Embodiment Construction

[0064] Hereinafter, the mode of the present invention will be explained according to an embodiment of the present invention with reference to the drawings.

[0065] As shown in FIG. 1, the main frame 15 of the scooter includes a head pipe 18, the head pipe 18 operably accommodates the front fork 16, and the front wheel WF is journaled with the steering handle 17 connected to the front fork 16. A down tube 19 extends backward and downward from the head tube 18. The pair of left and right lower frame pipes 20 extend rearward, and the pair of left and right lower frame pipes 20 have front ends respectively fixed to the lower side of the lower pipe 19. The pair of left and right rear frame pipes 21 are integrally connected to the rear end of the lower frame pipe 20. Each rear frame pipe 21 includes a rising frame portion 21a and an upper frame portion 21b extending backward and upward from the rear end of each lower frame pipe 20, and the upper frame portion 21b extending from the rea...

Abstract

An internal combustion engine with forced air cooling that effectively cools spark plugs, wherein a cylinder block and a cylinder head from which cooling fins protrude are covered by a shield, thereby forming a cooling air passage between the shield, the cylinder block and the cylinder head. A cooling fan for ventilating cooling air drawn from outside the shroud to the cooling air passage is associated with and connected to the crankshaft. An air outlet for discharging the cooling air that has flowed through the cooling air passage to the outside is formed to the hood. By partially shortening or removing the fins protruding from the periphery of the cylinder block, the cutout space is formed to a part of the periphery of the cylinder block. A first protrusion and a second protrusion are formed to the shield, the first protrusion protrudes inwardly along the cutout space, and the second protrusion is located at a position between the second protrusion and the first protrusion at a position where a spark plug attached to one side of the cylinder head is located Protruding inwards.

Description

Technical field [0001] The present invention relates to an internal combustion engine with forced air cooling, in which a cylinder block is connected with a crankcase, the crankcase rotatably accommodates the crankshaft, and radiating fins protrude from the cylinder block. The cylinder head is connected with the cylinder block and has an ignition plug attached thereto. The shielding cover forms a cooling air passage between the shielding cover, the cylinder block and the cylinder head. The cooling fan is provided for ventilating the cooling air sucked from the outside of the shielding cover to the cooling air passage, and the cooling fan is associated with the crankshaft and connected to the crankshaft. The air outlet is provided to discharge the cooling air flowing through the cooling air passage to the outside, and the cooling air passage is formed to the shielding cover. Background technique [0002] Japanese Patent Document JP-A No. H7-332084 discloses an internal combustion ...
