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

In an engine generator having a work generator arranged at the upper side of an engine of a vertical crank shaft type, the output shaft of the engine projects upwards from the engine crank case so as to be connected to the rotor of the work generator. And the stator is arranged so as to encircle the rotor and to be encircled by an air induction casing. A cooling fan of a centrifugal blower type is located at the upper end of the rotor shaft with the blades thereof directed to the side of the generator so as to supply a cooling air flowing upwards to both the interior and the exterior of the stator during operation.
