Description
Technical field:
What the present invention relates to is a kind of piston of internal-combustion engine.Particularly relate to a kind of piston that improves the internal-combustion engine output power.
Background technique:
Piston is internal-combustion engine " heart ", bears the mechanical load and the heat load of alternation, is one of worst key components and parts of operating conditions in the internal-combustion engine.The function of piston is to bear gas pressure, and passes to connecting rod by wrist pin and order about crankshaft rotating.Piston is worked under the condition of high temperature, high pressure, high speed, and therefore, it is serious to be heated, and owing to feature radiating condition intrinsic on the structure is very poor again, piston is worked under this harsh conditions, can produce distortion and accelerated wear test, also can produce additional load and thermal stress.So must take effective measures with the wear resistance that guarantees piston, thermal balance and guidance quality and good sealing function stably,, reduce oil consumption, noise and discharging to reduce the frictional work loss of internal-combustion engine.
Although piston is an important content of internal-combustion engine development in science and technology, intrinsic feature on its structure makes that the cylinder friction loss between casing wall and the piston skirt is not effectively improved.The piston skirt contacts with cylinder between the casing wall, if area little can not guarantee the stability of moving, if area big friction loss big.The skirt section area design of piston has been the special result who optimizes at present.But because the slit is minimum between casing wall and the piston skirt, piston is in high-speed motion, and lubricant oil can not form good oil film in the piston skirt be the major reason that produces piston distortion and accelerated wear test, and has had a strong impact on the power output of internal-combustion engine.
Chinese patent publication number CN 2365410Y, in open day on February 23rd, 2000, this application case discloses a kind of piston of low friction type, and this piston has convex portion on the surface of piston skirt, to reduce piston skirt and casing wall area of contact, realizes the purpose of low friction.Its deficiency is that the piston skirt area is little, can not guarantee the stability of piston motion, has increased the vibrations and the noise of motor.Piston is in high-speed motion in addition, and it is the major reason that can't reduce frictional force, heat power consumption that lubricant oil can not effectively arrive the piston skirt.So, have room for improvement.
Summary of the invention:
The present invention has overcome deficiency of the prior art, and has improved the internal-combustion engine output power significantly.
Structure of the present invention has guaranteed constantly to supply with, collect and store in the piston skirt lubricant oil, storage and cloth have applied the lubricant oil of capacity between piston skirt and casing wall, completely cut off the Metal Contact between piston skirt and the casing wall, reduced frictional force, heat power consumption between piston skirt and the casing wall.Thereby increased the power output of internal-combustion engine, reduced fuel consumption, noise and the discharging of internal-combustion engine.Reached the double benefit of fuel-economizing and environmental protection.
In order to achieve the above object,
The invention provides a kind of raising the piston of internal-combustion engine output power be provided,
This piston comprises: piston skirt, piston skirt wall, piston ring.
Form several through holes in the piston skirt, form a plurality of blind holes in the piston skirt, form many grooves in the piston skirt.The piston skirt through hole is arranged on the piston skirt, and the piston skirt blind hole is arranged on the piston skirt, and the piston skirt groove is arranged on the piston skirt.The piston skirt through hole provides supplying lubricating oil, and the piston skirt blind hole provides storage lubricant oil, and the piston skirt groove provides storage lubricant oil and guarantees the free-flow of lubricant oil in blind hole.
The invention provides a kind of piston that improves the internal-combustion engine output power,
When the piston of internal-combustion engine during along the axial direction high-speed motion, piston is subjected to the thermal expansion distortion, makes to form best design gaps between piston skirt and the casing wall, reaches optimum condition lubricated and the stable guiding of piston.The lubricant oil of internal-combustion engine constantly flow to the piston skirt by the piston skirt through hole and be stored in the piston skirt blind hole and the piston skirt groove in, make the lubricant oil between piston skirt and casing wall form the fluid lubrication oil film, otherwise the lubricant oil of piston skirt groove and piston skirt blind hole also constantly soaks into diffusion to all around, forms sufficient good lubricating oil film all the time.Reduce frictional force, heat power consumption between piston skirt and the casing wall, the power output of increasing combustion engine reduces fuel consumption, noise and the discharging of internal-combustion engine.Reach the purpose of fuel-economizing and environmental protection.
The invention provides a kind of piston that improves the internal-combustion engine output power,
During engine shutdown, piston is 0 o'clock in the motion of axial direction, shrinks the lubricant oil of gathering in the blind hole of the effect lower piston skirt section of oil film tension force abrim.When internal combustion engine start next time, owing to have lubricant oil between piston skirt and the casing wall, stopped directly to contact between piston skirt and the casing wall, greatly reduced the friction factor between piston skirt and the casing wall thus.Thereby reach fuel-economizing and environmental protection function.
The invention provides a kind of piston that improves the internal-combustion engine output power,
The formation of piston skirt through hole normally with circle poroid also can be the pore size distribution of other shapes in the piston skirt, the formation of piston skirt through hole runs through the piston skirt wall.The shape of through hole, big or small shape, big or small variant according to internal combustion engine.This formation of piston skirt through hole has guaranteed that lubricant oil can see through the piston skirt wall and drain into the surface, piston skirt.
The invention provides a kind of piston that improves the internal-combustion engine output power,
The formation of piston skirt groove normally is depressed in surface, piston skirt concavity grooves long strip or other shapes, normally a part is pressed on the blind hole of piston skirt, all the other somes are distributed on the piston skirt in the distribution of piston skirt groove, link to each other with the part blind hole, the degree of depth of groove is shallower than blind hole.The formation of above-mentioned piston skirt groove is relevant in the formation of piston skirt with blind hole, and groove can in axial direction link to each other with blind hole, and the position of groove can on the left and right both sides of blind hole.Groove also can link to each other with blind hole by along continuous straight runs, and the position of groove can the upper and lower of non through hole.The effect of groove is to guarantee that lubricant oil can flow in blind hole, and has guaranteed that lubricant oil can effectively be stored in the surface, piston skirt.
The invention provides a kind of piston that improves the internal-combustion engine output power,
The piston skirt blind hole is not run through the piston skirt wall.The irregular piston skirt that is distributed in of piston skirt blind hole.The blind hole that is distributed in the piston skirt is different deep mixed according to the internal combustion engine size.This formation of piston skirt blind hole has reduced the useful area of internal combustion engine cylinders and Contact of Piston Skirt, can farthest reduce the friction area of cylinder body and piston skirt.Lubricant oil can effectively be stored in the blind hole simultaneously, can free-flow by piston skirt groove lubricant oil, guaranteed the lubricant film between piston skirt and casing wall, Metal Contact with between isolated casing wall and the piston skirt reduces frictional force, heat power consumption between casing wall and the piston skirt.Thereby increased the power output of internal-combustion engine, reduced fuel consumption, noise and the discharging of internal-combustion engine.Fuel-economizing and environmental benefit are very remarkable.
