Description
Technical field
The utility model belongs to automobile manufacturing field, the Novel cylinder body structure of specifically a kind of integrated back oil seal seat, its
It is primarily adapted for use in 1.5L engines with supercharger.
Background technology
At present in the machinery industries such as automobile making, internal combustion engine, engine with supercharger is in order to strengthen piston cooling, on cylinder body
It is commonplace that piston cooling nozzle progress Oil injection cooling piston is installed；But the piston cooling nozzle installation site on current cylinder body exists
Near cylinder sleeve, and its structure is larger, causes the movement parts space lengths such as piston cooling nozzle and piston, connecting rod, bent axle smaller, knot
Structure difficult arrangement.
Utility model content
The purpose of this utility model is to provide a kind of Novel cylinder body structure of integrated back oil seal seat, fundamentally solves
Problem is stated, it has the advantages that simple and compact for structure, low cost, easy to use.
To achieve the above object, the utility model provides following technical scheme：The Novel cylinder body of the integrated back oil seal seat
If structure includes cylinder sleeve, the dry sump set along the equidistant array of cylinder sleeve length direction, it is characterized in that：Set in the oil groove
There is oil duct, mounting hole is provided with oil duct, nozzle is provided with mounting hole；Nozzle is provided with oil-feed including the spacing bottom in mounting hole
T-shaped nozzle carrier, the piston by spring retainer in nozzle carrier in hole, piston base are engaged with fuel feed hole, and piston sidepiece is set
There is oil guide groove, pad is provided between piston and spring.
The beneficial effects of the utility model：Meet oil sealing sealing function, cylinder body Structural strength calls under the premise of, in cylinder
Body flywheel end designs oil sealing mounting structure and replaces back oil seal seat support oil sealing, so as to simplify engine structure arrangement, save sky
Between, reduce cost.
