Background technology
More and more need to improve the fuel efficiency of automobile.Therefore, need have excellent fuel efficiency, low viscosity machine oil as lubricating oil composition (machine oil), be used for the engine of lubricated petrol motor vehicle or diesel-engine road vehicle.For example, having the SAE viscosity grade is that 5W20 and high-temperature high shear viscosity are (when velocity of shear or shearing rate are 10 6s -1The time measure numerical value at 150 ℃) be 2.6mPa.s machine oil since actual purpose for the fuel efficiency lubricating oil composition of the petrol engine of four-wheel drive vehicle.
But by being used for the four-stroke gasoline engine of motorcycle, machine oil also is used for lubricated transmission system and exists and may make energy driver such as transmitting gear wearing and tearing increase (wear resistance reduction) because engine oil viscosity reduces.Given this, JASO T903-2006 encourages to have 2.9mPas or higher high-temperature high shear viscosity (10 for the petrolic machine oil of motorcycle four-stroke 6s -1).Yet this high-temperature high shear viscosity is difficult in and obtains on the known SAE5W20 machine oil today, so the machine oil that uses in the motorcycle four-stroke petrol engine today is the low viscosity machine oil of SAEI viscosity grade 10W30,5W30 or 0W30.
On the other hand, consider the wear resistance that needs machine oil, ACEA C1-08 and C2-08, it is the European standard that is suitable for the machine oil of lubricated diesel-engine vehicles with diesel particulate filter, sets high temperature, the high-shear (10 of machine oil 6s -1) the following 2.9mPa.s that is limited to of viscosity, and in order to reduce the vaporization losses of machine oil, be limited to 13% on the NOACK vaporization losses.
Patent document JP (Kokai) 6-306384 discloses the lubricating oil that is used for the fuel economy of oil engine, wherein the organic molybdenum of predetermined amount joins in the oil of mineral oil basis, above-mentioned mineral oil basis oil has 3 to 5cSt dynamic viscosity in the time of 100 ℃, 135 or higher viscosity index and paraffin with respect to 90% or higher ratio (%Cp) of total carbon.
Patent document JP (Kohyo) 2003-505533 discloses lubricating oil composition, it is not have low volatility lubricating oil composition molybdenum additives, fuel economy, that have 15wt% or NOACK evaporation rate still less, comprise the calcium washing agent of predetermined amount and the oil soluble anti-wear agent of predetermined amount, and comprise the base oil of 50wt% mineral oil at least; In the time of 100 ℃, have 4.0 to 5.5mm 2The dynamic viscosity of/s; Comprise 95wt% or higher saturated product and 25% or naphthenic hydrocarbon still less; Have at least 120 viscosity index and 15.5wt% or NOACK evaporation rate still less.
Patent document JP (Kokai) 2000-87070 discloses the motorcycle four-stroke engine composition of excellent fuel-economy, and it has the effect that reduces fuel oil consumption, and it has 3 to 10mm when being included in 100 ℃ 2The dynamic viscosity of/s and 120 or the hydro carbons lubricant base of higher viscosity index, or mixed base oil comprises this base oil, zinc dialkyl dithiophosphate, metal detergent, ashless dispersant, wear adjustment agent and the viscosity index improver of at least 15 quality %, and its dynamic viscosity that makes said composition is 9.3 to 16.5mm in the time of 100 ℃ 2/ s.Definite says, it discloses the motorcycle four-stroke engine composition with SAE viscosity grade 10W30 or 10W40.
Summary of the invention
That yes is important as the approach that improves the motor car engine fuel efficiency to improve engine structure, but is known that also reducing oil body is effective for improving fuel efficiency.Therefore as previously mentioned, has the SAE viscosity grade and is 5W20 and high temperature, high-shear (10 6s -1) viscosity is that the machine oil of 2.6mPa.s is as the petrol engine oil of the fuel economy of four-wheel drive vehicle.Yet, the petrol engine oil that is used for the fuel economy of four-wheel drive vehicle has the SAE viscosity grade of 5W20, expect that it does not have the high temperature of 2.6mPa.s, shear viscosity, therefore problem is, when it is used as the petrolic machine oil of motorcycle four-stroke, machine oil is used for lubricated conducting system, and the problem of existence is that wear resistance is not enough.
The contriver is by finding that can produce lubricating oil composition has finished the present invention, and described lubricating oil composition has the SAE viscosity grade of 5W20 and the viscosity index in 140 to 230 scopes, 2.9mPa.s or higher high-shear (10 in the time of 150 ℃ 6s -1) viscosity, 13% or still less NOACK volatilization loss and excellent abrasive, described lubricating oil composition makes by using the base oil that for example has been fed in the recent period market and the amount of the combination of optimizing the binder component that joins described base oil and each emollient component, described base oil is mainly isoparaffin, have extremely high viscosity index wherein viscosity index in about 133 to 160 scopes and by hydrogenation and isomerization slack wax or the synthetic wax of producing by the Fischer-Tropsch method, distillation and dewaxing treatment obtain then.It should be noted that the SAE viscosity grade is that the lubricating oil composition of 5W20 is known and has an excellent fuel efficiency, because they all have relative low dynamic viscosity under low temperature and hot conditions.
Therefore, the present invention is the lubricating oil composition for automotive engine lubrication, it is the lubricating oil composition that comprises base oil and following additives component, and the SAE viscosity grade with 5W20, wherein viscosity index is in 140 to 230 scopes, 2.9mPa.s or higher shear viscosity in the time of 150 ℃, 13% or NOACK volatilization loss still less, described lubricating oil composition further comprises:
