1. Abnormal operation of the fuel injector, such as poor atomization, dripping, high or low injection pressure, as well as early or late injection time, and excessive injection volume, can cause incomplete combustion of some fuels.

2、竄機油嚴重；

2. Severe oil leakage;

3、漏氣嚴重；

3. Severe 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. Diesel and engine oil have incorrect grades, poor quality, and form carbon residue 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. Diesel engines are overloaded or overheated, causing premature ignition and 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 in diesel generator sets, nor do they know how 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 carbon deposit in the Diesel generator is actually the product of incomplete combustion of diesel oil and engine oil flowing into the combustion chamber. It is a common phenomenon to produce carbon deposits on the top of the piston, combustion chamber wall and around the valves of the diesel engine. A large amount of carbon deposition will affect the performance of the diesel generator set to some extent, and its final performance is: poor combustion, heat transfer deterioration and reducing the reliability of the fuel injector.
