Description

Lubricant composition for four-stroke motorcycle engine and its manufacturing method
Technical field
The present invention relates to a kind of Lubricant composition for four-stroke motorcycle engine.Specifically, the present invention relates to one kind Detergent-dispersant performance can be with the excellent Lubricant composition for four-stroke motorcycle engine of abrasion resistance.
Background technique
In general, the transmission mechanisms such as the engine of automobile and speed changer, clutch are to separate lubrication, and four strokes rub All functional components of motorcycle engine design for barrel type crankcase.Four-stroke engine for motor cycle lubricating oil is used for simultaneously The profit of the moving parts such as multi-disc wet clutch, high speed and transmission gear, shift mechanism and piston, cylinder, air inlet and exhaust valve It is sliding that it is necessary to have excellent comprehensive performances.Compared with four stroke automobile engines, the output power of four-stroke engine for motor cycle Higher, working condition is harsher, and not only revolving speed is fast but also operating temperature is high.Wherein, the peak power output of 4 stroke motorcycle It is 1.3~1.8 times of automobile up to 45~140kW/L, and revolving speed is up to 6000~20000rpm when peak power output 1.3~2 times of automobile.Due to most of motorcycles be all made of it is air-cooled so that the operating temperature of engine is sometimes up to 160 DEG C. In addition, fuel is sucked engine cylinder by negative pressure by motorcycle engine, the lubricating oil and fuel of sucking burn simultaneously, and heat is negative Lotus is high, and easily stagnant attached generation deposit is deposited on piston and cylinder, leads to piston ring scuffing and get rusty, sealing function decline, Connecting rod and main bearing lubrication failure.
In recent years, four-stroke engine develops towards high performance, high power direction, to four-stroke engine lubricating oil Performance requirement it is also increasingly harsh.Especially high-performance four rushes car engine, pursues miniaturization, lightweight and high power, Asking can run well for a long time under the extremely harsh high speed conditions such as carriage 10000rpm, cart 20000rpm, It is contemplated that arrive the durability of engine, this requires four-stroke engine for motor cycle lubricating oil not only have it is splendid wear-resistant Property, excellent thermo oxidative stability and high temperature detergency, be also required to efficiently remove the deposit on engine components, prevent Only greasy filth generates, to protect engine injury-free under severe conditions.
Seek more efficiently antioxidant additive and develops the four-stroke engine for motor cycle lubricating oil of novel high-performance, one It is directly the target that those skilled in the art make great efforts.
United States Patent (USP) US 5304314A discloses a kind of phenolate conjunction for being suitable as sulfur-bearing and arylamine that antioxidant uses Object.United States Patent (USP) US 2006/0189824A1 discloses a kind of shielding phenol containing secondary aromatic amine for being suitable as antioxidant and using Compound.
But the compound of these prior arts in four-stroke engine for motor cycle lubricating oil in use, the height of oil product Warm antioxygenic property, detergent-dispersant performance energy and abrasion resistance still remain room for improvement.In addition, in addition to the unfavorable shadow of deposit Other than sound, the corrosion of engine also can serious curtailment engine service life, and the corrosion of some key positions is largely On also influence the performance of operating condition of engine.The prior art is also far from enough to the concern of rustless property.
Therefore, a kind of Lubricant composition for four-stroke motorcycle engine is still required in the prior art, is not only able to full The requirement increasingly harsh to high-temperature oxidation resistance of the current more high standard product of foot, and also show excellent detergent-dispersant performance Energy, abrasion resistance and rustless property.
