After a long time use of diesel generator set, there will be carbon deposit in cylinder head and psiton if not maintain regularlly. Carbon deposit of generator set is a kind of hard material with strong adhesion and poor heat transfer performance. As the engine is used for a long time, the carbon deposits will accumulate in the combustion chamber, the top of the piston, the intake and exhaust ducts, etc. It not only hinders the heat dissipation of combustion chamber and piston, but also reduces the volume of combustion chamber and makes the engine work more rough. If the carbon deposit adheres to the intake and exhaust valves and their pipes, the exhaust will be blocked and the air intake will be insufficient; if the carbon deposit is formed at the head of the fuel injector, it is easy to block the injection hole and cause poor fuel atomization. Therefore, it must be removed during maintenance. The more advanced methods are ultrasonic cleaning and nuclea...
