Description
Technical field
The invention belongs to oil duct cooling technology fields, and in particular to a kind of linkage using the cooling piston of oil duct.
Background technique
For engine, there is very important influence to engine performance in the temperature of expiratory phase gas in the jar,
The gas in the jar temperature the low more is conducive to be promoted volumetric efficiency, reduces ignition temperature and inhibits the generation to discharge pollutants, meanwhile,
It is also beneficial to the promotion of engine reliability, therefore, it is necessary to cooling appropriate is carried out to the gas in cylinder, and piston temperature is to cylinder
The cooling of interior gas and the reliability of piston itself have important influence, it is therefore necessary to reduce piston temperature, reinforce to piston
It is cooling.Currently, most of engine cools down piston combustion bowl periphery using the method for cooling spray hook injection machine oil.
As the utility model patent of publication number CN207033717U discloses in a kind of high pressure reciprocating pump with oil duct
Connecting rod, including gonnecting rod body, connecting rod cap, connecting rod upper bearing shell, connecting rod lower bearing shell and lining of connecting rod small end；Gonnecting rod body by connecting rod shank and
Small end of connecting rod, major part are constituted, and are formed with center oil transportation hole on connecting rod shank；Connecting rod cap is fixed on big end；Axis on connecting rod
It watt is mounted on big end inner peripheral surface, middle part is formed with the top bearing shell oilhole being connected with center oil transportation hole, inner peripheral surface
It is formed with the first Circumferential oil groove, the first Circumferential oil groove bottom surface is formed with the first radial oil groove；Connecting rod lower bearing shell and connecting rod upper bearing shell
Structure is essentially identical.
As can be seen that mainly considering connecting rod lubrication and cooling in the design of connecting rod oil line in the prior art, cannot achieve
Cooling to piston base.
Summary of the invention

103；Cooling oil duct 105 is also provided in the small end of connecting rod 101, the cooling oil duct 105 is equipped with oil inlet 104 and jet
106, cooling oil enters from oil inlet 104, until jet 106 sprays, for cooling down the bottom structure 201 of piston 200, to drop
The surface temperature of low 200 bottom structure 201 of piston reinforces the cooling to piston 200, increases gas in the jar heat dissipation capacity, reduces
Gas in the jar temperature.
In one embodiment, the outer surface of the bushing 102 is additionally provided with bushing oil duct (not shown).
In one embodiment, the cooling oil duct 105 is arranged in the periphery of bushing oil duct, the cooling oil duct 105 with
Bushing oil duct is mutually indepedent.
In one embodiment, the jet 106 is arranged in the top of small end of connecting rod 101, and cooling effect is more.
It is thus described several aspects of at least one embodiment of this invention, it will be understood that those skilled in the art
For be easy to carry out various changes, modification and improvement.This changes, modifications and improvement are intended in the spirit and scope of the present invention
It is interior.
