Hayashi, Y

In a boiling liquid cooling system for an engine which generates heat when operated, an arrangement is described comprising: means defining in the engine a coolant jacket into which coolant is introduced in liquid state through an inlet port formed in the engine and from which coolant is discharged in gaseous state through an outlet port formed in the engine; a radiator into which gaseous coolant from the outlet port is introduced to be liquefied; a separate coolant reservoir into which the liquefied coolant from the radiator is introduced; an electric pump by which the liquid coolant in the reservoir is pumped to the coolant jacket through the inlet port of the coolant jacket; a first conduit connecting the radiator, the separate coolant reservoir and the electric pump to form a coolant circulation circuit which extends between the inlet and outlet ports of the coolant jacket; and at least one electromagnetic valve associated with the coolant circulation circuit to control flow of the coolant in the circuit, wherein the separate coolant reservoir, the electric pump and the electromagnetic valve are positioned close to the engine proper so as to effectively absorb heat generated by the engine.
