In fact, not only the function of the lubricating oil lubrication, but "a multitasker". Once they lose their effect or performance lower, will produce significant damage to the engine.
1. The lubrication by grinding: between the piston and cylinder, the spindle bearing and between the relative sliding there are fast, to prevent parts too fast to wear, the need for two sliding surface established between the oil film. Have enough oil film thickness of the relative sliding parts surface will be separated, so as to achieve the purpose of reducing wear.
2. Cooling cooling: oil to heat back to the fuel tank to send out to help in the air cooling water tank engine.
3. Wash clean: good oil to parts of the engine of carbide, sludge, wear, metal particles through the cycle back to the fuel tank, through the flow of oil, flush the working plane parts produced smudges.
4. Seal leak: the oil can be formed between piston ring and piston a sealing ring, reduce gas leakage and prevent outside pollutants into.
5. Rust and corrosion prevention: oil can absorb in parts surface, prevent water, air, acidity material and harmful gas and parts contact.
6. Vibration reduction buffer: when the engine cylinder inlet pressure rose sharply, suddenly aggravate the piston, piston flocks, and crankshaft connecting rod on the bearing load, the load bearing transfer after lubrication, the impact of the bear load get buffer.
