Some important maintenance methods for repairing generator cylinder head faults are summarized as follows:


1. If the generator set sleeps until it breaks through and leaks due to water shortage and high temperature, it is likely to cause cracks in the cylinder head valve seat ring, and the copper sleeve rubber ring of the fuel injector melts at high temperature. The cylinder head that produces the cracks should be scrapped and disposed of.


2. The copper sleeve and rubber ring of the fuel injector may be damaged after prolonged operation. For water on the oil pan or piston top, the bottom plane of the cylinder head should be checked for cracks, and the copper sleeve and rubber ring of the fuel injector should be checked for damage.


3. If serious oil leakage is found in the cylinder head of the generator set before maintenance, the surface of the cylinder head should be ground during maintenance. The maximum grinding amount of the cylinder head is 1mm, and it is recommended to limit each grinding amount to 0.10mm as much as possible. The minimum thickness of the N-series cylinder head is 110.24mm, while the minimum thickness of the K-series cylinder head is 119.76mm.


4. During the overhaul of the generator set, a comprehensive inspection should be conducted on the water blockage of the generator set cylinder head. If there is any damage to the water blockage, it is recommended to replace all the water blockage of the entire cylinder head.
