Poly- a alkene PAO 4: such oil product is synthetic oil, in anti-oxidant, lubricity, hydrolysis stability, cold starting property, guarantor
It is all very good for protecting in the performances such as performance, noise-proofing, mainly improves the performance indicator of various aspects using 35% proportion, especially
It is that can be improved oil product lubrication and protective effect in lubrication protection performance, to achieve the effect that fuel-efficient, it is low followed by improves its
Warm cold starting performance can possess good cold starting property etc., in the case where subzero 35 DEG C so as to improve the comprehensive of oil product
Can, the disadvantage is that poor to additive solubility property.
Abu Dhabi 4CST: such oil product is API Group III oil, is hydroisomerization oil product, mainly meets oil product
Low-temperature cool starting and low temperature pumpmg quality, are added this oil product, exactly possess better low temperature fluidity.
Trihydroxymethylpropanyl ester: such oil product is API V class oil, belongs to high-grade synthetic ester lubricant, the performance of such oil product:
There is good solubility property to additive, increase the polarity of oil product, can be improved oil product to metal adhesion, increase subtracting for oil product
Rubbing property improves the antioxygenic property of oil product, reaches the service life for extending oil product, but should not add, is primarily due to this oil product
Hydrolysis stability is poor, is easy to happen hydrolysis.
Viscosity index improver uses hydrogenated styrene copolymer SV261: this allows for it and possesses good shear stability (SSI 20
Left and right), and low temperature fluidity is also relatively good, and dosage is added to reach 11.5%, mainly use low fraction base oil, viscosity compared with
Small, mainly consideration CCS must be smaller than 6200.
The functional complexing agent of Ya Fudun 9490: this is a novel composite functional additive, and additional amount 10.1% accords with
The specification certification of API SN and GF-5 and dexos1 is closed, it is comprehensive to the peace and quiet dispersion of engine oil, wear-resistant antioxygen, antirust etc.
The raising of energy.Mainly meeting U.S.A is automobile energy-saving requirement.
Nano boric acid lanthanum antifriction and antiwear agents: this is a functional strengthening agent, can be improved film strength, improves friction,
Frictional resistance is reduced, and there is certain antioxygen, wear-resistant, anticorrosive and detergent-dispersant performance, and than existing market sulphur phosphorus antifriction
Agent small toxicity has good protective effect to tail gas treatment device, extends the service life of exhaust gas processing device, in engine oil
It is middle to be added 0.5%.
Luo Mankesi V1-248 pour-point depressant: main performance is the pour point for reducing oil product, improves the cryogenic property of oil product, is added
0.3-0.5% depression effeCt is best.
Composite anti-foaming agent 1: it is the compound defoaming agent of no silicone oil, to having good improvement on the antifoam property of oil product,
Especially there is preferable improvement in its air release property, this is the reinforcement to oil product antifoam property, and additional amount should not be excessive, excessively
It will lead to oil product muddiness.
A kind of gasoline engine oil formula can promote the effective power of engine, reduce the discharge of exhaust particulate object, use the longevity
Life length, pour point is low, and viscosity index (VI) is high, and fuel economy is good, has degradability, reduces the harm to environment, and coefficient of friction is low, oil
The bearing capacity of film is high, can self-healing wear surface, extend the service life of engine.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
