Sound, improve cylinder sleeve use reliability and life-span.
A kind of single cylinder horizontal diesel engine wet cylinder liner, the top of cylinder sleeve are provided with boss prominent laterally, and the end at top
Face is higher than body plane, is provided with the middle part of the cylinder sleeve and compresses positive stop lug boss, with top land position phase during body piston lower dead center
It is corresponding, spron is provided with below the compression positive stop lug boss side, the bottom of the cylinder sleeve is provided with two annular grooves, the ring
Sealing ring is installed in shape groove.
Preferably, the boss is annular fire prevention boss.
Preferably, the spron is dual-trench type structure, and the trench structure of two grooves is circular arc.
Preferably, two groove width differences of the spron.
Preferably, the compression positive stop lug boss is along the circumferential direction set using interruption, and discontinuities open up circular arc heating power
Groove.
Beneficial effect：The utility model provides a kind of single cylinder horizontal diesel engine wet cylinder liner, by the side end to end of existing cylinder sleeve
Formula is changed to head, middle and end three-stage positioning, and support positioning will be set in the middle part of cylinder sleeve so that cylinder sleeve is not susceptible to stress at work
Deformation, the thickness of cylinder sleeve can be effectively reduced, save material, alleviated vibration during cylinder sleeve work, reduce noise, subtract simultaneously
The risk of cavitation pitting is lacked；Stress dispersion slot is devised in midfoot support point, heating power groove has been opened up, has solved stress concentration and material
Side effect caused by accumulation, the cooling effect in the middle part of cylinder sleeve is ensure that, significantly improve wet cylinder liner functional reliability and use
Life-span.

Embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the application, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, it should all belong to the application protection
Scope.
A kind of single cylinder horizontal diesel engine wet cylinder liner, the top of cylinder sleeve 1 are provided with boss 4 prominent laterally, and top
End face 5 is higher than body plane, and the middle part of cylinder sleeve 1, which is provided with, compresses positive stop lug boss 6-1, with top land during body piston lower dead center
Position is corresponding, and spron 6-2 is provided with below the compression positive stop lug boss 6-1 sides, and the bottom of the cylinder sleeve 1 is provided with two
Annular groove 7, sealing ring is installed in the annular groove 7.
Preferably, the boss 4 is annular fire prevention boss.
Preferably, the spron 6-2 is dual-trench type structure, and the trench structure of two grooves is circular arc.
Preferably, two groove width differences of the spron 6-2.
Preferably, the compression positive stop lug boss 6-1 is along the circumferential direction set using interruption, and discontinuities open up circular arc heat
Power groove.
Design principle of the present utility model is as follows：
Position cylinder sleeve structure installation diagram as shown in fig. 1, cylinder sleeve 1 push up (left side) end and are provided with annular fire prevention boss 4 prominent laterally,
Obstruct erosion of the high-temperature fuel gas to head gasket 3.The end face 5 on top is slightly higher than 0.2-0.3mm than the plane of body 2, it is ensured that head gasket 3
