Description

High efficient piston for internal-combustion engine

The utility model relates to the internal-combustion engine seal arrangement, particularly a kind of high-effect internal combustion engine device.

Current automobile, train, steamer, aircraft, the piston apparatus of the internal-combustion engine that power machines such as air compressor use (or claiming motor) all is single compression ring slot type structure, only put a compression ring in the single compression annular groove, growth along with service time, compression ring is constantly wearing and tearing at the volley, the technical order of internal-combustion engine is descended, as fuel oil, the lubricating oil consumption increases, horsepower descends, discharge amount of exhaust gas increases, atmospheric pollution increases, compression ring is because wearing and tearing, opened gap increases to more than 2 millimeters, this internal-combustion engine will be gone here and there oil, collaborate increase up and down and make internal-combustion engine can not continue to use, thereby shortened the working life of internal-combustion engine.

The purpose of this utility model be for a kind of good seal performance, long service life, saving fuel oil, lubricating oil, raising internal-combustion engine horsepower be provided, reduce atmospheric pollution, cost is low, the high-effect internal combustion engine device of high efficiency.

The utility model is realized by following scheme.Being shaped on piston head, (list compresses annular groove to above oil ring groove together, oil ring groove is commonly referred to piston ring groove), piston pin boss, the piston ring groove of the piston apparatus of the internal-combustion engine of piston skirt structure is made one or two double pressure ring groove, in the double pressure ring groove, put grommet earlier, put two compression rings near the grommet periphery, the gap, limit of two compression rings is constant, the width of double pressure ring groove equals the thickness and the mating edge crack sum of two compression rings, the thickness and the back clearance sum of the width grommet of the degree of depth of double pressure ring groove and compression ring adapt, in oil ring groove, put by one and serve as a contrast spring and serve as a contrast spring each two combined oil ring that scraping blade constitutes up and down, the opening of two adjacent scraping blades can phase place 180 °, promptly constitutes high-effect internal combustion engine device; In addition, in the double pressure ring groove of this piston apparatus, be shaped on pin-and-hole on the top and bottom sidewall, and at the position limit pin of the restricted compression ring circumferential movement of its pin-and-hole internal fixation, position limit pin exposes the height of the bared end in the double pressure ring groove must be less than the degree of depth of double pressure ring groove, two position limit pins in the double pressure ring groove on the top and bottom sidewall can phase place 180 °, the opening of two compression rings putting in the double pressure ring groove also can phase place 180 °, the opening of the compression ring in the double pressure ring groove is shaped on half garden v notch v, half garden v notch v of compression ring opening must be aimed at the bared end of position limit pin, so also can constitute the internal combustion engine device; The grommet of this piston apparatus can be made the polygonal shape of certain angle, on grommet and be shaped on half garden connected in star by position limit pin; The shape of the piston head of this piston apparatus can be that various piston head shapes are pushed up on protruding top, concave crown, flat-top, combination; The shape of the piston skirt of this piston apparatus can be known various piston skirt shape; This piston apparatus can be made with various metallic material.

Owing to put grommet and two compression rings in the double pressure ring groove of this model utility, put combined oil ring in the oil ring groove, the opened gap of compression ring had both made wearing and tearing increase to 3～4 millimeters, internal-combustion engine still can not collaborated, go here and there oily up and down, thereby prolong 70～80% the working life that makes internal-combustion engine, and horsepower increases by 8～10%; The fuel oil per 100 km can be saved 3～5 liters, and per five the kilometer strokes of lubricating oil can be saved more than 10 kilograms, have also reduced discharge amount of exhaust gas simultaneously, thereby have reduced the pollution to air, and internal-combustion engine is started easily, and the easy startability of diesel engine is more superior; The utility model is implemented easily, purposes is wide, cost is low, high efficiency, the power machine of the various piston apparatus of every use internal-combustion engine is no matter the piston apparatus of automobile, motorcycle, train, steamer, aircraft, tractor, air compressor etc. can adopt the utility model.

Below in conjunction with drawings and Examples the utility model is described in further detail:
