Imported bearing lubricating oil specific function and selection types

Import the specific function and choice of the type oil bearing grease what your role is? 1, the cooling: the oil to heat back into the sump to send out to the air, so, a few parts not too hot. 2, sealing leak proof: oil can form a seal between the piston and piston ring, to reduce the leakage of the gas and prevent pollutants enter from the outside. 3, cleaning cleaning: good oil to flush dirt on engine parts and back to the sump. Keep the parts surface is bright and clean. 4, lubrication antifriction: between piston and cylinder, spindle and bearing shell are there between the relative sliding fast, prevent parts wear when the main function of automobile engine oil. 5, shock absorption: when the engine cylinder pressure rise sharply, sudden intensification piston, piston, connecting rod and crankshaft bearing load is very large, after bearing lubrication, the load to bear impact load have the effect of the buffer. 6, rust corrosion: lubricating oil can adsorption in the surface to prevent water, air, acid, and harmful gas contact with the parts. The classification of engine oil: oil on the market at present because of the different base oil can Jane is divided into three (mineral oil and synthetic oil The vegetable oil for production scarce) 。 Among them, the synthetic oil across all the oil in one of the best the most expensive. The biggest difference is that: the temperature of the synthetic oil used more widely, the service life is longer, of course the price also higher; The same oil film, synthetic oil with low viscosity available can be reached, and mineral oil is used relative to the synthetic oil thicker viscosity to meet such requirement. Work in the same environment, the synthetic oil service life is longer than mineral oil because of the many, so the cost is higher, but after more oil change number, the total cost is not higher than light wu blue-chip many. So the owner can be used to compare.
