Abstract
The invention discloses a self-repairing and frictional-resistance-reducing lubricating oil composition for an engine. The lubricating oil composition contains a plurality of fine alloy particles, wherein the alloy particles are synthesized by specially smelting copper, lead and silver, and adding an antioxidant, an anti-rusting agent, a detergent dispersant and base oil. Under the action of a high-temperature and high-pressure strong friction force, contact points between the alloy particles and a machine metal surface are deformed when a pressure stress exceeds the yield limit thereof and extrude and damage an oil film and an oxide film at the contact points to expose pure metals; and the two metal molecules mutually attract, diffuse and rebuild the metal surface in a metal molecule diffusion welding way. The friction coefficient is greatly reduced; the viscosity index and the adhesive capacity of the engine oil are improved, and the engine oil synergistically acts with a dynamic protective layer so as to keep the engine always in a good lubricated state under any condition and avoid dry friction and half dry friction generated when the engine is coldly started; and vehicle exhaust emission is improved and fuel is saved.

Embodiment
A kind of alloy particle that is used for the lubricating oil composition with selfreparing and reduction friction resistance of engine, with lubricating oil is carrier, in oiling system, circulate, arrive each surface of the work of engine, and build up in machine members, scuffing, crackle etc. and locate, under the effect of the strong frictional force of High Temperature High Pressure, when the point of contact of alloy particle and parts metallic surface surpasses its yield strength in stress, produce viscous deformation, and the oil film and the oxide film at this place of squeeze and destroy, clean metal exposed.Attract each other, spread between two metallic molecules and, remake the metallic surface in metallic molecule diffusion welding mode; Change the fricting movement form, made original mobile friction become rolling resistance, greatly reduced frictional coefficient; Improve the viscosity index and the adhesive capacity of machine oil,, make engine under any circumstance all be in good lubricating status, metal to-metal contact that has produced when having avoided engine cold-start and semi-dry friction all the time with the dynamic protective layer synergy; Improve motor vehicle exhaust, fuel saving.
Behind the engine start, alloy particle enters oiling system, immediately by temperature, pressure and frictional force, utilize the metallic molecule diffusion, the automatic searching comprises generation friction position in all oiling systems such as cylinder, big or small bearing shell, valve, to scuffing, crackle, the abrading section, fill up, repair, fill up, repair and remake firm metallic surface incessantly, until reaching or approaching the new car design tolerance.After reaching the new car design tolerance, because gap smaller, it is big that friction pressure becomes, and this moment, the abrasion loss of abrading section approached the reparation amount that alloy particle is filled up, thereby reached a kind of dynamic balance, made reparation can not surpass original design tolerance.Alloy particle is welded in the friction surface of the work and forms dynamic protective layer, and friction is carried out in the protective layer of two surface of the works, abrasive parts using itself no longer, and the wearing and tearing to machine members and repair layer simultaneously keep continual reparation.All the time safeguard the integrity and the design tolerance of surface of the work, make dynamic property, economy, the working reliability of engine keep the peak state.
Base oil with 90.5%, to be poly ﹠ Alpha ,-olefin oil smelt synthetics, 1% antioxidant, 1% rust-preventive agent, 1.5% detergent dispersant with 6% copper, lead, silver to this base oil composition colludes at normal temperatures and pressures becoming to have selfreparing and reduce the lubricating oil composition of friction resistance, and maximum mean particle dia is less than 16 microns alloy particle metal additives.Wherein three kinds of metals are smelted the alloy cpd that forms with 3: 1: 6 formulated component by mechanical alloying (Mechanical Alloying is called for short MA); With impact, the collision by long fierceness between powder particle and the abrading-ball in high-energy ball milling of metal or alloy powder, make powder produce cold welding, fracture repeatedly, cause powder particle Central Plains handset tool alloying, realize the process of solid alloyization with high-energy mills or ball mill, thereby form the small spherical soft metal particulate of Subnano-class.
A kind of lubricating oil composition with selfreparing and reduction friction resistance is applicable to all four-stroke vapour, diesel motor, as the engine of automobile, tractor, motorcycle, engineering machinery, train, boats and ships, generating set and various mechanical means.We use at home and comprise various vapour bavin vehicles, engine, and 184 tons mine vehicle, motorcycles etc. are all obtained remarkable effect, prolong 3～5 times of engine lives.Charging method is changed oil identical with the machine oil of regular engine oil.
As follows after using 1,000 kilometers to the statistic data of engine cylinder pressure:
Use this lubricating oil composition to travel after 1000 kilometers to different automobile types, vehicle engine pressure measured and do not used this lubricating oil composition front engine cylinder pressure to compare as following table:
| Vehicle | Do not use front air cylinder pressure (kg/cm 2) | Use exhaust hood pressure (kg/cm 2) |
