Abstract:
An engine cooling system, comprising:at least one engine coolant chamber formed adjacent to heat-emitting components of the engine;a substantially anhydrous, boilable liquid coolant having a saturation temperature higher than that of water and received within the at least one engine coolant chamber;an expansion chamber coupled in fluid communication between the at least one engine coolant chamber and the engine's ambient atmosphere for receiving coolant from the at least one engine coolant chamber and permitting coolant flow between the expansion chamber and the at least one engine coolant chamber with thermal expansion and contraction of the coolant; andat least one of an auxiliary heating circuit, at least one heat-emitting component of the engine, and a desorption region, for heating coolant within the expansion chamber to a temperature at or above a predetermined temperature during engine operation and vaporizing substantially all water from the coolant to thereby maintain the coolant in a substantially anhydrous state.
