Influence of Water Content on the Performance of Engine Oil for Hybrid Vehicles
Distilled water is evenly dispersed in engine oil using a mechanical stirrer to form a stable emulsion with a water-in-oil structure.The effects of water content on the physicochemical properties of hybrid vehicle engine oil were evaluated using the low-temperature pumping viscosity test for petroleum products,copper strip corrosion test,oxidation induction period test for lubricating oils,pour point test,and four-ball method.The experimental results show that water has an impact on the low-temperature pumpability viscosity,oxidation induction period,maximum non-seizure load,weld load,and wear scar diameter of the oil products,and as the water content increases,the low-temperature fluidity,oxidation resistance,load-bearing capacity,and wear resistance of the oil product deteriorate;while the pour point and corrosion of oil product are basically unaffected.(Charts0 Tables5 References5)
