ABSTRACT:
A liquid-cooled, vertical shaft type combustion engine is provided with a duct utilizing a stream of cooling air induced by a cooling fan to cool various parts of the combustion engine. The combustion engine includes an engine body, a crankshaft accommodated in the engine body so as to extend in a vertical direction, at least one engine cylinder head disposed at a front portion of the engine body, a radiator mounted above the engine body for circulating an engine coolant, a duct positioned below the radiator, and a cooling fan operatively accommodated within the duct. The duct has at least a front discharge opening and side discharge ports defined in a peripheral wall for discharging a stream of cooling air induced by the cooling fan, in a direction forwardly of the engine body and in a direction slantwise forwardly of the engine body.
