Generally, the engine oil of the diesel generator set should be replaced once after 500h of operation, but sometimes the replacement period is not reached, or the engine oil has become thinner and impurities have increased within a short period of time, which makes it impossible to continue to use.

柴油發電機組機油為何會變質過快

Why the engine oil of diesel generator set deteriorates too quickly

①、機油牌號不對、質量達不到要求，一般增壓和標定轉速大于2000r/min的柴油發電機應選用CC級以上的機油；

① The engine oil grade is incorrect and the quality cannot meet the requirements. Generally, the diesel generator with supercharging and rated speed greater than 2000r/min should use the engine oil above CC level;

②、柴油機發電機技術狀況不好，竄氣、竄油、配合間隙過大或油溫過高；

② The diesel generator is in poor technical condition, with gas and oil leakage, too large fitting clearance or too high oil temperature;

③、柴油機發電機經常在低溫、低負荷、低速下運轉，活塞變形量不夠，燃燒不完全，有柴油沿缸壁進入油底殼使機油稀釋變質；

③ The diesel engine generator often operates at low temperature, low load and low speed. The piston deformation is not enough and the combustion is incomplete. Diesel enters the oil pan along the cylinder wall to dilute and deteriorate the oil;

④、廢氣進入油底殼凝結成水分和酸性物質，使機油變質；

④ Waste gas enters the oil pan and condenses into water and acid substances, which will deteriorate the engine oil;

⑤、機油濾芯臟，未經濾清的臟機油進入潤滑部位，加速了零件的磨損。

⑤ The oil filter element is dirty, and the unfiltered dirty oil enters the lubricating part, which accelerates the wear of parts.

⑥、濾芯密封圈破裂而發生內漏，一部分機油未經濾芯而直接通過濾清器而造成機油變質。

⑥ . The sealing ring of the filter element is broken and internal leakage occurs. Some engine oil directly passes through the filter element without passing through the filter element, causing deterioration of the engine oil.

柴油發電機組一般運行500h后應更換機油一次，但有時候未到更換期，或還沒用多長時間就出現機油變稀、雜質增多現象，無法繼續使用。

Why the engine oil of diesel generator set deteriorates too fast: the engine oil is of wrong brand and quality cannot meet the requirements. Generally, the diesel generator with supercharging and rated speed greater than 2000r/min should use the engine oil above CC level; The diesel generator is in poor technical condition, with gas and oil leakage, too large fitting clearance or too high oil temperature; The diesel engine generator often operates at low temperature, low load and low speed, the piston deformation is not enough, the combustion is incomplete, and diesel enters the oil pan along the cylinder wall to dilute and deteriorate the oil; The waste gas enters the oil pan and condenses into water and acid substances, which will deteriorate the engine oil; The oil filter element is dirty, and the unfiltered dirty oil enters the lubricating part, which accelerates the wear of parts.
