Butter is widely used in diesel generators to protect the engine body, but should not be abused. Otherwise, it will lead to bad results, cause reaction and damage the engine body. Why not butter dry liner, cylinder head and gasket?
Grease coating of diesel dry cylinder liner will affect the normal operation of diesel engine overheating. Because when the engine temperature rises to normal, the cylinder liner gets hot and the seat holes in the cylinder seat are cooled by the coolant, which expands slightly. The outer surface of the dry cylinder liner is pressed against the seat hole, releasing heat. Grease coating outside the cylinder liner prevents good contact between the two sides and can not dissipate heat normally. Do not butter the cylinder head and gasket. Because after tightening the cylinder head nut, part of the Greek is pushed out of the cylinder, waste, part of the Greek is pushed out of the cylinder. When the diesel engine is working, this part of the grease burns at high temperature, and the top of the charcoal, cylinder and piston accumulate. When the temperature of the diesel engine rises, the oil film between the cylinder head and cylinder pad, the cylinder head and the surface of the cylinder head disappears with the temperature rising, the cylinder head nut becomes loose, the air leaks, and the cylinder pad is damaged directly. High temperatures and Greek coking can also make cylinder heads and gaskets difficult to remove.
