And the pipe 62 that constitutes the part of connection pipe 44 forms through blowing out of synthetic resin, thus can easily form crooked connection pipe 44, and the connection pipe 44 that can extend.
In addition; Throttling bodies 45 with engine main body 30 than airfilter 43 by disposing down; And; Be connected on the airfilter 43 and will come from first 44b of downtake portion that the air of this airfilter 43 guides downwards, from first 44c of ascending pipe portion of the lower end counter steer top guiding air of first 44b of downtake portion, from the upper end counter steer below guiding air of second 44c of ascending pipe portion and be connected second 44d of downtake portion on the above-mentioned throttling bodies 45; Be arranged on the connection pipe 44, the scavenge trunk 66 that extends out from the crank case 31 of engine main body 30 is connected being provided with in the portion continuously of first 44b of downtake portion and second 44c of ascending pipe portion, so; Through connection pipe 44 is bent to up and down reciprocatingly; Can constitute connection pipe 44 longer and more compactly, and, can make the oil of coming together turn back to engine main body 30 sides from scavenge trunk 66 once more with the gas leakage of scavenge trunk 66 interior circulations through scavenge trunk 66 being connected on the foot of connection pipe 44.
In addition; The filter case 48 of airfilter 43 comprises: be supported on vehicle body frame F and go up and be connected with the upper tank 49 of the upstream of connection pipe 44, be installed in lower tank 50 on this upper tank 49 removably; The filter element 54 of the decontamination chamber 56 that is divided into decontamination chamber 55 not in the filter case 48 and communicates with connection pipe 44 is accommodated in the filter case 48, is unloading from upper tank 49 under the state of lower tank 50, can carry out upkeep operation; So need not to remove the coupled condition of connection pipe 44 on airfilter 43; Just can unload lower tank 5, and carry out the upkeep operation of filter element 54, can improve maintainability from upper tank 49.
Since on the Fuel Tank 40 attached be provided with the exhaust tube 87 of discharging fuel is configured in Fuel Tank 40 above petrolift 84, so, connect pipeline mechanism 94 up/down perforation Fuel Tanks, the 40 ground configuration between exhaust tube 87 and the fuel injection valve 46; So, with Fuel Tank 40 corresponding parts in, pipeline mechanism 94 can not be projected into the outside; Even constitute in the motor bike of appearance part at Fuel Tank 40; Also can avoid increasing number of components, and avoid reducing the commodity performance of outward appearance, and can do the best and do not make pipeline mechanism 94 be projected into the outside; Can prevent pipeline mechanism 94 is caused useless contact, can make it to be difficult to receive the influence of external environment.
And; The cartridge unit 98 of up/down perforation Fuel Tank 40 is located on this Fuel Tank 40; First fuel hose, 95 perforation cartridge units, 98 ground that constitute at least a portion (being a part among this embodiment) of pipeline mechanism 94 and be connected on the exhaust tube 87 connect up; So the complete cycle through with the upper and lower of cartridge unit 98 is welded on the Fuel Tank 40, can guarantee easily that first fuel hose 95 connects the leak tightness of the part of Fuel Tanks 40.
In addition; Fuel Tank 40 is arranged on the rear frame 24 of a part that constitutes vehicle body frame F; First fuel hose 95 that connects cartridge unit 98 passes the wiring of above-mentioned rear frame 24 ground; So the special use cover that covers first fuel hose 95 need be set, and can not make the long part of first fuel hose 95 be projected into the outside.
In addition; The positive type joint 104 of first quick connector 101 is arranged at least one side at the two ends of first fuel hose 95; Be arranged among this embodiment on the end of second fuel hose, 96 sides, because positive type joint 104 is littler than negative joint diameter, so even have the little gap and the through hole of minor diameter midway at the routing path of first fuel hose 95; Also the wiring of first fuel hose 95 can be easily carried out, the wiring degree of freedom of fuel hose can be improved.
And; Be located at the through hole 99 that above-mentioned positive type joint 104 on first fuel hose 95 can connect the through hole midway of the routing path that is configured in first fuel hose 95, first through hole 97 that is promptly formed by cartridge unit 84 and formed by the liner 100 of the front portion that is assemblied in rear frame 24; So; Can improve the wiring operation property of first fuel hose 95; And since the external diameter of above-mentioned positive type joint 104 less than the internal diameter of first and second through holes 97,99; So can make first fuel hose 95 easily through in cartridge unit 98 and the liner 100, can further improve the wiring operation property of first fuel hose 95, can easily pipeline mechanism 94 be installed on the petrolift 84.
The negative joint 105 of first quick connector 101 is arranged on first fuel hose 95 and constitutes on second fuel hose 96 of pipeline mechanism 94; So can be with any range in first fuel hose, the 95 formation pipeline mechanisms 94 with positive type joint 104, remaining scope can adopt second fuel hose 96 of the common type that is provided with negative joint 105.
In addition; Petrolift 84 is installed on the upper surface of Fuel Tank 40; Cover this petrolift 84, the exhaust tube 87 of this petrolift 84 and the connecting portion of first fuel hose 95 from the top; First fuel hose 95 is installed on the upper surface of Fuel Tank 40 to the pump cover 110 of the portion that is inserted through of the upper end of above-mentioned cartridge unit 98, so can prevent first fuel hose 95 in the pipeline mechanism 94 is produced useless contact to the connecting portion of petrolift 84 sides.
And; Rear at head pipe 22; On vehicle body frame F, fixing the supporting strut 116 that extends to the back upper place; Utilize with cover from the place ahead be sitting in the occupant with the occupant on the vehicle seat 41 about the leg protection cover 129 of two legs be provided with continuously and central authorities' cover 130 coverings of covering body framework F as electronic control unit 117, regulating control 118 and the angle of heel sensor 119 of electric component; So need not be used for the special-purpose member of overlay electronic control unit 117, regulating control 118 and angle of heel sensor 119, can reduce number of components, help cost-cutting.
More than, embodiments of the invention have been described, but the present invention is not limited to the foregoing description, in not breaking away from the scope of the present invention that claims put down in writing, can carry out various design modifications.
