Abstract
In a forced-circulation type water-cooling system for a horizontal internal-combustion engine, a radiator is located roughly at the same height as an engine body in a surrounding space outside a cylinder head and is positioned at a lateral side of the engine body of the horizontal internal-combustion engine. A cooling water inlet for a water jacket and a pump mounting seat for a water pump are provided at one of the front and back opposite sides of the cylinder head, at the same side as where an engine a rotation shaft such as crankshaft of the engine or a gear casing thereof projects from one of the front and back opposite sides of the engine body. The water pump is mounted on the pump mounting seat with its pump shaft extending in the fore and back direction. A pump driving wheel is fixedly secured to the engine rotation shaft, and a pump input wheel is fixedly secured to the pump shaft. The pump driving wheel and the pump input wheel are interlockingly connected to each other through a wrapping connector. The cooling water within the radiator is adpated to be delivered under pressure to a water jacket and circulated to the radiator by the water pump.
