1. Cooling and cooling: The oil can bring heat back to the oil tank and then to the air. In this way, several parts will not be heated too high. 3, cleaning and cleaning: good oil can be dirt on the engine parts washed and brought back to the oil tank. Keep the surfaces of all parts clean and smooth. 4. Lubrication and abrasion reduction: There is a rapid relative slip between the piston and the cylinder, between the spindle and the bearing, to prevent the main effect of the vehicle oil when the various parts wear out. 5, shock absorption buffer: When the engine cylinder port pressure rises sharply, suddenly increase the load on the piston, piston crumbs, connecting rod and crankshaft bearings, this load is transmitted through the bearing lubrication, so that the impact of the shock load to play a buffer role . 6, rust and corrosion: Lubricating oil can suck on the surface of the parts to prevent contact with water, air, acidic substances and harmful gases and parts. Motor oil classification: At present, the oil on the market can be simply divided into three kinds of mineral oil and synthetic oil because of the difference of its base oil (vegetable oil is not considered due to the scarcity of output). Among them, the best and most expensive of all oils in synthetic oils. The biggest difference between the two is that the synthetic oil has a wider temperature, a longer service life, and of course, a higher price. With the same oil film requirements, the synthetic oil can be achieved with a lower viscosity, and the mineral oil needs to be used relative to the synthesis. Thicker oil viscosity can meet this requirement. In the same working environment, synthetic oil has a longer lifespan than mineral oil, so the cost is higher, but after the number of oil changes, the total cost is not much higher than that of Guangwu. Therefore, the owner can use it comparatively. CNC Aluminum Spare Part is those parts manufactured by CNC machine directly.It can greatly save the tooling cost if the required quantity of the parts is only in sample stage.CNC Aluminum Spare Part is precise in the dimension and the cutting burr is perfect.Also CNC Aluminum Spare Part surface can be better protected .It can fabricate small size Aluminum Sheet or spare parts. CNC Aluminum Spare Part is more precise of external dimension. The tolerance of the size is very small.

2, sealed leak-proof: oil can form a seal between the piston ring and the piston to reduce gas leakage and prevent the entry of contaminants from the outside world.
