Abstract
The utility model provides a motorcycle bi -block engine piston cooling device, includes two cylinder bodies, is equipped with the piston in the cylinder body, and the piston is connected with crankshaft connecting rod assembly, and crankshaft connecting rod assembly sets up in the crankcase, and the position that is located two pistons top in the crankcase is equipped with annular oil pipe respectively, and annular oil pipe is last to be equipped with a plurality of fuel sprayers. The engine during operation, a plurality of fuel sprayers on the two rings shape oil pipe cool off the piston respectively facing to a piston jet cooling oil comprehensively. The utility model discloses a plurality of fuel sprayers of the last setting of annular oil pipe are oily to piston jet cooling, have increased substantially the cooling effect of piston, have also improved the lubricated effect between piston and the cylinder body simultaneously.
Description
Technical field
The utility model 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.
Model utility content
The purpose of this utility model is the motorcycle twin cylinder engine piston cooling device providing a kind of good cooling results.
The purpose of this utility model realizes 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 utility model has following beneficial effect:
1, the utility model motorcycle twin cylinder engine piston cooling device 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, the utility model motorcycle twin cylinder engine piston cooling device has the function of piston being carried out to Cooling and Lubricator concurrently simultaneously, not only increases cooling effect, and improves lubrication effect.
3, the utility model structure is simple, is easy to realize.
