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

　　1. 不要長時間無所事事

　　1. Don't sit idle for a long time.

　　當汽油被噴到閥門的背面時，碳就會積聚起來，并且蒸發得更慢。同時，經常怠速行駛時，進入發動機的空氣流量很小，因此對積炭的侵蝕變得非常微弱，會促進積炭。

　　When gasoline is injected into the back of the valve, the carbon accumulates and evaporates more slowly. At the same time, when driving at idle speed, the air flow into the engine is very small, so the erosion of carbon deposit becomes very weak, which will promote carbon deposit.

　　注意火災發生的時間

　　Pay attention to the time of fire

　　裝有渦輪增壓器的汽車，高速行駛或爬坡后，切勿立即失速，怠速10分鐘后再失速。配備渦輪增壓器的汽車形成碳沉積的速度比配備自然靈感的汽車快幾倍。

　　Vehicles equipped with turbochargers should not stall immediately after high-speed driving or climbing, and stall again after idling for 10 minutes. Vehicles equipped with turbochargers deposit carbon several times faster than vehicles equipped with natural inspiration.

　　建議在滿足所有日常維護要求的情況下，每2 ~ 4萬公里不拆、不清洗進氣系統。換句話說，在發動機不解體的前提下，應采用專用設備和專用方法對進氣道、閥門、油路等容易形成積碳的車輛部件進行清碳。

　　It is suggested that the intake system should not be dismantled or unclearly washed every 20 to 40,000 kilometers under the condition of meeting all daily maintenance requirements. In other words, on the premise that the engine does not disintegrate, special equipment and special methods should be adopted to remove carbon from vehicle parts which are easy to form carbon deposit, such as intake, valve, oil path, etc.

　　使用清潔汽油

　　Use clean gasoline

　　汽油中的雜質是形成碳沉積的主要成分，因此高清潔度汽油形成碳沉積的趨勢較弱。然而，應該注意的是，高標簽并不等于高質量。標簽只代表油的辛烷值，而不是質量和清潔度。為了保證汽油的清潔，一些車主會在汽油中添加汽油清潔劑。這樣可以有效的防止金屬表面積碳層的形成，并能逐漸激活原有的積碳顆粒，慢慢的去除，從而保護發動機不受損壞。但是，汽油洗滌劑的添加一定要小心，如果添加假冒產品會得到相反的效果。

　　Impurities in gasoline are the main components of carbon deposition, so the trend of carbon deposition in high cleanliness gasoline is weak. However, it should be noted that high label is not equal to high quality. The label only represents the octane number of the oil, not its 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 deposit on metal surface, and gradually activate the original carbon deposit particles, slowly remove, thus protecting the engine from damage. However, the addition of gasoline detergent must be careful, if the addition of counterfeit products will have the opposite effect.
