Abstract
The utility model relates to a piston for IC engine. The utility model is composed of a main body which is provided with an air ring groove and an oil ring groove, an air ring which is arranged in the air ring groove, and an oil ring which is arranged in the oil ring groove. The utility model is characterized in that the number of the air ring groove is one, the air ring groove is provided with two to four air rings whose opening ends are non-overlapping. The utility model has the advantages that the structure is simple, the sealing effect is good, and the service life can effectively be extended.
Description
The utility model relates to a kind of piston of internal-combustion piston engine, is applicable to the piston that improves internal-combustion piston engines such as petrol engine, diesel engine in the prior art.
In the prior art, the piston of internal-combustion engine general main by the main body that one group of compression and oil ring groove are arranged, place the oil ring of oil ring groove and the compositions such as compression ring that place each compression respectively; Since in each compression respectively amount a compression ring is arranged, certain intervals is arranged each other, each compression ring all has an opening end, so sealability is relatively poor, particularly use a period of time after, gas leak phenomenon is more serious, makes that combustion force weakens, oil consumption is higher, working life is shorter.
The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art, by a plurality of compression rings that opening end does not overlap arrangement are set in a compression, thereby provide a kind of can effectively improve sealability internal combustion engine.
Content of the present utility model is: a kind of internal combustion engine, by the main body that compression and oil ring groove are arranged, place the compression ring of compression, and place the oil ring of oil ring groove to form, its feature part is: the quantity of described compression (2) is 1, the not compression ring of overlapping setting (4) of 2-4 opening end (6) is arranged, to improve sealability in this compression (2).
In the described 2-4 of the utility model content compression ring (4), the opening end (6) of adjacent compression ring in twos (4) lays respectively at the two ends of the same radial line of compression (2), makes overlapping 2-4 compression ring constitute an approximate annulus integral body, in case leak-stopping gas strengthens sealability.
Compared with prior art, the utility model is owing to be provided with a plurality of compression rings overlapping and that opening end does not overlap in employing one compression, simple in structure, sealability obviously improves in the use, the no fuel phenomenon that leaks outside, and combustion force strengthens, the power that produces is big, can improve 3 times of effect and working lifes, the user cuts down expenses more than 20%, and is of many uses.
Accompanying drawing is the utility model embodiment master TV structure schematic representation.
Among the figure: 1-main body, 2-compression, 3-oil ring groove, 4-compression ring, 5-oil ring, 6-opening end.
An embodiment not of the present utility model below.
Referring to accompanying drawing.A kind of internal combustion engine, by the main body 1 that a compression 2 and oil ring groove 3 are arranged, place the oil ring 5 of oil ring groove 3, and place 2 compression rings 4 of compression 2 to form, the opening end 6 of 2 compression rings 4 lays respectively at the two ends of compression 2 same radial lines, and these 2 compression rings arranged side by side 4 constitute an approximate annulus.
This piston is not used in internal-combustion engines such as 110 types, 100 types, 95 types, 90 types, 70 types, 75 types, 65 types, 60 types, and good using effect is all arranged.
Claims (2)
1, a kind of internal combustion engine, by the main body that compression and oil ring groove are arranged, place the compression ring of compression, and place the oil ring of oil ring groove to form, it is characterized in that: the quantity of described compression (2) is 1, and the not compression ring of overlapping setting (4) of 2-4 opening end (6) is arranged in this compression (2).
2, by the described internal combustion engine of claim 1, it is characterized in that: in the described 2-4 compression ring (4), the opening end (6) of adjacent compression ring in twos (4) lays respectively at the two ends of the same radial line of compression (2).
