Problems solved by technology

[0003] As the manufacture of the engine becomes more and more sophisticated, the requirements for lubricating oil become more and more stringent. It is difficult for the existing engine oil to guarantee the normal operation of the engine, which leads to aggravated wear of the engine, serious corrosion of the piston ring and cylinder liner, and serious corrosion of the filter oil. Network clogged, oil change period shortened

[0052] Experimental example 1 Friction and wear test [SRV]

[0053] The test method is derived from SH / T0721. The friction and wear test of the present invention and several commercially available CJ-4 grade general-purpose diesel engine oils is carried out on a high-frequency linear vibration testing machine. The test conditions are: temperature 150°C, load 392N, frequency 50Hz, continuous The time is 60 minutes, and the result of table 2 shows that the friction coefficient of the engine lubricating oil composition of the present invention is obviously lower than other several co...

Abstract

The invention provides a molybdenum-containing engine lubricating oil composition which is characterized by being prepared from the following components in percentage by weight: A) 8-12% of a friction improver B) 0.5-1.1% of a compound with an indol-naphthyridine structural unit and C) 0.2-1.2% of a dithio compound, 8-12% of a compound antioxidant, 0.05-0.1% of an anti-foaming agent, 8-10% of a viscosity index improver, 13-18% of a diesel oil and engine oil compound agent, 10% of synthesized ester base oil and the balance of PAO (poly alpha olefins) base oil, totaling 100%. The molybdenum-containing internal combustion engine oil provided by the invention has the beneficial effects that 1) the oil draining period is prolonged from conventional 5000km to 50000km; and 2) the fuel is saved by 7-10%.

Description

technical field [0001] The patent of the present invention relates to a molybdenum-containing engine lubricating oil composition and a preparation method thereof. Background technique [0002] The engine is the heart of automobiles and many industrial equipments, and its lubricating oil consumption accounts for about 50% of the total lubricating oil. As the blood of the engine, engine oil plays the roles of lubrication, cooling, sealing, cleaning, anti-rust and anti-corrosion, etc. It is a functional liquid to maintain the long life and efficient operation of the engine. [0003] As the manufacture of the engine becomes more and more sophisticated, the requirements for lubricating oil become more and more stringent. It is difficult for the existing engine oil to guarantee the normal operation of the engine, which leads to aggravated wear of the engine, serious corrosion of the piston ring and cylinder liner, and serious corrosion of the filter oil. The grid is clogged and t...
