Abstract
The invention provides an engine oil composition for improving oil loss or engine oil combustion of German automobiles. The engine oil composition comprises 63 to 78 weight percent of dodecyl carbon poly alpha-olefin base oil, 2 to 15 weight percent of ester base oil, 0.1 to 0.3 weight percent of pour point depressant, 8 to 10 percent of viscosity index improver and 10 to 13 weight percent of synthetic oil composite additive. The engine oil composition provided by the invention has low Noah gram value and low consumption in use, is not easy to produce 'engine oil combustion', reduces the adding times of engine oil, and reduces the maintenance expense at the same time of bring convenience to a driver. Proved by experiments, the Noah gram value of the engine oil composition is less than 4; and when the engine oil composition is used for an Audi series automobile with serious 'engine oil combustion', the engine oil is kept above the middle line by examination with an engine oil scale after the automobile runs for 5,000 kilograms.
Description
Technical field
The invention belongs to the ucon oil technical field, relate in particular to a kind of engine oil composition that German automobile is lost oil or burn oil phenomenon that is used to improve.
Background technology
Engine oil is described as automobile " blood ", can play effects such as lubricated, cleaning, cooling, sealing, anti-attrition to engine, reduces the wearing and tearing of engine part, prolongs its work-ing life.Engine oil is formulated by add additive in base oil, and base oil is the important component of decision engine oil performance.
Generally base oil is divided into mineral oil and synthetic oil, mineral oil is to obtain by physical method from crude oil, refines comparatively simply, can satisfy the performance requirement of most of engines; Synthetic oil obtains by chemosynthesis or refining method for processing; advantages such as having viscosity-temperature characteristics can be good, oxidation-resistance is strong, the high temperature resistance anti-shear ability is strong, the engine oil that preparation obtains have that use temperature is wide, usage period limit for length, lower viscosity can reach oil film and require, advantages such as the protection of engine is more comprehensive are had a good application prospect.
American Petroleum Institute (API) (API) is divided into five groups (API-1509) with base oil, and wherein, the 3rd group of base oil is owing to low price has obtained to use widely.But, the 3rd group of base oil of API mainly is to adopt hydrogenation technique to make, has higher viscosity index and Angelika Noack (Noack) value, therefore, Angelika Noack (Noack) volatility of the engine oil of the 3rd group of base oil preparation of employing API is higher relatively, the using time oil consumption is too fast, the phenomenon that " burn oil " occur, especially be applied to low power, high-speed and when being furnished with turbo charged German automobile, the too fast phenomenon of consumption of lubricating oil usually appears, need the frequent machine oil that adds, for the person for driving a car makes troubles.
Poly-alpha olefins (PAO) belongs to the 4th group of base oil in API-1509, have good viscosity temperature characteristic, low-temperature fluidity and lower volatility, is comparatively ideal base oil of preparation engine oil.Prior art discloses multiple engine oil by the preparation of PAO synthetic base oil, engine oil as the production of companies such as Mobil, FOX, shell, Castrol, the Angelika Noack value is relatively low, and consumption of lubricating oil is relatively slow in the use, is not prone to the phenomenon of automobile " burn oil ".But, this type of engine oil is generally formulated by eight carbon poly-alpha olefinss or ten carbon poly-alpha olefinss, the carbochain of eight carbon poly-alpha olefinss or ten carbon poly-alpha olefinss is short, thermal stability is relatively poor relatively, in hot environment, cracking takes place and causes the machine oil volatilization in carbochain easily, the person for driving a car still needs additionally to add machine oil, not only comparatively bothers, and also can increase cost of upkeep to the person for driving a car owing to the PAO synthetic base oil costs an arm and a leg.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of engine oil composition that German automobile is lost oil or burn oil phenomenon that is used to improve, and engine oil composition Angelika Noack value provided by the invention is lower, and consumption of lubricating oil is slower.
