Which parts of the diesel engine are allergic to butter?
Butter is widely used in diesel engines to protect the body, but it cannot be abused. Otherwise, it will cause adverse consequences, and it will even adversely affect the body. The application of butter to 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 up to normal temperature, the cylinder liner will be thermally expanded, and the cylinder block seat hole will have a smaller expansion due to the lower temperature due to the cooling water. The outer surface of the dry cylinder liner fits snugly over the seat hole to conduct heat. The buttering of the cylinder liner prevents good contact between the two surfaces and does not allow proper heat dissipation. The cylinder head and cylinder gasket should not be buttered to enhance the seal. The reason is that after the cylinder head nut is tightened, some of the butter will be wasted outside the cylinder and some 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 a high temperature, accumulating at the top of the cylinder piston, etc. After the diesel engine temperature rises, a layer of oil film between the cylinder head and the cylinder head gasket, the cylinder head and the cylinder block surface will melt and disappear due to the increase of temperature, so that the cylinder head nut will loosen, causing leakage, oil leakage, and direct Damage to the cylinder head gasket may also be due to the high temperature and the coking of the butter, making the cylinder head and cylinder head gasket difficult to disassemble.
