The utility model relates to a piston and piston ring component of an internal-combustion engine, belonging to the technical field of a reciprocating type internal-combustion engine, and being used for improving the working performance of the internal-combustion engine and prolonging the service life of the internal-combustion engine. The piston and piston ring component of the internal-combustion engine comprises a first gas ring groove and a second gas ring groove which are arranged on a piston; a first C-shaped gas ring groove and a second C-shaped gas ring groove are correspondingly arranged in the first gas ring groove and the second gas ring groove; the piston and piston ring component is characterized in that the second gas ring groove is internally provided with a second gas ring and a ring matched with the second gas ring up and down; the second gas ring and the ring matched with the second gas ring have the same structure and are provided with ring holes arranged in a staggered way; the piston is provided with an oil ring groove positioned under the second gas ring; the oil ring groove is internally provided with a C-shaped oil ring sheet and a C-shaped oil ring along the up and down direction; and ring holes of the C-shaped oil ring sheet and the C-shaped oil ring are arranged in a staggered way in the oil ring groove. By the experiment, compared with similar machine types, due to the technical scheme, the service life is prolonged by 2-3 times, the fuel oil is saved by about 5%, and the maintenance work load and the maintenance cost are reduced.
Description
Technical field
The utility model belongs to the reciprocating internal combustion engine technical field, and particularly a kind of internal combustion engine and piston-ring packing are used to improve the service behaviour of internal-combustion engine and increase the service life.
Background technique
For reciprocating internal combustion engine, no matter be four-stroke or two-stroke, piston and piston-ring packing are absolutely necessary.Piston ring is divided into compression ring and oil ring, and compression ring not only determines the sealability of cylinder, improves compression performance, prevents that inflammable mixture from sealing in crankcase, also the heat of piston head can be delivered to cylinder wall by compression ring, improves the temperature environment of pistons work.Oil ring can prevent that lubricant oil from entering combustion system, influences the combustion performance and the discharging of motor.
Generally on piston, be provided with top compression ring groove, the second road compression with oil ring groove to the skirt section, be provided with top compression ring, the second road compression ring in it accordingly with oil ring from the top.But because be subjected to the influence of combustion stroke, the motion of piston ring is often at high temperature carried out, top compression ring particularly, under High Temperature High Pressure and chemical action that combustion products produced, oil film is difficult to set up, achieve relatively difficulty of perfect lubrication, and usually be in critical lubricating status.Each road ring slip surface wear extent is different, top compression ring wear extent maximum, and the second road ring is about about half of first road, the wear extent minimum of oil ring.Because each ring is the single-piece setting, in case after the wearing and tearing, the engine combustion decreased performance, power character reduces, discharging exceeds standard, and must keep in repair as early as possible, certainly will increase maintenance cost.
The model utility content
In order to solve above-mentioned deficiency, the purpose of this utility model is to provide a kind of internal combustion engine and piston-ring packing, and this internal combustion engine and piston-ring packing can improve the sealability of cylinder, prolongs the working life of piston and piston ring, reduces maintenance.
The technical solution of the utility model is: a kind of internal combustion engine and piston-ring packing, comprise the top compression ring groove and the second road compression that are arranged on the piston, the C type top compression ring and the second road compression ring correspondence place in the described top compression ring groove and the second road compression, it is characterized in that, in the second road compression, be equipped with the second road compression ring and the second road compression ring cooperation ring up and down, the described second road compression ring cooperates ring structure identical with the second road compression ring, the collar extension dislocation of the two.
Described, the described second road compression ring and the second road compression ring cooperate collar extension dislocation 180 degree of ring.
Further, the below that is positioned at the second road compression ring on the described piston is provided with oil ring groove one, is provided with C type oil ring thin slice and C type oil ring in the described oil ring groove along the vertical direction, and the two is the collar extension dislocation in oil ring groove.
Described oil ring thin slice and oil ring collar extension dislocation 180 degree.
The beneficial effects of the utility model are:
1, owing in the second road compression, is equipped with the second road compression ring and the second road compression ring cooperation ring up and down, the collar extension dislocation of the two, so just increased the sealability of piston ring, also increased the passage of piston head simultaneously, improved combustion performance to the heat radiation of cylinder wall.Simultaneously in the second road compression, be equipped with the twice compression ring up and down, can also avoid the rugged environment of top compression ring groove, improve reliability.
2, owing to be provided with C type oil ring thin slice and C type oil ring along the vertical direction in oil ring groove, the two is the collar extension dislocation in oil ring groove, can avoid wearing machine oil as far as possible like this.
3, through test, the comparable similar type of the technical program improves life-span 2-3 doubly, and it is about 5% to save fuel oil, has reduced amount of maintenance and maintenance cost.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a partial structurtes schematic representation.
Among the figure: 1 cylinder, 2 pistons, 3 top compression rings, 4 top compression ring grooves, 5 second road compression rings, 6 second road compression rings cooperate ring, 7 second road compressions, 8 oil ring thin slices, 9 oil rings, 10 oil ring grooves.
Embodiment
As shown in Figure 1, a kind of internal combustion engine and piston-ring packing, relate to cylinder 1 and piston 2, comprise the top compression ring groove 4, the second road compression 7 and the oil ring groove 10 that are arranged on the piston, existing C type top compression ring 3 is arranged in the described top compression ring groove 4.Be equipped with the second road compression ring 5 and the second road compression ring cooperation ring 6 in the second road compression 7 up and down, the described second road compression ring cooperates ring structure identical with the second road compression ring, and the collar extension dislocation of the two is preferably collar extension dislocation 180 and spends.The second road compression ring and the second road compression ring cooperate the dislocation of ring to cooperate ring that groove is set at the second road compression ring and the second road compression ring simultaneously by on the side of the second road compression 7 locating stud being set, and the location by locating stud and groove cooperates realizes.Be provided with C type oil ring thin slice 8 and C type oil ring 9 in oil ring groove 10 along the vertical direction, the two is the collar extension dislocation in oil ring groove, preferably collar extension dislocation 180 degree.By cooperating the position structure that encircles, the location that can realize C type oil ring thin slice 8 and C type oil ring 9 equally as the second road compression ring and the second road compression ring.
The technical program not only is suitable for diesel engine, also can be suitable for petrol engine.
