Embodiment
Below in conjunction with specific embodiment, a kind of supercharged engine piston cooling nozzle of the present utility model is further described.
As Figure 1-4, a kind of supercharged engine piston cooling nozzle, comprise nozzle mounting portion and nozzle body 1, described nozzle mounting portion is fixed by the mounting hole on engine cylinder-body and described engine cylinder-body, the bottom of described nozzle mounting portion is provided with the connecting head 4 be connected with main oil gallery, described nozzle body 1 one end is by described connecting head 4 and described main oil gallery UNICOM, described nozzle body 1 the other end is bent upwards and stretches in motor cylinder barrel 10, it is spray angle 9 that the central axis of described mounting hole and described nozzle body 1 stretch to angle between the end in described motor cylinder barrel 10, described spray angle 9 is acute angle.Like this, fixing by nozzle mounting portion and mounting hole, piston cooling nozzle is made to be fixed on engine cylinder-body, and nozzle body 1 one end is by connecting head 4 and main oil gallery UNICOM, the fluid in main oil gallery can be made to enter in nozzle body 1 through connecting head 4, the other end due to nozzle body 1 stretches in motor cylinder barrel 10, and the cooling oil ejected by nozzle body 1 can be made to be injected in the cylinder barrel of motor, and cools the piston only 13 in motor cylinder barrel 10.Because spray angle 9 is acute angle, the cooling liquid ejected is when piston only 13 moves upward to extreme higher position, upper target practice impact point 11 is casing wall (as shown in Figure 3), cooling liquid and then flow downward under gravity, thus cool whole cylinder barrel, the more effective to-and-fro motion to piston only 13 is lowered the temperature and cools, and also plays good lubrication to the motion of piston only 13 simultaneously; And the cooling liquid ejected is when piston only 13 moves downward extreme lower position, lower target practice impact point 12 is piston only 13 position (as shown in Figure 4), like this, directly piston only 13 is cooled, and when piston only 13 moves upward time, target practice impact point leaves piston only 13 and shifts to casing wall, avoid and only in bottom, piston only 13 directly cooled in prior art and cause piston only 13 to vibrate irregularity problem, it also avoid piston only 13 bottom coohng flow quantity comparatively large, motor power consumption increases and power loss problem.Because the to-and-fro motion of cooling liquid to piston only 13 serves cooling and lubrication, and then reduce the noise of piston only 13 motion and uneven compliance.
See accompanying drawing 1-4, a kind of supercharged engine piston cooling nozzle of the present utility model on the basis of technique scheme, Ke Yishi: described spray angle 9 is the unspecified angle between 40 °-70 °.Like this, spray angle 9 between 40 °-70 °, can be more effectively, make the cooling liquid ejected when piston only 13 moves upward to extreme higher position, upper target practice impact point 11 is casing wall (as shown in Figure 3), cooling liquid and then flow downward under gravity, thus cools whole cylinder barrel, the more effective to-and-fro motion to piston only 13 is lowered the temperature and cools, and also plays good lubrication to the motion of piston only 13 simultaneously, and the cooling liquid ejected is when piston only 13 moves downward extreme lower position, lower target practice impact point 12 is piston only 13 position (as shown in Figure 4), like this, directly piston only 13 is cooled, and when piston only 13 moves upward time, target practice impact point leaves piston only 13 and shifts to casing wall, avoid and only in bottom, piston only 13 directly cooled in prior art and cause the vibration of piston only 13, noise and irregularity problem, it also avoid piston only 13 bottom coohng flow quantity larger, motor power consumption increases and power loss problem.Because the to-and-fro motion of cooling liquid to piston only 13 serves cooling and lubrication, and then reduce noise that piston only 13 moves, vibration and uneven compliance.Preferred technological scheme can be further: described nozzle mounting portion comprises plat part 2 and cylindrical portion 3, described cylindrical portion 3 is fixed on described plat part 2 top, described cylindrical portion 3 is fixed with described mounting hole grafting, described connecting head 4 is fixed on the bottom of described plat part 2, and end face and the described engine cylinder-body of described plat part 2 fit tightly fixing.Like this, complete fixing, and the end face of plat part 2 and described engine cylinder-body fit tightly fixing by cylindrical portion 3 and mounting hole grafting, it is fixing more firm to make further, avoids when spraying cooling oil, the loosening problem caused due to vibrations.
See accompanying drawing 1-4, a kind of supercharged engine piston cooling nozzle of the present utility model is on the basis of technique scheme, can be: described plat part 2 is provided with the mistake proofing portion 5 of protruding laterally at a side margin along its length, the mistake proofing portion 5 be positioned on the first engine cylinder-body and trimotor cylinder body 8 is arranged towards right side, and the mistake proofing portion 5 be positioned on the second engine cylinder-body 7 and the 4th engine cylinder-body is arranged towards left side.Like this, in order to avoid interfering the first engine cylinder-body consistent with plat part 2 structure of the piston cooling nozzle on trimotor cylinder body 8, and the second engine cylinder-body 7 is consistent with plat part 2 structure of the piston cooling nozzle on the 4th engine cylinder-body, in order to avoid install time take problem by mistake, the mistake proofing portion 5 be positioned on the first engine cylinder-body and trimotor cylinder body 8 is arranged towards right side, the mistake proofing portion 5 be positioned on the second engine cylinder-body 7 and the 4th engine cylinder-body is arranged towards left side, serves the effect of sign and mistake proofing inspection like this.
See accompanying drawing 1-4, a kind of supercharged engine piston cooling nozzle of the present utility model is on the basis of technique scheme, can be: the top of described cylindrical portion 3 is arranged with seal ring 6 that the outer ring of described seal ring 6 and the inwall of described mounting hole fit tightly fixing.Like this, it is fastening more firm that the arranging of seal ring 6 can make between cylindrical portion 3 and mounting hole, decreases assemblage gap, thus avoid cooling oil and enter into cylinder interior by assemblage gap.
Above-mentionedly only a kind of specific embodiment in the utility model to be illustrated; but can not as protection domain of the present utility model; every equivalence made according to the design spirit in the utility model changes or modifies, and all should think and fall into protection domain of the present utility model.
