Abstract
The utility model belongs to the lubricating and cooling technical field of an engine of a motorcycle, referring to a spray cooling system for an engine piston of the motorcycle. The spray cooling system mainly comprises a left box (3), a right box (8), a cylinder body (2) and a piston (1), wherein the cylinder body (2) for mounting the piston (1) is arranged on a combination surface of the left box (3) and the right box (8); the left and right boxes (3, 8) are respectively equipped with an oil passage (4, 7); the two oil passages (4, 7) are communicated with each other; the oil passage on the right box is communicated with a main oil path; both the two oil passages (4, 7) are equipped with oil spraying holes (5, 6) which are directed to the top surface of the back of the piston. The spray cooling system increases cooling and lubrication effect of the piston effectively.
Description
Technical field
The utility model belongs to the lubricated and cooling technology field of motorcycle engine, relates generally to a kind of spray cooling system that is used for motorcycle engine piston.
Background technique
In each component of motor, piston is as key components and parts, and its operating conditions is very abominable: work under very high Sliding velocity and very big load pressure on the one hand, piston directly bears the alternation effect of high-temperature fuel gas on the other hand, the heat load height, thermal stress is big.In order to guarantee the reliability of pistons work, prolong the working life of piston simultaneously, must constantly cool off and lubricate piston.For this reason, adopted a series of technological schemes to solve this difficult problem in the industry.At present, the technological scheme that most motors adopt is: the rotation by connecting rod makes machine oil be splashed to the piston back, makes part machine oil be penetrated into cylinder inner wall by the oilhole of piston ring land simultaneously, thereby reaches cooling and lubricated effect.But along with the increase of motorcycle engine discharge capacity, piston institute affected by hot loading increases, and utilizes connecting rod can not satisfy actual demand to the mode of piston splash lubrication and cooling.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of spray cooling system that is used for motorcycle engine piston, makes it can effectively improve the cooling and the lubrication effect of piston.
The utility model is finished the technological scheme that its invention task taked: a kind of spray cooling system that is used for motorcycle engine piston, and described spray cooling system mainly comprises left box body, right case, cylinder block and piston; The cylinder junction surface of described left box body, right case is provided with the cylinder block that is used to settle piston; On described left and right casing, be provided with oil duct; Described two oil ducts are connected, and the oil duct on the right case is connected with working connection simultaneously; Be provided with the nozzle opening that points to piston back end face on described two oil ducts.
Described two its axis of nozzle opening are all parallel with left and right casing junction plane, and distance is 10 ± 5mm.
The angle α of the axis of described two nozzle openings and cylinder pilot hole longitudinal center line is 40 ± 10 °.
Described two its diameters of nozzle opening are 0.8 ± 0.3mm.
A kind of spray cooling system that is used for motorcycle engine piston that the utility model proposes adopts above-mentioned technological scheme, effectively raises the cooling and the lubrication effect of piston.

Embodiment
With embodiment the utility model is illustrated in conjunction with the accompanying drawings:
A kind of spray cooling system that is used for motorcycle engine piston, described spray cooling system mainly comprise left box body 3, right case 8, cylinder block 2 and piston 1; On the junction plane of described left box body 3, right case 8 cylinder block 2 is installed, the cylinder block cylinder sleeve cooperates with the cylinder mounting hole of left and right casing, and piston 1 places in the cylinder block 2; On described left and right casing 3,8, respectively be provided with oil duct 4,7; Oil duct 4,7 on the left and right casing is combined into an oil duct after mould assembling, and is connected with working connection by the outer oil duct connecting bolt of right case; On described two oil ducts 4,7, respectively be provided with the nozzle opening 5,6 that points to inner chamber top, piston back.Described two nozzle openings, 5,6 its axis are all parallel with left and right casing junction plane, and distance is 10 ± 5mm; The angle α of the axis of described two nozzle openings 5,6 and cylinder pilot hole longitudinal center line is 40 ± 10 °; Described two nozzle openings, 5,6 its diameters are 0.8 ± 0.3mm
During use, when piston 1 arrives top dead center, can avoid wrist pin and connecting rod, directly arrive at the exhaust side of piston back end face, effectively raise the cooling and the lubrication effect of piston from the machine oil that nozzle opening 5,6 ejects.
