Abstract
The utility model discloses more reasonably single-cylinder air-cooled diesel engine piston structure of a kind of structure, comprise: cylindrical piston body, be arranged on the skirt section and the top that is arranged on cylindrical piston body upper end of cylindrical piston body lower end, both sides, middle part at cylindrical piston body are respectively arranged with piston pin hole, crown center position in described cylindrical piston body upper end is provided with firing chamber, be provided with taper projection in the inside of firing chamber, the upper end of described taper projection is provided with plane, on the top of both sides, described firing chamber, be respectively arranged with intake valve hole and exhaust valve hole, the center deviation of described firing chamber is cheated a side position to exhaust valve, on the circumference of the upper end of described cylindrical piston body, be respectively arranged with three road piston gas ring grooves with together with piston oil ring groove.Advantage is: structure is more reasonable, and airtight effect is good, and water conservancy diversion is effective, and fuel is more abundant in combustion chambers burn.
Description
Technical field
The utility model relates to a kind of single-cylinder air-cooled diesel engine, relates in particular to a kind of single-cylinder air-cooled diesel engine piston structure.
Background technique
The feature that single-cylinder air-cooled diesel engine is lightweight with it, volume is little, simple in structure, easy to maintenance, is subject to users' favor deeply.The piston structure of existing single-cylinder air-cooled diesel engine comprises: comprising: cylindrical piston body, be arranged on the skirt section and the top that is arranged on cylindrical piston body upper end of cylindrical piston body lower end, both sides, middle part at cylindrical piston body are respectively arranged with piston pin hole, crown center position in described cylindrical piston body upper end is provided with firing chamber, be provided with taper projection in the inside of firing chamber, on the top of both sides, described firing chamber, be respectively arranged with intake valve hole and exhaust valve hole, on the circumference of the upper end of described cylindrical piston body, be respectively arranged with two road piston gas ring grooves with together with piston oil ring groove.Above-mentioned single-cylinder air-cooled diesel engine piston structure, because the interior tapered projection upper end of firing chamber is that conical top is sharper, water conservancy diversion effect is bad, firing chamber is in piston middle part, unreasonable structure, and fuel combustion is insufficient, only have twice piston gas ring groove, airtight effect is bad.
Model utility content
Technical problem to be solved in the utility model is: more reasonably single-cylinder air-cooled diesel engine piston structure of a kind of structure is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: single-cylinder air-cooled diesel engine piston structure, comprise: cylindrical piston body, be arranged on the skirt section and the top that is arranged on cylindrical piston body upper end of cylindrical piston body lower end, both sides, middle part at cylindrical piston body are respectively arranged with piston pin hole, crown center position in described cylindrical piston body upper end is provided with firing chamber, be provided with taper projection in the inside of firing chamber, the upper end of described taper projection is provided with plane, on the top of both sides, described firing chamber, be respectively arranged with intake valve hole and exhaust valve hole, the center deviation of described firing chamber is cheated a side position to exhaust valve, on the circumference of the upper end of described cylindrical piston body, be respectively arranged with three road piston gas ring grooves with together with piston oil ring groove.
The utility model has the advantages that: above-mentioned single-cylinder air-cooled diesel engine piston structure, structure is more reasonable, and airtight effect is good, and water conservancy diversion is effective, and fuel is more abundant in combustion chambers burn.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model single-cylinder air-cooled diesel engine piston structure.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In figure: 1, cylindrical piston body, 2, skirt section, 3, top, 4, piston pin hole, 5, firing chamber, 6, taper projection, 7, plane, 8, intake valve hole, 9, exhaust valve hole, 10 piston gas ring grooves, 11, piston oil ring groove, 12, piston center line, 13, firing chamber center line.
Embodiment
Describe in detail particular content of the present utility model below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Fig. 2, single-cylinder air-cooled diesel engine piston structure, comprise: cylindrical piston body 1, be arranged on the skirt section 2 and the top 3 that is arranged on cylindrical piston body 1 upper end of cylindrical piston body 1 lower end, both sides, middle part at cylindrical piston body 1 are respectively arranged with piston pin hole 4, 3 neutral positions, top in described cylindrical piston body 1 upper end are provided with firing chamber 5, be provided with taper projection 6 in the inside of firing chamber 5, the upper end of described taper projection 6 is provided with plane 7, on the top 3 of 5 both sides, described firing chamber, be respectively arranged with intake valve hole 8 and exhaust valve hole 9, the center deviation of described firing chamber 5 is to exhaust valve hole 9 one side positions, on the circumference of the upper end of described cylindrical piston body 1, be respectively arranged with three road piston gas ring grooves 10 with together with piston oil ring groove 11.
Above-mentioned single-cylinder air-cooled diesel engine piston structure, due to 5 interior tapered projection 6 upper ends, firing chamber, to be arranged on plane 7 its water conservancy diversion better effects if good, firing chamber 5 center deviations are to exhaust valve hole 9 one side positions, as shown in Figure 2, taking piston center line 12 as benchmark, can clearly find out that firing chamber center line 13 is partial to exhaust valve hole 9 one side positions, structure is more reasonable, fuel combustion is more abundant, as shown in Figure 1 simultaneously, on the circumference of the upper end of described cylindrical piston body 1, be provided with three road piston gas ring grooves 10, airtight effect is better.
