1、柴油或機(jī)油雜質(zhì)多影響燃燒，或者牌號不對，不能在工作環(huán)境下正常流轉(zhuǎn)；

1. Excessive impurities in diesel or engine oil can affect combustion, or the brand is incorrect and cannot flow normally in the working environment;

2、環(huán)境溫度或冷卻水溫度過低，氣缸內(nèi)溫度達(dá)不到壓燃要求；

2. If the ambient temperature or cooling water temperature is too low, the temperature inside the cylinder cannot meet the requirements for compression ignition;

3、柴油機(jī)進(jìn)入氣缸內(nèi)的機(jī)油過多，影響燃燒，即竄機(jī)油問題，活塞、氣缸磨損過大，兩者間隙增加，不止影響氣缸內(nèi)燃燒壓力，還降低了機(jī)油刮走的能力，其他如活塞環(huán)損壞、氣門損壞等問題也是竄機(jī)油問題的常見故障；

3. Excessive oil entering the cylinder of a diesel engine affects combustion, which is known as oil leakage. The piston and cylinder wear is too large, and the gap between the two increases. This not only affects the combustion pressure in the cylinder, but also reduces the ability of oil to be scraped away. Other problems such as piston ring damage and valve damage are also common faults of oil leakage;

4、氣門密封效果不良、活塞與氣缸壁間隙過大引起的漏氣問題；

4. Leakage problems caused by poor valve sealing and excessive clearance between the piston and cylinder wall;

5、柴油發(fā)電機(jī)組過熱，如超載運行，提前著火，降低柴油燃燒質(zhì)量；

5. Diesel generator set overheating, such as overloading operation, early ignition, and reduced diesel combustion quality;

6、噴油器故障，包括噴油嘴滴油、噴油量過大、霧化不充分、噴油時間過早或過遲、噴油壓力不足或過壓等問題，都會影響柴油在氣缸內(nèi)的燃燒情況，柴油得不到足夠氧氣進(jìn)行燃燒。

6. Fuel injector failures, including nozzle dripping, excessive fuel injection, insufficient atomization, premature or delayed fuel injection, insufficient or overpressure fuel injection pressure, can all affect the combustion of diesel in the cylinder, and diesel does not receive enough oxygen for combustion.

發(fā)動機(jī)的積碳問題是長久以來存在的問題，即使是在規(guī)范操作的前提下，發(fā)動機(jī)長期運轉(zhuǎn)也可能出現(xiàn)少量積碳問題，未充分燃燒的碳顆粒聚集在排氣系統(tǒng)處，形成積碳，柴油發(fā)電機(jī)組以柴油發(fā)動機(jī)作為驅(qū)動，產(chǎn)生積碳也是其常見的故障之一。

The problem of carbon accumulation in engines has been a long-standing issue. Even under standardized operation, a small amount of carbon accumulation may occur during long-term operation of the engine. Carbon particles that are not fully burned accumulate in the exhaust system, forming carbon deposits. Diesel generator sets are driven by diesel engines, and carbon accumulation is also a common fault.
