害。不過(guò)汽油清潔劑的添加一定要慎重，如果加入了偽劣的產(chǎn)品會(huì)得到相反的效果。

Impurities in gasoline are the main component of carbon deposition, so the trend of carbon deposition in gasoline with high cleanliness is weaker. However, it should be noted that high labeling does not mean high quality. The labeling only represents the octane number of the oil, but does not represent the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will add gasoline detergent to gasoline. This can effectively prevent the formation of carbon deposits on the metal surface, and gradually activate the original carbon deposits and slowly remove them, thus protecting the engine from damage. However, the addition of gasoline detergent must be careful, if the addition of fake and inferior products will have the opposite effect.
