Abstract
A kind of motorcycle twin cylinder engine piston cooling device, comprise two cylinder bodies, piston is provided with in cylinder body, piston is connected with crankshaft-link rod assembly, crankshaft-link rod assembly is arranged in crankcase, the position be positioned in crankcase above two pistons is respectively equipped with fuel ring pipe, and fuel ring pipe is provided with multiple oil nozzle.During engine operation, the multiple oil nozzles on two fuel ring pipes spray cold oil facing to a piston respectively, cool piston comprehensively.The present invention sprays cold oil by multiple oil nozzles that fuel ring pipe is arranged to piston, has increased substantially the cooling effect of piston, has also improved the lubrication effect between piston and cylinder body simultaneously.
Description
Technical field
The present invention relates to a kind of motorcycle twin cylinder engine piston cooling device.
Background technique
The patent No. be 201320352629.3 Chinese patent disclose a kind of motorcycle twin cylinder engine piston cooling device, comprise cylinder body, piston, crankshaft-link rod assembly and crankcase, piston is arranged in cylinder body, piston is connected with crankshaft-link rod assembly, crankshaft-link rod assembly is arranged at the inner chamber of crankcase, is provided with the oil nozzle be connected with oil pipe, during engine operation in crankcase, oil nozzle sprays cold oil to piston, plays the effect of cooling piston.Although this cooling unit has certain cooling action to piston, owing to only having an oil nozzle to spray cold oil, therefore, the cooling effect of piston is bad.
Summary of the invention
The object of the present invention is to provide a kind of motorcycle twin cylinder engine piston cooling device of good cooling results.
The object of the present invention is achieved like this, a kind of motorcycle twin cylinder engine piston cooling device, comprise cylinder body, piston, crankshaft-link rod assembly and crankcase, crankshaft-link rod assembly is arranged in crankcase, cylinder body is two, is provided with piston in cylinder body, and piston is connected with crankshaft-link rod assembly, the position be positioned in crankcase above two pistons is respectively equipped with fuel ring pipe, and fuel ring pipe is provided with multiple oil nozzle.During engine operation, the multiple oil nozzles on two fuel ring pipes spray cold oil facing to a piston respectively, cool piston comprehensively.
In order to make cold oil be distributed in uniformly on piston, improve cooling effect further, oil nozzle is distributed on fuel ring pipe.
In order to simple and compact for structure, fuel ring pipe is arranged on the internal chamber wall of crankcase.
In order to ensure that the blunt cold oil penetrated of oil spout on fuel ring pipe is all ejected on piston, the external diameter of fuel ring pipe is not more than the diameter of piston.
Fuel ring pipe is provided with filler opening, and filler opening is connected with fuel tank by the oil pipe that crankcase is arranged.
The present invention has following beneficial effect:
1, motorcycle twin cylinder engine piston cooling device of the present invention correspondence in crankcase, above piston arranges fuel ring pipe, sprays cold oil, good cooling results by multiple oil nozzles that fuel ring pipe is arranged to piston.
2, motorcycle twin cylinder engine piston cooling device of the present invention has the function of piston being carried out to Cooling and Lubricator concurrently simultaneously, not only increases cooling effect, and improves lubrication effect.
3, structure of the present invention is simple, is easy to realize.
