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 circuit, 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, cold oil is skewness on piston, and therefore, cooling effect is bad; Meanwhile, this structure fueling injection equipment can only intermittent type oil spout, and when low engine speed travels, piston heat load is lower, does not need oil spout, now still sprays cold oil to piston, thus engine oil pressure when reducing low cruise.
Model utility content
The purpose of this utility model is to provide a kind of good cooling results and controlled motorcycle twin cylinder engine piston cooling device.
The purpose of this utility model realizes like this, a kind of motorcycle twin cylinder engine piston cooling device, comprise cylinder body, piston, crankcase and crankshaft-link rod assembly, crankshaft-link rod assembly is arranged in crankcase, cylinder body is two, and be respectively equipped with piston in two cylinder bodies, piston is connected with crankshaft-link rod assembly, the top being positioned at two pistons in crankcase is respectively equipped with fuel ring pipe, and fuel ring pipe is provided with multiple oil nozzle; Fuel ring pipe is connected with injector control valve, and injector control valve comprises the valve body with cavity, and valve body is provided with oil inlet passage and oil outlet, oil outlet is communicated with fuel ring pipe, be provided with annular plug in oil inlet passage, annular plug port is provided with ball valve, is provided with spring between ball valve and oil outlet.When engine speed is less, engine oil pressure is less, and spring extends naturally, and ball valve contacts with annular plug and blocks oil inlet passage; When engine speed is enough large, engine oil pressure increases and compressing ball valve, Compress Spring, produce gap between ball valve and annular plug, thus make machine oil enter cavity by oil inlet passage, enter fuel ring pipe from oil outlet, be ejected on piston by multiple oil nozzle, piston is cooled comprehensively.
In order to make lubricant oil evenly be ejected on piston, oil nozzle is distributed on fuel ring pipe.
Oil outlet is communicated with fuel ring pipe by oil pipe.
In order to compact structure, fuel ring pipe is arranged on the inwall of crankcase.
In order to ensure that cold oil is 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 sump by the oil circuit that crankcase is arranged.
The utility model has following beneficial effect:
1, the utility model motorcycle twin cylinder engine piston cooling device arranges fuel ring pipe respectively in crankcase, above two pistons, by multiple oil nozzles that fuel ring pipe is arranged, respectively cold oil is sprayed to two pistons, increased substantially the cooling effect of piston.
2, the fuel ring pipe in the utility model is connected with injector control valve, can control to spray cold oil according to the speed of engine speed, overcome the problem of engine oil pressure when prior art is still sprayed cold oil thus reduces low cruise piston when low engine speed travels, when can make low cruise, motor maintains higher oil pressure.
