Description

The energy-saving piston device

The utility model relates to a kind of piston apparatus, particularly a kind of energy-saving piston device.

The internal combustion engine device that power machines such as current automobile, internal combustion locomotive, steamer, tractor, motorcycle, air compressor use, the compression ring of piston apparatus is constantly wearing and tearing at the volley, growth along with service time, the opened gap wearing and tearing of compression ring increase to 1.0 millimeters, when the wearing and tearing of crack, limit increase to 0.5 millimeter, the performance index of internal-combustion engine are descended, increase as fuel oil, lubricating oil consumption, horsepower descends, this internal-combustion engine will collaborate, go here and there oil, use until can not continuing, thereby shortened the working life of internal-combustion engine.

The purpose of this utility model is for a kind of good seal performance being provided, increasing the service life, and saves fuel oil, lubricating oil, improves internal-combustion engine horsepower, reduces atmospheric pollution, and cost is low, the energy-saving piston device of high efficiency.

The utility model is realized by following scheme: the piston gas ring groove of internal combustion engine device is made a double pressure ring groove of putting two compression rings, on the upper and lower sidewall of this double pressure ring groove, respectively stud with the position limit pin of a limit compression ring circumferential movement, two position limit pins can phase place 180 °, the exposed length of these two position limit pins must not exceed the outside of double pressure ring groove, and this two position limit pins exposing in the double pressure ring groove highly is not higher than 1/2 of this position limit pin diameter; In the double pressure ring groove, put two grommets earlier, these two grommets are made half garden shape shape of many angles, on these two grommets and be shaped on half garden connected in star by position limit pin, half garden connected in star of these two grommets should be aimed at two position limit pins respectively, put two grommet sheets again near the periphery of grommet, two grommet sheets are made half garden shape shape, be shaped on half garden connected in star on these two grommet sheets by position limit pin, half garden connected in star on these two grommet sheets should be aimed at two position limit pins respectively, promptly played the effect that the collar extension air-flow is led in sealing double pressure ring back clearance and crack, limit, and then put two compression rings, the opening of these two compression rings is shaped on half garden v notch v, half garden v notch v of these two compression rings should be aimed at two position limit pins respectively, the width of the double pressure ring groove of this energy-saving piston device equals the thickness and the mating edge crack sum of two compression rings, the degree of depth of double pressure ring groove equals the width and the grommet of double pressure ring, the thickness of grommet sheet adds the back clearance sum and adapts, and so promptly constitutes the energy-saving piston device.The piston head of this energy-saving piston device can be that protruding top, concave crown, flat-top, combination are pushed up various piston-shaped; The shape of the piston skirt of this energy-saving piston device can be known various piston skirt shape; The oil ring that uses on the piston of this energy-saving piston device can be various structure shapes, and this energy-saving piston device can be made with various metallic material.

Owing to put grommet in the double pressure ring groove of this model utility, grommet sheet and two compression rings, even the wearing and tearing of the opened gap of compression ring increase to 2.5-3.5 millimeters, when the crack, limit increases 0.5 millimeter, can not make yet internal-combustion engine upper and lower collaborate, go here and there oil, thereby prolong the working life that makes internal-combustion engine more than 1 times, horsepower increases 8-10%, save fuel oil 10-15%, save lubricating oil 40-50%, also reduced discharge amount of exhaust gas simultaneously, thereby reduced pollution air, and internal-combustion engine is started easily, the easy startability of diesel engine is more superior.The utility model is implemented easily, and purposes is wide, and cost is low, high efficiency, and the piston apparatus of every various automobiles, tractor, motorcycle, internal combustion locomotive, steamer, air compressor etc. can adopt.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the utility model structural profile schematic representation that the 492Q petrol engine uses

Fig. 2 is the utility model grommet structural representation

Fig. 3 is the utility model grommet chip architecture schematic representation

In Fig. 1 to Fig. 3,1 be piston head, 2 for the double pressure ring groove, 3 for position limit pin, 4 for double pressure ring, 5 for grommet, 6 for the grommet sheet, 7 for oil ring groove, 8 for oil ring, 9 for piston Xiao hole, 10 for piston skirt.

Referring to figs. 1 through Fig. 3, the Piston Compression annular groove of the piston apparatus that is shaped on is made a double pressure ring groove 2 of putting two compression rings 4, on double pressure ring groove 2, respectively stud with the position limit pin 3 of a limit compression ring circumferential movement on the lower wall, the exposed length of position limit pin 3 does not exceed the outside of double pressure ring groove 2, position limit pin exposing in two compression grooves 2 highly is not higher than 1/2 of position limit pin 3 diameters, two position limit pins 3 in the double pressure ring groove 2 can phase place 180 °, put two grommets 5 in the double pressure ring groove 2 earlier, grommet 5 is made half garden shape shape of many angles, on two grommets 5 and be shaped on half garden connected in star by position limit pin 3, half garden connected in star of these two grommets 5 should be aimed at two position limit pins 3 respectively, put two grommet sheets 6 again near the periphery of grommet 5, two grommet sheets 6 are made half garden shape shape, be shaped on half garden connected in star on these two grommet sheets 6 by position limit pin 3, half garden connected in star of these two grommet sheets 6 should be aimed at two position limit pins 3 respectively, and then put two compression rings 4, the opening of these two compression rings 4 is shaped on half garden v notch v, half garden v notch v of these two compression rings 4 must be aimed at two position limit pins 3 respectively, the width of this model utility double pressure ring groove equals the thickness and the mating edge crack sum of double pressure ring, the thickness that the degree of depth of the double pressure ring groove 2 of this model utility equals the width of double pressure ring 4 and grommet 5 and grommet sheet 6 adds the back clearance sum and adapts, other structure of the piston apparatus of this internal-combustion engine is constant, promptly constitutes the energy-saving piston device.
