Abstract
The utility model relates to a piston with single slot and double air-ring structure. The utility model is characterized in that two air ring are arranged in an air ring groove; the two air rings cling together, which is equivalent to the astomatous installation; the mouths of the two air ring are mutually staggered, and a staggered optimum angle is 90 to 180 deg. The utility model has the advantages of good tightness, no air leakage, complete combustion and little pollution; the utility model saves oil material 10 % to 15 %, and prolongs the service life more than two times.
Description
The utility model belongs to a kind of piston of single groove double gas ring structure, and it can be widely used in the various internal-combustion engines.
Before the utility model is made, existing internal-combustion engine comprises that the piston of gasoline internal combustion and diesel engine nearly all is single groove list compression ring structure, promptly in a compression compression ring is installed, normally petrol engine has two compressions that two compression rings are installed respectively, diesel engine has three compressions that three compression rings are installed respectively, interval between each compression ring is about about 4mm, the shortcoming of this conventional construction is: because piston ring frequently motion in cylinder, cylinder wall and compression ring are worn, cause the compression ring mouth to open, cause sealing bad, gas leakage easily, it is insufficient to burn, the waste oil plant, and working life is short.
The purpose of this utility model provides a kind of good airproof performance, and is air tight, saves oil plant, the piston of single groove double gas ring structure of long service life.
The utility model is the improvement to single groove list compression ring piston of existing internal-combustion engine, its improvement is that two compression rings are housed in a compression, and two compression rings abut against together, is equivalent to not have a mouthful installation, two compression ring mouths stagger mutually, and the best angle that staggers is 90～180 °.
The utility model with existing single its advantage of groove list compression ring piston comparison is:
1. good airproof performance is air tight;
2. save oil plant 10～15%;
3. reduce wear, prolong working life more than one times;
4. sufficient combustion reduces atmospheric pollution;
5. can improve engine power about 15%.
Description of drawings:
Accompanying drawing is the piston schematic representation of single groove double gas ring structure.
Embodiment:
A kind of piston of single groove double gas ring structure, it is characterized in that: 2 two compression rings of compression ring 1 and compression ring are installed in a compression, these two compression rings abut against together, and compression ring 1 staggers mutually with two compression ring mouths 7 of compression ring 2, and the best angle that staggers is 90～180 °.The 3rd, oil ring groove; Piston 4 is installed in the cylinder barrel 6, and piston pin hole 5 is connected with bent axle by the bearing pin connecting rod, gives bent axle with power delivery.
