We all know that when generators fail, they always use lubricants. Because lubricating oil has a certain protective effect on the body of the diesel engine. Well, many people will have the concept that using lubricants will definitely be good for generators. In fact, let me explain to you the editor of Dongguan Generator Maintenance.

Butting the dry cylinder liner of a diesel engine will cause the diesel engine to overheat and affect normal operation. The reason is that when the engine is heated to a normal temperature, the cylinder liner will be thermally expanded, and the cylinder seat hole will have a smaller expansion due to the lower temperature of the cooling water.

Cylinder heads and gaskets are greased to enhance the seal. After the cylinder head nut is tightened, part of the butter will be wasted outside the cylinder and part of the butter will be squeezed into the cylinder. When the diesel engine is working, this part of the butter will be burned into charcoal at high temperature and accumulated on the top of the piston of the cylinder.

After the temperature of the diesel engine rises, a layer of oil film between the cylinder head and the gasket, the cylinder head and the surface of the cylinder body will melt and disappear due to the increase in temperature, thereby loosening the cylinder head nut, causing air leakage and oil leakage, which is straight. When the air cushion is damaged, the cylinder head and the cylinder cushion may not be easily removed due to the high temperature and the scorching of the butter.
