Description
The present invention relates to the lubricated and packing technique of cylinder of internal combustion engine and valve, particularly can produce the solid lubricant particulate to improve lubricated and the alloy and the device that seal of cylinder.
Chinese patent 86102893 discloses a kind of alloy that improves motor performance of Shenyang Smeltery Factory invention, this alloy is by tin, plumbous, indium, gallium is smelted in crucible by suitable proportioning and is formed, be characterized in that matter is crisp, hardness is little, easy to wear, in use, be placed in the fuel tank, because jolting and velocity variations during automobilism, cause the friction of alloy block and tank wall, the alloy abrasive dust (particulate) that produces is suspended in the gasoline, along with gasoline enters cylinder, in the fuel combustion process, alloy particle is atomized and is sprayed on the casing surface, on the surface of friction of piston ring and cylinder, form solid lubricant film, thereby improved the lubricated and sealing of cylinder, improved the power and the emission behavior of engine.Yet there are many defectives in this technology, mainly is: one, and for obtaining more alloy abrasive dust (particulate), require alloy easy to wear producing a large amount of alloy particles, so the hardness of alloy designs (about HV
0.56～9), fusing point (about 120 ℃～150 ℃) is on the low side, so just causes alloy very easily to run off, particularly when near the high temperature low regime of the piston motion top dead center, alloy will melt and make lubricity decline; Its two, abrasive dust (particulate) diffuses to fuel tank, again from the fuel tank to the cylinder, process is long, and it is slow to take effect, and mix with greasy dirt the bottom that must have considerable alloy particle to be deposited on fuel tank, part reduces the lubrication and seal effect again for various filter blocks cause waste; Its three, lead content is up to 30% in the alloy, there is serious Lead contamination in exhaust emissions, and lead is the principal element of design this alloy low melting point, soft, therefore this pollution can't be got rid of.For another example, the Chinese patent 89107075.3 disclosed alloy balls that improve motor performance and discharging, its contribution only is alloy block is placed in the porous hollow spherical shell, when the porous hollow spherical shell rolls in fuel tank, mutual friction mutually between alloy block and spherical shell, alloy block and the alloy block, can produce more alloy abrasive dust (particulate), as for the bismuth that in alloy, increases by 5%～10%, just, do not improve the defective that above-mentioned Chinese patent 86102893 is had in order further the fusing point of alloy to be reduced to 110 ℃～120 ℃.
The objective of the invention is to for overcoming the defective of above-mentioned technology, designed a kind of postadhesion that atomizes wear-resistant on cylinder inner wall, be difficult for to run off and do not have the alloy of Lead contamination, and can provide enough above-mentioned alloy particle and loss is little, the device of instant effect.
Purpose of the present invention realizes by following measure: the alleged alloy of the present invention has the microstructure of similar bearing metal, it is disperse distribution hard point in the soft matrix, therefore frictional coefficient is low and have certain intensity and a wear resistance, this alloy is by tin, indium, gallium, antimony, the melting in the crucible resistance furnace of copper and rare earth cerium forms, distribute by weight, tin accounts for 50～66%, indium accounts for 20～35%, gallium accounts for 5～10%, antimony accounts for 3～5%, copper accounts for 1.9～4%, cerium is less than 0.1%, wherein, tin, indium is soft matrix, gallium mainly is distributed on the crystal boundary, add antimony, copper can obviously improve the intensity and the wear resistance of alloy, and impel generation second precipitation mutually, and the rare earth cerium then is used to improve the antioxidant property of alloy, and the fusing point of alloy is controlled at 160～200 ℃, be higher than piston ring and cylinder wall working temperature at the interface, alloy rigidity is HV in the time of 20 ℃
0.5kg8～12.
Because above-mentioned alloy wear-resisting is good, therefore enough alloy particle is ad hoc has counted a device in order to provide.Acceleration frequent when considering engine operation mainly vertically takes place, according to these characteristics, this device utilizes this vibration of engine to produce abrasive dust (particulate), simultaneously in order to shorten the flow process of alloy abrasive dust, connect on oil inlet pipe, with oil the alloy abrasive dust is directly brought in the cylinder, thereby avoided unnecessary loss.This device is had the housing, end cap of tube stub, is that a pair of mass, the compression spring of end face formed with the alloy by two ends, the end cap closure casing forms an airtight container, compression spring is connected to an integral body above-mentioned container of packing into a pair of mass, the alloy end face of mass can be close to the inwall slip of end cap under the tension force effect of compression spring, and tube stub is serially connected in this container in the preceding in-line of engine and carburetor vertically.
When engine operation, because the vibration of vertical direction, alloy and end cap rub, produce alloy abrasive dust (particulate), alloy also constantly reduces, but under the effect of compression spring, the alloy end face of mass can keep in touch with the end cap inwall all the time, and the oil in the oil circuit is sent into alloy abrasive dust (particulate) in the oil cylinder by tube stub.
Select rigidity, the weight of mass and the roughness of end cap inner wall surface of compression spring, can change the turnout of alloy particle.
Advantage of the present invention:
1. lubrication and seal is effective.Alloy melting point that the present invention is alleged and wear resistance are higher than the alloy in the prior art scheme, advantages of high bearing capacity is arranged under the high temperature on the surface of friction of cylinder and piston ring, particularly piston motion is near the high temperature low regime the top dead center, alloy does not melt, given full play to the advantage of solid lubricant, thereby lubrication and seal effect is preferably arranged.The experiment of mimic high temperature wear shows that the alleged alloy of the present invention has better adhesion property-nothing to run off; The better anti-stick-slip performance-critical load of sharply wearing and tearing improves 2～3 times; Better wear resistance energy-raising is more than 1 times; Testing of engine shows the disposable alloy particle that adds in in-line, engine cylinder is pressed with the process that increases and descend gradually subsequently, and than prior art, the cylinder drops is much slow, this shows the good airproof performance of alloy at the solid lubricant film of cylinder wall formation, and arranged long work-ing life.
2. alloy utilization ratio height.The alloy abrasive dust (particulate) that the prior art scheme is produced at first spreads in pneumatic thickener, enters cylinder through oil pipe again, and the alloy loss is big, the alloy abrasive dust (particulate) that the present invention produces directly enters oil cylinder, and not only the time is lacked instant effect, and almost not loss, the utilization ratio height.
3. widely applicable.In the prior art scheme, alloy particle mainly leans on alloy block or the alloy ball along continuous straight runs in the fuel tank to slide, roll or clash into and produce, and the present invention is the vibration generation abrasive dust (particulate) when relying on engine operation.Test shows that automobile only relies on the vibration of engine self under the condition of not travelling, and alloy abrasive dust (particulate) quantity that the present invention produces can surpass in the prior art scheme at following 1～2 times that particle number is provided of the condition of running car.Therefore, the present invention is not only applicable to motor car engine, and is applicable to hard-wired diesel motor.
4. pollution-free.The alloy of prior art scheme is leaded, and alloy of the present invention is not leaded, does not have the problem of Lead contamination.
