The main reasons for carbon deposits in diesel generators include the following:
1. Abnormal operation of the 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, which will cause incomplete combustion of some fuel, thus forming carbon deposits.
2. Serious oil leakage: The oil leaks into the combustion chamber, resulting in incomplete combustion and carbon deposits.
3. Serious air leakage: Insufficient compression force in the cylinder, unable to generate high temperature, resulting in incomplete combustion of diesel and carbon deposits.
4. The cooling water temperature is too low: affecting the normal combustion of fuel and leading to the formation of carbon deposits.
5. The diesel and engine oil brands are wrong and the quality is poor: carbon slag is formed after combustion, leading to carbon deposits.
6. The diesel engine is overloaded or the temperature is too high: ignition is too early, resulting in incomplete combustion of fuel and carbon deposits.
7. The gap between the valve guide and the valve is too large, or the gap between the piston and the cylinder is too large, causing the oil to be sucked into the combustion chamber, resulting in incomplete combustion and carbon deposits.
8. Leakage and blockage of the intake and exhaust valves, or improper valve timing, etc., will also lead to a reduction in the air in the cylinder, resulting in incomplete combustion and carbon deposits.
9. The unit works under overload conditions, causing damage to parts, affecting normal operation, and increasing carbon deposits.
Understanding these reasons will help take appropriate measures to prevent and reduce the formation of carbon deposits, thereby ensuring the normal operation of the diesel generator and extending its service life.
