1. The abnormal operation of the fuel injector, such as poor atomization, oil dripping, too high or too low injection pressure, too early or too late injection time and too much injection volume, will make some fuel burn incompletely.

2、竄機油嚴重；

2. Serious oil channeling;

3、漏氣嚴重；

3. Serious air leakage;

4、冷卻水溫度過低，影響燃料的正常燃燒；

4. The cooling water temperature is too low, which affects the normal combustion of fuel;

5、柴油與機油牌號不對，質量差，燃燒后形成炭渣；

5. The grade of diesel oil and engine oil is wrong, the quality is poor, and carbon residue is formed after combustion;

6、柴油機超載或溫度過高，著火過早，使燃料燃燒不完全。

6. The diesel engine is overloaded or the temperature is too high, and the ignition is premature, resulting in incomplete fuel combustion.

柴油發電機組積碳這個詞大多用戶都沒聽說過，也不知道這是怎么一回事。而對于技術人員來說就必須要知道柴油發電機組積碳的概念和產生該現象的原因，并且還要懂得處理和解決該問題。

Most users have never heard of the word "carbon deposition of diesel generator set" and do not know what it is. For technicians, they must know the concept of carbon deposition in diesel generator sets and the causes of this phenomenon, and also know how to deal with and solve this problem.

所謂柴油發電機積碳實際上是柴油和竄入燃燒室的機油不完全燃燒的產物，在柴油機活塞的頂部、燃燒室壁和氣門周圍產生積炭是較為常見的現象。大量的積炭會對柴油發電機組的性能是由一定的影響的，其更終的表現是：使燃燒不良、傳熱惡化并降低噴油器工作的可靠性。

The so-called diesel generator carbon deposition is actually the product of incomplete combustion of diesel and engine oil entering the combustion chamber. Carbon deposition is a common phenomenon on the top of diesel engine piston, combustion chamber wall and around valve. A large amount of carbon deposition will have a certain impact on the performance of diesel generator set. Its final performance is to make poor combustion, deteriorate heat transfer and reduce the working reliability of fuel injector.
