Abstract
The utility model relates to a motorcycle engine piston. An oil ring groove with 3-4 oil returning holes machined thereon is formed on the piston; several oil returning grooves are formed in the oil ring groove perpendicularly to the direction of piston pin. The number and dimension of the oil returning grooves are defined according to the actual service condition. The utility model avoids the oil ring lock caused by machine oil over thick by adding the above mentioned oil returning grooves, avoids piston ring block and machine oil combustion caused by the over high temperature of the engine, prevent the high temperature heat deformation of the piston, accordingly, reduces the engine noise, improve the dynamic performance, and prolonged the service life of the engine.
Description
Technical field
The utility model belongs to the motorcycle engine technology, is specifically related to the piston structure of motor.
Background technique
At present, the motorcycle gasoline engine piston only in oil ring groove processing 3-4 spill port just can satisfy usage requirement.But if in the Environmental Conditions of many dirt, particularly use on air-cooled engine for motorcycle, if when the filtering effect of empty filter temperature relatively poor and motor is higher, there is the not smooth phenomenon of oil return in existing spill port, directly cause phenomenons such as the super in early days mill of oil ring locking or piston ring, piston distortion or top be breakdown, and then cause engine power deficiency, noise to increase and problems such as burn oil.
Summary of the invention
The purpose of this utility model is to provide a kind of motorcycle engine piston that improves structure at the deficiency of prior art existence, and guaranteeing has enough machine oil to carry out sufficient lubrication on the piston, thus the protection piston, and the life-span and the power of assurance motor reduce noise.
The technical solution adopted in the utility model is as follows:
A kind of motorcycle engine piston has oil ring groove on piston, be processed with 3-4 spill port in the groove, and the improvement of this structure is in oil ring groove, processes several oil-return grooves perpendicular to the wrist pin direction.According to the actual service conditions of motor, this oil-return groove can be the groove of two wide 0.8-1mm, long 20-50mm, also can be the groove of four wide 0.8-1mm, long 5-10mm.
By increasing above-mentioned oil-return groove, make piston have sufficient machine oil to be lubricated, be under the dirty environment for motor and use or empty filter effect when bad, can avoid causing the oil ring locking because of machine oil is feeding-up, avoid engine temperature too high and cause piston ring locking and burn oil phenomenon simultaneously, but also can effectively prevent piston, thereby reduce engine noise because of high temperature thermal deformation, improve the power character of motor, effectively prolong the working life of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment,
Referring to Fig. 1, this motorcycle engine piston has the basic structure of pot type piston, as oil ring groove 3 is arranged on piston, is processed with 3-4 spill port 2 in the groove.This architecture advances is to process the oil-return groove 1 of two long 20-50mm of wide 0.8-1mm or four long 5-10mm of wide 0.8-1mm in oil ring groove 3 perpendicular to the wrist pin direction.
Below be under the dirty environment service condition, 20000Km road test result:
1, pot type piston: piston ring locking and serious burn oil phenomenon when 37729Km, occur.
2, piston of the present utility model: anomaly do not occur, the engine power decay is less.
Claims (3)
1, a kind of motorcycle engine piston has oil ring groove on piston, be processed with 3-4 spill port in the groove, it is characterized in that: in oil ring groove, be processed with oil-return groove perpendicular to the wrist pin direction.
2, piston according to claim 1 is characterized in that: described oil-return groove is arranged is the groove of two wide 0.8-1mm, long 20-50mm.
3, piston according to claim 1 is characterized in that: described oil-return groove is arranged is the groove of four wide 0.8-1mm, long 5-10mm.
