积碳对发动机的危害

Harm of carbon deposition to engine

结构损坏：

Structural damage:

气缸内构成燃烧室的各种结构是发生积碳的主要部位，有活塞顶部、火花塞、缸内喷油嘴、进排气门和进气管的气缸入口处。

Various structures constituting the combustion chamber in the cylinder are the main parts of carbon deposition, including piston top, spark plug, in cylinder fuel injection nozzle, intake and exhaust valve and cylinder inlet of intake pipe.

导致发动机性能下降

Cause engine performance degradation

重积碳导致动力下降的主要原因有：火花塞积碳减弱点火能力或引起点火失败，气缸漏气（气门处和活塞处）导致的压力下降等，在大负荷或者低转速时表现的比较明显。

The main causes of power drop caused by heavy carbon deposition are: carbon deposition of spark plug weakens the ignition ability or causes ignition failure, pressure drop caused by cylinder leakage (valve and piston), which is more obvious at high load or low speed.

耗油量上升

Increased fuel consumption

动力下降的同时还会伴有一定程度的耗油量升高，这是因为在获得和积碳影响前相同的动力时需要更大的节气门开度和增加相应的燃油供给。所以，出现原因不明的燃油消耗量增加时应该检查是否存在气缸积碳。

The decrease in power is accompanied by a certain increase in fuel consumption, which is due to the need for greater throttle opening and increased fuel supply when obtaining the same power as before the impact of carbon deposition. Therefore, when there is an unexplained increase in fuel consumption, check whether there is carbon deposition in the cylinder.

尾气污染物排放增加

Increased emission of tail gas pollutants

通常在对汽车进行年检时才会发现尾气中污染物排放增加。目前只检测一氧化碳、碳氢化合物和氮氧化物，积碳时三项指标都可上升或超标，这个变化可能比动力下降和耗油量增加出现的更早。

It is usually found that the emission of pollutants in the exhaust gas increases when the vehicle is inspected annually. At present, only carbon monoxide, hydrocarbons and nitrogen oxides are detected. During carbon deposition, the three indicators can rise or exceed the standard. This change may occur earlier than the decline of power and the increase of fuel consumption.
