We all know that when a generator breaks down, lubricating oil is used. Because the lubricating oil to the diesel engine body has a certain protective effect. Then, many people will have the idea that the use of lubricating oil, for the generator must be good. In fact, let Dongguan generator maintenance Xiaobian for you to explain the next.

Butter on dry cylinder liner of diesel engine will cause overheating of diesel engine and affect normal operation. The reason is that when the engine is heating up to the normal temperature, the cylinder liner will be heated and expanded, and the cylinder seat hole will expand less because the temperature of the cooling water is low.

Buttering the cylinder heads and pads to strengthen the seal is not worth the cost. After the cylinder head nut is tightened, part of the butter will be wasted out of 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 at high temperatures into carbon, the cylinder piston top and other places.

After the temperature of diesel engine rises, a layer of oil film between cylinder head and cylinder pad, cylinder head and cylinder surface will melt and disappear due to the temperature rise, so that the cylinder head nut back loose, resulting in air leakage, oil leakage, direct damage to the air cushion, may also be due to high temperature, butter coking, so that the cylinder head, cylinder pad is not easy to remove.
