Abstract
The utility model relates to an energy-saving and power enhancing piston of an auto engine, which is composed of a cylinder, a piston top parallel to the inner wall of the cylinder, a piston ring part, a piston skirt part, and an eclipsed form air ring positioned on the piston ring part. The existing piston uses a cone structure, and the air ring is a sectional ring. During use, the phenomena such as air storage, motor oil moving, powered lowering, and increased combustion engine oil always occur. Because the piston top of the utility model is enlarged, the relative tightness is improved and air input is enlarged. The dynamic force can be improved from 10 to 31%, and the consumption can be decreased from 5 to 15%. The directly economic benefit can be directly obtained from 2 to 2.5 ten thousands yuan.
Description
The utility model belongs to a kind of piston apparatus of motor, particularly a kind of motor car engine energy-saving force-amplifying piston apparatus.
Present domestic automobile engine piston device ubiquity cylinder barrel and the piston trim designs is unreasonable, and place, the ellipse garden in the skirt section of piston, top and piston pin boss hole is excessive with the matching gap of cylinder barrel.Therefore do not reach the distance travelled of design, occur sitting gas, oil mixed, power rapid drawdown, the increase of combustion machine oil, tail gas blackening cigarette etc. midway.Cause great loss for country and vehicle user.
The purpose of this utility model just provides a kind of low power consuming, high benefit, technology motor car engine energy-saving force-amplifying piston apparatus simple, rational in infrastructure.
Task of the present utility model is achieved in that the cone structure with the top of original piston, ring portion and skirt section changes into perpendicular to the piston bottom surface.Promptly parallel with the inner wall of cylinder of piston outside.Three road rings of piston ring portion change into intersecting folds the hermetically sealed ring of shape, changed the matching gap of original cylinder barrel and piston like this, strengthened the elastic force of compression ring, also strengthened simultaneously the sealing intensity of ring and casing wall, remedied old-fashioned seal gas ring and changed because of wearing and tearing produce opened gap, and the shortcoming of going here and there oil, sitting gas.Because piston head strengthens, and has improved relative tightness, has increased air inflow.Folded shape compression ring can not produce the phenomenon of opened gap change because of casing wall and wear of piston-rings.Compression ratio improves relatively, and power increases.Exhaust emissions purifies relatively.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Accompanying drawing is a plan view of the present utility model.
Automobile engine energy-saving force-amplifying piston apparatus mainly is made up of cylinder barrel (1), piston (2), folded shape compression ring (5), oil ring (7).
Piston (2) comprises top land (4), piston ring portion (6), piston skirt (8) and piston bottom surface (9).
Top land (4), piston ring portion (6), piston skirt (8) are perpendicular to piston bottom surface (9), and just parallel with the inwall of cylinder barrel (1), its fit clearance (3) is 0.09-0.9mm, and Optimum clearance (3) is 0.1-0.4mm. In piston ring portion (6) folded shape compression ring (5) and oil ring (7) are housed, folded shape compression ring (5) for intersect stacked, ganoid no section full sealing ring lap for vertically, divide equally, overlap.
Use the utility model can improve original machine power, reduce fuel consumption, reduce Cost of repair and maintenance.
Embodiment:
To liberate 141 lorries is example, and the cone structure that original automobile is sent out machine piston (2) changes the vertical arrangement of piston head (4), piston ring portion (6), piston skirt (8) into, promptly perpendicular to piston bottom surface (9).Matching gap (3) between piston head (4), piston ring portion (6), piston skirt (8) and the cylinder barrel (1) is 0.65mm, and compression ring adopts folded shape compression ring (5).After the installation, improve former machine power (diesel oil) 10-31%, (gasoline) 5-15% reduces fuel consumption 5-15% simultaneously.Can obtain ten thousand yuan of direct economic benefit 2-2.5.
Claims (4)
1, a kind of motor car engine energy-saving force-amplifying piston apparatus, it is made up of cylinder barrel, piston, compression ring, oil ring, it is characterized in that piston head (4), piston ring portion (6), piston skirt (8) perpendicular to piston bottom surface (9), compression ring just parallel, piston ring portion (6) with the inwall of cylinder barrel (1) be hermetically sealed folded shape compression ring (5),
2,, it is characterized in that the matching gap (3) between said piston head (4), piston ring portion (6), piston skirt (8) and cylinder barrel (1) inwall is 0.09-0.9mm according to the described motor car engine energy-saving force-amplifying of claim 1 piston apparatus.
3,, it is characterized in that the matching gap (3) between said piston head (4), piston ring portion (6), piston skirt (8) and cylinder barrel (1) inwall is 0.1-0.4mm according to claim 1,2 described motor car engine energy-saving force-amplifying piston apparatus.
4, according to the described motor car engine energy-saving force-amplifying of claim 1 piston apparatus, the lap that it is characterized in that said folded shape compression ring (5) is vertically, divides equally, overlaps.
