Abstract
The invention discloses an engine lubricating oil, comprising the following substances by weight: 50-63 parts of base oil, 1.5-3.8 parts of polyoxyethylene nonyl phenyl ether, 1-7 parts of polyvinylethers, 11-18 parts of poly(alpha-alkene), 10-20 parts of ultra-high alkali synthesis calcium sulfonate, 1-3 parts of calcium alkylbenzene sulfonate, 1-3 parts of phosphinothioyl buoctyl-zinc salt, 1-7 parts of ethylene-propylene copolymer, 0.5-2.8 parts of oxymolybdenum dialkydithiophosphate, 0.02-0.7 parts of sulfurized calcium alkyl phenolate, and 0.00001-0.002 parts of methyl silicone oil ester. The beneficial effects reside in that: the engine lubricating oil has advantages of simple technology and low production cost; the engine lubricating oil has excellent antioxidation capability, high base number acidification resistance, abrasion resistance, effectively reduces evaporation loss amount of the lubricating oil, and improves abrasion caused by the prior lubricating oil on an engine; the engine lubricating oil has advantages of good detergency, high fuel value and complete combustion, enables the engine to reduce generation of greasy filth and carbon deposit, reduces discharge capacity of CO, hydrocarbon, NOx, sulfide and lead.
Description
Technical field
The present invention relates to a kind of engine oil.
Background technology
Along with the enhancing gradually of people's awareness of saving energy, countries in the world utilize problem more to pay attention to source.At present, in automobile industry, continually develop out fuel substitute automobile, wherein more satisfactory is with fuel such as compressed natural gas or liquefied petroleum gas (LPG), to replace the dual-fuel automobile of I. C. engine oil.
It is fuel that dual-fuel engine uses Sweet natural gas or liquefied petroleum gas (LPG), its calorific value is very high, exhaust emissions temperature is up to 480 ℃, than the temperature of common I. C. engine oil, exceed 180 ℃～200 ℃, engine combustion temperatures is high, causes lubricating oil evaporation loss large, NOx too high levels, I. C. engine oil very easily makes NOx that oxidation or nitration occur, and increases greasy filth and carbon deposit, thereby boost engine weares and teares, deterioration of lubricant is aging; And, the unlubricated effect of compressed natural gas or liquefied petroleum gas (LPG) self, therefore, require the ash content of I. C. engine oil moderate, make to be deposited on the ash content lubricate on valve and valve seating, ash content is too low, do not have lubrication, easily cause intake valve, vent valve and the prooving of valve seat, ash content is too high, can cause that the early stage igniting of engine and sparking plug pollute, affect engine power, in Engine Surface, generate hard settling, carbon deposit is too much, valve melting loss.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of engine oil.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of engine oil, the material that comprises following parts by weight: base oil 50-63 part, polyoxyethylene nonylphenol ether 1.5-3.8 part, polyvinyl ether 1-7 part, poly-α-alkene 11-18 part, high base number calcium alkylbenzenesulfonate 10-20 part, alkyl benzene calcium sulfonate 1-3 part, sulphur phosphorus fourth octyl group zinc salt 1-3 part, ethylene-propylene copolymer 1-7 part, dialkyl dithiophosphoric acid oxygen molybdenum 0.5-2.8 part, calcium sulfenyl phenolate 0.02-0.7 part, methyl-silicone oil ester 0.00001-0.002 part.
Preferably, described engine oil, comprises the material of following parts by weight: 60 parts of base oils, 2 parts of polyoxyethylene nonylphenol ethers, 5 parts of polyvinyl ethers, 11 parts of poly-alpha olefinss, 10 parts of high base number calcium alkylbenzenesulfonates, 1 part of alkyl benzene calcium sulfonate, 1 part of sulphur phosphorus fourth octyl group zinc salt, 3 parts of ethylene-propylene copolymers, 2 parts of dialkyl dithiophosphoric acid oxygen molybdenums, 0.25 part of calcium sulfenyl phenolate, 0.001 part of methyl-silicone oil ester.
The invention has the beneficial effects as follows: method technique is simple, and production cost is low; The raw material of selecting has extremely strong compatibility reasonableness, make dual-fuel engine lubricating oil ash content moderate, there is good resistance of oxidation, high base number acid-proof voltinism, abrasion resistance, effectively reduce the evaporation loss of lubricating oil, improve the wearing and tearing that lubricating oil causes engine in the past, thereby increased the work-ing life of engine, solved the aging fast problem of deterioration of lubricant, extend the drain period of lubricating oil, improved the power of engine; The detergency of this engine oil is good, fuel combustion value is high, burning completely, make engine reduce the generation of greasy filth and carbon deposit, CO, hydrocarbon polymer, NOx, sulfide and plumbous quantity discharged have been reduced, meet state's IV automobile exhaust emission standard, make engine reach the effect of efficient and energy-saving and emission-reduction.
