Abstract
The utility model relates to an internal combustion engine piston, and each groove in the piston ring groove is embedded with two piston rings whose ring openings are opposite. The utility model has reasonable structure, easy manufacture and long service life.
Description
Affiliated technical field
The utility model relates to a kind of improvement of internal combustion engine, particularly with groove dicyclic internal combustion engine.
Background technique
At present, traditional internal combustion engine structure all is a groove one ring, in use, because phase mutual friction between compression ring, oil ring and the cylinder liner, the outer rim of compression ring, oil ring and the inner edge of cylinder liner produce wearing and tearing, cause collar extension to increase, produce cylinder interior and divide the combustion gas body phenomenon of bleeding, cause the underpower of machinery and the waste of the energy, the tail gas of Pai Chuing also can strengthen the pollution to surrounding environment simultaneously, and the big needs of relevant parts wear are changed in advance.
Summary of the invention
In order to overcome the existing structural deficiency of internal combustion engine, the utility model provides a kind of internal combustion engine, simple in structure, easy manufacturing, the whole service life of prolongation internal-combustion engine.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of internal combustion engine, comprise piston ring groove, piston ring, oil hole, piston rod pin-and-hole and interior jump ring groove, its piston ring groove width is the width of double piston ring, and every groove is embedded in two opposing piston rings of collar extension.
Embed two opposing identical piston rings of collar extension in every compression; Two piston rings that the collar extension that embeds in the oil ring groove is opposing, wherein one is thin slice shape.
The beneficial effects of the utility model are, and are simple in structure, improve the whole service life of internal-combustion engine, energy-conservation, help environmental protection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model example structure schematic representation.
Among the figure, 1, internal combustion engine; 2, compression; 3, piston ring; 4, piston ring; 5, oil hole; 6, oil ring groove; 7, piston ring; 8, thin slice piston ring; 9, interior jump ring groove; 10, piston pin hole.
Embodiment
Piston 1 is provided with two circle compressions 2, two circle oil ring grooves 6, piston pin hole 10, interior jump ring groove 9 and oil hole 5, compression 2 is embedded in collar extension opposing piston ring 3 and piston ring 4, oil ring groove 6 is embedded in piston ring 7 and the opposing thin slice piston ring 8 of collar extension with it, oilhole 5 is located in the oil ring groove 6, and interior jump ring groove 9 connects with piston pin hole.
