Abstract
An internal combustion engine cylinder piston with oil-gas rings is disclosed by the utility model. Top of the piston is provided with a gas ring groove with two or more gas rings closely connected. The gas rings are lined with reeds; skirt of the piston is provided with an oil-ring groove arranged with an oil ring inside. The oil ring is lined with a reed or steel wire. The gas rings are well sealed. When the gas rings and the oil ring are worn and torn, gap between the piston and a cylinder can be automatically regulated with excellent stability. By introducing such a utility model, wear between the piston and the cylinder is smaller, fuel is saved, and power loss is reduced; in addition, fuel can be fully burnt without black smoke and the utility model is good for environmental protection.
Description
Technical field
The utility model relates to a kind of internal-combustion engine arrangement, is specifically related to a kind of piston with novel oil gas ring that is installed in the cylinder of internal combustion engine.
Background technique
Current, on the piston in the cylinder of internal combustion engine, major part is equipped with single seal gas ring and common oil ring, owing to install, compression ring and oil ring must circumferentially have opening along it, and this just causes compression ring can't keep excellent sealing at opening, when pistons work, energy behind partially mixed gas and the mixture combustion is arranged from the loss of compression ring opening, work increases the opening of compression ring and oil ring for a long time, the wearing and tearing of compression ring and oil ring simultaneously, gap between piston and the cylinder is increased, wearing and tearing aggravate, and have increased the running resistance of piston, and the internal-combustion engine fuel consumption is increased, power descends, oil inflame is insufficient, black smoke occurs, befouling environment.
Summary of the invention
Technical problem to be solved in the utility model is: solve the following problems that the prior art piston exists: oil gas ring poor sealing performance, after compression ring and the oil ring wearing and tearing, compression ring, oil ring can not be regulated the gap of itself and cylinder automatically, and the gap between piston and the cylinder increases, the wearing and tearing aggravation, increased the running resistance of piston, the internal-combustion engine fuel consumption is increased, and power descends, and oil inflame simultaneously is insufficient, black smoke appears, befouling environment; And a kind of oil gas ring good seal performance, compression ring and the oil ring cylinder of internal combustion engine piston with novel oil gas ring of the uniform circular gap between regulating piston and the cylinder automatically is provided.
The technical solution adopted in the utility model is: piston top is processed with compression, the compression ring that two or more closely link to each other is installed in the compression, is lined with reed in the compression ring, the piston skirt is processed with oil ring groove, oil ring is installed in the oil ring groove, is lined with reed or steel wire in the oil ring.
In the technique scheme: the reed of compression ring liner is processed into has the spring sheet open circles that a plurality of arcs connect.
In the technique scheme: the reed of oil ring liner is processed into one and has spring sheet open circles or the Spring Steel Wire open circles that a plurality of arcs connect.
In the technique scheme: be processed with on the piston circumferential surface a plurality of even between the oil outlet of cloth.
The beneficial effects of the utility model are: solve the conventional art piston compression ring poor sealing performance that oils, after compression ring and the oil ring wearing and tearing simultaneously, compression ring and oil ring be the uniform circular gap between regulating piston and the cylinder automatically, wearing and tearing aggravation between piston and the cylinder, the internal-combustion engine fuel consumption increases, and power descends, and oil inflame simultaneously is insufficient, black smoke appears, problem of environment pollution caused; Oil gas ring good seal performance of the present utility model, the uniform circular gap between compression ring and automatic regulating piston of oil ring energy and the cylinder is saved the internal-combustion engine fuel consumption, and power loss is little, and oil inflame is abundant, black smoke do not occur, helps environmental protection.

Embodiment
Referring to Fig. 1 to Fig. 6, this piston structure with novel oil gas ring that is installed in the cylinder of internal combustion engine is: piston 1 is made by aluminum alloy, and piston 1 top is processed with compression, and the bottom is processed with oil ring groove, secondary compression ring 2, main compression ring 3 are installed in the compression, oil ring 4 is installed in the oil ring groove.On near the piston circumferential surface below the compression, evenly processing optimum value and be 6, the oil outlet of aperture 1.5mm.Compression ring comprises a main compression ring 3 and a secondary compression ring 2 and a compression ring spring 5 in the piston, these two compression rings and compression ring spring are along an opening is circumferentially all arranged, oil ring 4 comprises the main oil ring and the oil ring spring 6 that evenly are processed with a plurality of windows on circumferential side surface, main oil ring and oil ring spring are along an opening is circumferentially all arranged, compression ring spring 5 is a spring sheet, and a spring sheet open circles with the smooth connection of a plurality of arcs is processed in coiling.The oil ring spring be spring sheet or Spring Steel Wire too coiling be processed into a spring sheet open circles or a Spring Steel Wire open circles with the smooth connection of a plurality of arcs.Secondary compression ring is stacked on the main compression ring, and the opening of two compression rings is inserted in the compression along the angle that circumferentially staggers mutually, and main oil ring is inserted in the oil ring groove.The oil ring spring is that the spring sheet or the Spring Steel Wire of the smooth connection of a plurality of arcs pushes in the interior a plurality of windows of main oil ring, fix, this piston that has novel oil gas ring in the cylinder of internal combustion engine that is installed in, compression ring and cylinder form good sealing, after compression ring and the oil ring wearing and tearing simultaneously, compression ring and oil ring guarantee the stability of piston motion by the spring of packing into the separately uniform circular gap between regulating piston and the cylinder automatically, and the wearing and tearing between piston and the cylinder reduce.And the formation of carbon deposit in the loss of energy and the piston groove when reed of the compression ring inboard of packing into can also be controlled because of the increase of ring wearing clearance.
The utility model does not have wandering away of mixed gas and acting back energy basically; this two compression rings that stack together can prevent that again machine oil from infiltrating burning; oil ring is placed the piston skirt; and it is the same with compression ring; liner suitable thickness reed; and make piston not with the hinged friction of cylinder, thereby reach the purpose of saving fuel oil, increasing power, also help environmental protection.
