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、窜机油严重；

2. Severe oil leakage;

3、漏气严重；

3. Severe air leakage;

4、冷却水温度过低，影响燃料的正常燃烧；

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

5、柴油与机油牌号不对，质量差，燃烧后形成炭渣；

5. Diesel and engine oil have incorrect grades, poor quality, and form carbon residue after combustion;

6、柴油机超载或温度过高，着火过早，使燃料燃烧不完全。

6. Diesel engines are overloaded or overheated, causing premature ignition and incomplete fuel combustion.

柴油发电机组积碳这个词大多用户都没听说过，也不知道这是怎么一回事。而对于技术人员来说就必须要知道柴油发电机组积碳的概念和产生该现象的原因，并且还要懂得处理和解决该问题。

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.

所谓柴油发电机积碳实际上是柴油和窜入燃烧室的机油不完全燃烧的产物，在柴油机活塞的顶部、燃烧室壁和气门周围产生积炭是较为常见的现象。大量的积炭会对柴油发电机组的性能是由一定的影响的，其更终的表现是：使燃烧不良、传热恶化并降低喷油器工作的可靠性。

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.
