Temperature control system for a water-cooled internal combustion engine

摘要

A temperature control system for a water-cooled internal combustion engine suitable for use on outboard motors and the like. A water pathway extends along two water-jacketed engine portions. A water supply control means allows a water supply to be selectively directed into one of two possible flow paths within the water pathway. In one flow path direction the water supply is warmed as it passes through the first water-jacketed engine portion so that heated water then passes on to warm the engine in the vicinity of the second water-jacketed engine portion. In the other flow path direction, cool water first passes through the second water-jacketed engine portion and then passes on to the first water-jacketed engine portion, thereby cooling the regions in proximity to both water-jacketed compartments.
