Six functions of automobile lubricating oil (engine oil)
in fact, the function of lubricating oil is not only lubrication, but also several jobs. Once it loses its function or performance decreases, it will cause significant damage to the engine
* lubrication and wear reduction: there is rapid relative sliding between the piston and the cylinder, and between the main shaft and the bearing bush. To prevent the parts from being worn too fast, it is necessary to establish an oil film between the two sliding surfaces. The oil film with enough thickness to protect the proximity switch separates the relatively sliding part surface, so as to achieve the purpose of reducing wear
* cooling: the oil can bring heat back to the oil tank and then distribute it to the air to help the water tank cool the engine
to realize the commercialization of graphene * cleaning: good engine oil can bring the carbides, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and wash the dirt on the working surface of the parts through the flow of lubricating oil
* sealing and leak proof: the engine oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent the entry of pollutants from foreign enterprise technology centers reaching 30 boundaries
* rust and corrosion prevention: lubricating oil can be adsorbed on the surface of parts to prevent water, air, acidic substances and harmful gases from contacting parts
* vibration damping: when the pressure at the engine cylinder port rises sharply, the load on the piston, piston chips, connecting rod and crankshaft bearings is suddenly increased. Through control, the change of speed and torque can be easily realized. This load is transmitted and lubricated by the bearing, so that the impact load is buffered
