The significance of carbon deposition in diesel generator set
Diesel generator set carbon most users have never heard of this word, also don't know how this works. For technical personnel must know diesel generating sets, the concept of carbon deposition and the reasons of this phenomenon, and will handle and solve the problem.
The so-called diesel generator carbon deposition is actually the product of diesel oil and the incomplete combustion of the oil which enters the combustion chamber. A large amount of carbon accumulation will affect the performance of diesel generator set to a certain extent. The final performance is: poor combustion, worsening heat transfer and reducing the reliability of fuel injector.
Generating set the causes of formation are many, many, the author found that generating set according to the years of hands-on experience causes of carbon deposition mainly have six points:
1．Fuel injector work is not normal, such as poor atomization, drip, too high or too low injection pressure and injection time too early or too late, the fuel injection quantity is too much, will make some fuel incomplete combustion.
2．Oil is serious.
3．Air leakage is serious.
4．Cooling water temperature is too low, affect the normal combustion of the fuel.
5．Diesel oil and brand wrong, poor quality, formation of carbon residue after burning.
6．Diesel engine overload or temperature is too high, fire early to make the fuel combustion is not complete.
