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. 不要长时间无所事事

　　1. Don't sit idle for a long time.

　　当汽油被喷到阀门的背面时，碳就会积聚起来，并且蒸发得更慢。同时，经常怠速行驶时，进入发动机的空气流量很小，因此对积炭的侵蚀变得非常微弱，会促进积炭。

　　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.

　　注意火灾发生的时间

　　Pay attention to the time of fire

　　装有涡轮增压器的汽车，高速行驶或爬坡后，切勿立即失速，怠速10分钟后再失速。配备涡轮增压器的汽车形成碳沉积的速度比配备自然灵感的汽车快几倍。

　　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.

　　建议在满足所有日常维护要求的情况下，每2 ~ 4万公里不拆、不清洗进气系统。换句话说，在发动机不解体的前提下，应采用专用设备和专用方法对进气道、阀门、油路等容易形成积碳的车辆部件进行清碳。

　　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.

　　使用清洁汽油

　　Use clean gasoline

　　汽油中的杂质是形成碳沉积的主要成分，因此高清洁度汽油形成碳沉积的趋势较弱。然而，应该注意的是，高标签并不等于高质量。标签只代表油的辛烷值，而不是质量和清洁度。为了保证汽油的清洁，一些车主会在汽油中添加汽油清洁剂。这样可以有效的防止金属表面积碳层的形成，并能逐渐激活原有的积碳颗粒，慢慢的去除，从而保护发动机不受损坏。但是，汽油洗涤剂的添加一定要小心，如果添加假冒产品会得到相反的效果。

　　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.
