Abstract:
A cooling system for an internal combustion engine, comprising:(a) a pump that is controlled to circulate cooling water in a cooling circuit that includes the internal combustion engine; (b) a container that reserves high-temperature cooling water heated by said internal combustion engine; and (c) a cooling water unit adapted to provide a higher flow rate through the internal combustion engine and the container when transferring heat from the high-temperature cooling water reserved in the container to the internal combustion engine during warm up, than when introducing and reserving the high-temperature cooling water heated by said internal combustion engine into said container, wherein the warm up is conducted before cranking of the internal combustion engine and the cooling water unit is adapted to provide at least a high flow rate when a hot water heating control is to be performed, and a low flow rate when a heat accumulating control is to be performed.
