Title: Evaporative cooling system of internal combustion engine

Abstract

This patent describes an evaporative cooling system of an internal combustion engine, 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 the coolant is discharged in gaseous state through an outlet port formed in the engine; a condenser into which the gaseous coolant from the coolant jacket of the engine is introduced to be liquefied; a lower tank connected to the condenser to collect therein the coolant which has been liquefied by the condenser, the lower tank having a bottom which is submerged in the liquefied coolant; an electric pump by which the liquid coolant in the lower tank near the bottom of the same is pumped into the coolant jacket through the inlet port of the engine; conduit means connecting the outlet port, the condenser, the lower tank, the electric pump and the inlet port thereby to form a coolant circulation circuit; and a capacity variable tank fluidly connected through a conduit to the lower tank to temporarily capture therein air remaining in the coolant circulation circuit during operation of the cooling system, the conduit being connected to an uppermore » portion of the tank. The upper portion is empty of the liquid coolant under normal operation of the cooling system.« less
