ABSTRACT:
This invention relates to an air cooled horizontal power piston engine and to an improvement for conventional water cooled horizontal power piston engines by which such water cooled engines may be modified for cooling by ambient air. An efficient air cooling system for horizontal power piston engines, with structural features which in operative combination with such engine presents an engine of novel configuration, is described. The water jackets contained within the engine block and cylinder head of a conventional horizontal power piston engine are utilized as the chambers for passage of ambient air through the engine. The cylinder head is modified by providing it with passageways or opening which communicate the internal water jacket of the head to the atmosphere. The liquid cooling radiator unit is displaced by a high volume centrifugal fan blower which is operated by belt drive through the power transmission clutch connected to the engine crankshaft. In operation, the engine operates the blower which supplies a high volume of pressurized air to the water jacket of the cylinder housing of the engine block. The air provided by the blower circulates about the cylinder sleeve of the combustion chamber and passes to the water jacket of the cylinder head after which it is exhausted directly to the atmosphere through the opening provided in the head.
