Embodiment Construction

[0014] The features and principles of the present invention will be described in detail below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.

[0015] Such as figure 1 , figure 2 As shown, the invention includes: a left box body 4, a right box body 5, an oil pump combination 6 and a fuel injection nozzle, and the shown left box body 4 and the right box body 5 are fixed by closing bolts 9 to realize the injection The mouth combination 1 is installed between the left box body and the right box body. The fuel injection nozzle seat holes are set on the left box body and the right box body, and the driving pin 3 mounting holes are set on the left box body, and the seat platform of the fuel injection nozzle is inserted into the fuel injection nozzle seat hole. Inside, adjust the angle of the fuel injector so that the fuel injection port of the fuel inj...

Abstract

The invention relates to a motorcycle engine piston cooling mechanism. The cooling mechanism comprises a left box body, a right box body, an engine oil pump assembly and an oil nozzle. The left box body and the right box body are fixed through combined box bolts. Oil nozzle base holes are formed in the left box body and the right box body. Meanwhile, a driving pin installation hole is formed in the left box body, seat stands at the two ends of the oil nozzle are inserted into the oil nozzle base holes, the left end of the oil nozzle is matched with a driving pin, and direction positioning is carried out on the oil nozzle through the driving pin; the oil nozzle base holes are communicated with an oil way, and the left end and the right end of the oil nozzle are in installation clearance sealing with the box bodies through O-shaped rubber sealing rings. The cooling mechanism is unique in structure, simple in appearance and reasonable in arrangement, the spatial arrangement is effectively utilized, the strict oil spraying angle and oil spraying pressure are ensured, an engine piston is effectively cooled, the power is improved, and oil consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of piston cooling for motorcycle engines, in particular to a novel piston cooling mechanism for motorcycle engines. Background technique [0002] At present, piston cooling technology is rarely used in motorcycles. The piston load of the motorcycle engine is heavy, the temperature is high, and the cooling effect is relatively poor. If the piston does not get a good cooling effect, it may cause the deformation of the piston or even the danger of cylinder swelling. If measures are taken to increase the gap between the piston and the cylinder body, abnormal noise and piston offset wear may be caused during the reciprocating operation of the piston, which will affect the normal operation of the engine in severe cases. In the engine, the layout of the oil passage, the flow rate of the oil inlet and the pressure of the oil inlet all have a great influence on the cooling effect. In addition, the structure of the...
