Abstract
The utility model discloses a novel piston of an internal combustion engine. The novel piston comprises a piston body, a pin hole is formed in the middle of the piston body, three piston ring grooves are formed in the portion, above the pin hole, of the side wall of the piston body, the three piston ring grooves include a first gas ring groove, a second gas ring groove and an oil ring groove sequentially from top to bottom, five to twenty annular anti-expansion grooves are formed in the portion, above the first gas ring groove, of the side wall of the piston body, and an annular thermal insulation groove is formed in the portion, between the first gas ring groove and the second gas ring groove, of the side wall of the piston body. The novel piston of the internal combustion engine has the advantages that air pressure of a piston ring is reduced effectively, the temperature of the piston ring is reduced, and the service life of the piston ring is prolonged; meanwhile, horsepower of the internal combustion engine is increased, and oil consumption is reduced.
Description
Technical field:
The utility model relates to a kind of internal combustion engine component, is specifically related to a kind of Novel internal combustion engine piston.
Background technique:
Existing internal combustion engine is all designed to be Spielpassung with cylinder liner, due to the gap existing between piston and cylinder liner, thereby causes poor sealing performance, and gas leakage is serious, has consumed the power of internal-combustion engine, the life-span of finally having limited internal-combustion engine.
Model utility content:
The purpose of this utility model is to provide a kind of Novel internal combustion engine piston of effective prolongation Service Life of Piston Ring.
The utility model is implemented by following technological scheme: Novel internal combustion engine piston, it comprises piston main body, be provided with pin-and-hole at described piston main body middle part, on the described piston main body sidewall above described pin-and-hole, be provided with three piston ring grooves, three described piston ring grooves are followed successively by first gas ring groove, second gas ring groove and oil ring groove from top to bottom, are provided with 5-20 the anti-swollen groove of annular on the described piston main body sidewall above described first gas ring groove; On the described piston main body sidewall between described first gas ring groove and described second gas ring groove, be provided with an annular heat dam.
In described second gas ring groove, be provided with Combined gaseous ring, described Combined gaseous ring is made up of two main rings and a grommet, and described grommet is made up of high-abrasive material, is clipped between two described main rings, together be placed in a described piston ring groove, collar extension staggers mutually.
The external diameter of described grommet is identical with the external diameter of described main ring, and its internal diameter is greater than the internal diameter of described main ring.
Advantage of the present utility model: effectively alleviate piston ring atmospheric pressure, reduced the temperature of piston ring, extended the working life of piston ring; Increase internal-combustion engine horsepower simultaneously, reduced oil consumption.
Brief description of the drawings:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is use schematic diagram of the present utility model.
Piston main body 1, pin-and-hole 2, piston ring groove 3, first gas ring groove 4, second gas ring groove 5, oil ring groove 6, the anti-swollen groove 7 of annular, annular heat dam 8, Combined gaseous ring 9, main ring 10, grommet 11, chromium plating compression ring 12, oil ring 13.
Embodiment: as depicted in figs. 1 and 2, Novel internal combustion engine piston, it comprises piston main body 1, be provided with pin-and-hole 2 at piston main body 1 middle part, on piston main body 1 sidewall above pin-and-hole 2, be provided with 3, three piston ring grooves 3 of three piston ring grooves and be followed successively by from top to bottom first gas ring groove 4, second gas ring groove 5 and oil ring groove 6; In first gas ring groove 4, be provided with chromium plating compression ring 12; In second gas ring groove 5, be provided with Combined gaseous ring 9, Combined gaseous ring 9 is made up of two main rings 10 and a grommet 11, and grommet 11 is made up of high-abrasive material, is clipped between two main rings 10, together be placed in a piston ring groove 3, collar extension staggers mutually, has greatly improved the gas-tight property of asking of piston and cylinder liner, increases effective atmosphere in cylinder, increase temperature simultaneously, make fuel oil perfect combustion, increasing combustion engine horsepower, reduces fuel consumption; The external diameter of grommet 11 is identical with the external diameter of main ring 10, grommet 11 internal diameters are greater than the internal diameter of main ring 10, between two main rings 10 and grommet 11 threes, form an oil pocket, when piston movement, the oil scraping is stored in wherein, main ring 10 and grommet 11 are lubricated, can alleviate the wearing and tearing between ring, improve the working life of piston ring; In oil ring groove 6, be provided with oil ring 13; On piston main body 1 sidewall above first gas ring groove 4, be provided with the anti-swollen groove 7 of 5 annulars, make the piston main body 1 of first gas ring groove 4 tops carry out thermal expansion according to temperature, thereby reduce the gap between piston main body 1 and cylinder liner, reduce the atmospheric pressure to chromium plating compression ring 12, improve the working life of chromium plating compression ring 12; On piston main body 1 sidewall between first gas ring groove 4 and second gas ring groove 5, be provided with an annular heat dam 8, reduce the temperature that is delivered to Combined gaseous ring 9 from chromium plating compression ring 12, the working life of further improving Combined gaseous ring 9.
