Air-cooled V-shaped engine

摘要

An air-cooled V-shaped engine comprises a throttle body (10) and a flow-dividing plate (9) arranged ahead of a central cooling-air passage (8). The flow-dividing plate (9) is provided in a fan case (5) at a position forwardly of the throttle body (10) and has a bottom-plate portion (14) disposed at a position lower than the throttle body (10). The flow-dividing plate (9) divides the cooling air generated by an air-blowing fan (7) toward left and right sides of the central cooling-air passage (8). In this air-cooled V-shaped engine, the fan case (5) has a ceiling wall a central portion (11) of which is positioned just above the bottom-plate portion (14) of the flow-dividing plate (9). The central portion (11) of the ceiling wall of the flow-dividing plate (9) is provided at a position higher than the throttle body (10) as well as the central side portions (12), (12) of the ceiling wall, led out of the central portion (11) in a left and right directions.
