Abstract
The invention discloses a castor-oil-based ethanol fuel engine oil composition. Dioctyl sebacate and pentaerythritol ester, which are prepared from castor oil, are compounded into base oil, and a plurality of composite additives comprising a detergent, an antioxidant preservative, a dispersing agent, an antioxidant, an oiliness agent, an antirust agent, an antifoaming agent and a reinforcing agent are matched. According to the castor-oil-based ethanol fuel engine oil composition, a dense protective film is formed on the surface of a kinematic pair of an engine, so that the friction and abrasion of the kinematic pair of the engine can be effectively reduced, and the erosion of an ethanol fuel can be resisted; the composition has high low-temperature flowability, high-temperature oxidation resistance, acid neutralizing capability, detergency and dispersity, and the formation of oil sludge and carbon deposit is reduced; the composition has low volatility and emission performance and high antirust and anticorrosive performance, the power of the engine can be maintained, and the lubricating requirements of an ethanol fuel engine system can be met.
Description
Technical field
The invention belongs to explosive motor lubricant, especially castor-oil plant base ethanol fuel engine oil compositions field.
Background technology
Since 21 century, the diversification of the energy and vehicle fuel, renewable energy source and the clean alternative fuel such as exploitation and applied material energy, be the inexorable trend that solves mineral products short bunker, the protection of the environment that purifies air.Ethanol is common fuel oil energy substitute products, and it belongs to oxidizing combustible, close with the density of gasoline.These two kinds of fuel can directly mix dissolve each other (gasohol), directly apply on petrol motor, without the structure that changes engine, and can keep the performance of original engine.Therefore, the utilisation technology of alcohol fuel on petrol motor is own through quite ripe, and progressively to straight alcohol engine future development.
The gasification latent heat of ethanol is very large, while gasifying in cylinder, can absorb a large amount of heat, causes temperature cylinder to reduce.When motor speed is during lower than 1100r/min, engine, when idling operation, under the too low situation of temperature cylinder, is easy to cause flame-out of engine.For fear of the generation of this situation, must adjust engine structure.Due to the uniqueness of ethanol fuel engine, aspect lubricating oil selection, should slightly distinguish with fuel combustion type engine oil.Its main manifestations is that ethanol and products of combustion thereof are larger on the impact of regular gasoline machine oil coking amount; Can cause the high and low temperature dispersion coefficient of gasoline engine oil to reduce simultaneously; In addition alcohol fuel causes the easy coking of lubricating oil, and lubricating oil oil film is easily destroyed by ethanol in addition, causes cylinder wall, piston ring to be very easily worn.
Make full use of the physical resources of China's abundant, take Viscotrol C as raw material, new generation environmental protection energy-saving engine oil ingredient, not only can meet the use of ethanol fuel engine, reduce to greatest extent engine scuffing, increasing service life of engine, and can slow down the pressure of energy scarcity, significant to social sustainable development.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly forms fine and close protective membrane, effectively reduces friction and reduce wear, there are good low-temperature fluidity, oxidation-resistance and outstanding detergent-dispersant performance, prevent that oil product from generating greasy filth or carbon deposit, extends the work-ing life of engine; The castor-oil plant base ethanol fuel engine oil compositions that volatility is lower, antirust, anti-corrosive performance is good.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt dioctyl sebacate and pentaerythritol ester compound as base oil, coordinate multiple composite additive, its each constituent mass percentage ratio is:
