Abstract
An air-cooled engine includes a cooling fan mounted at one end of a crankshaft supported in a crankcase, and a shroud for guiding cooling air flow produced by the cooling fan encloses an outer periphery of a cylinder block. The engine further includes an auxiliary cooling fan mounted at the other end of the crankshaft, together with an auxiliary shroud for guiding cooling air flow produced by the auxiliary cooling fan to an outer periphery of the crankcase, so that the absorption of heat from the cylinder block by the crankcase can be effectively increased. Thus, it is possible to enhance the effect of cooling of an air-cooled engine without increasing the size of the cooling fan and the shroud thereof.
