積碳對發(fā)動機(jī)的危害

Harm of carbon deposition to engine

結(jié)構(gòu)損壞：

Structural damage:

氣缸內(nèi)構(gòu)成燃燒室的各種結(jié)構(gòu)是發(fā)生積碳的主要部位，有活塞頂部、火花塞、缸內(nèi)噴油嘴、進(jìn)排氣門和進(jìn)氣管的氣缸入口處。

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.

導(dǎo)致發(fā)動機(jī)性能下降

Cause engine performance degradation

重積碳導(dǎo)致動力下降的主要原因有：火花塞積碳減弱點火能力或引起點火失敗，氣缸漏氣（氣門處和活塞處）導(dǎo)致的壓力下降等，在大負(fù)荷或者低轉(zhuǎn)速時表現(xiàn)的比較明顯。

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

動力下降的同時還會伴有一定程度的耗油量升高，這是因為在獲得和積碳影響前相同的動力時需要更大的節(jié)氣門開度和增加相應(yīng)的燃油供給。所以，出現(xiàn)原因不明的燃油消耗量增加時應(yīng)該檢查是否存在氣缸積碳。

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.

尾氣污染物排放增加

Increased emission of tail gas pollutants

通常在對汽車進(jìn)行年檢時才會發(fā)現(xiàn)尾氣中污染物排放增加。目前只檢測一氧化碳、碳?xì)浠衔锖偷趸?，積碳時三項指標(biāo)都可上升或超標(biāo)，這個變化可能比動力下降和耗油量增加出現(xiàn)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.
