TH20308B - Air-cooled engine - Google Patents

Abstract

The DC60 (13/10/47) air-cooled engine is combined with an optimized cooling fan. Installed at one end of the crankshaft that are supported in Crank room And cover for navigation The cooling air flow produced by the cooling fan surrounds the outer perimeter of the engine block and is further fitted with an additional cooling fan installed down. To the other end of the crankshaft And an additional cover for condensing air flow The heat generated by the additional cooling fan goes to the outer perimeter of the crankcase, thus increasing the heat gain from the cylinder block by the crankcase. It is therefore possible to increase the cooling effect of a cooled engine. With more air without increasing the size of the cooling fan and shield.
