ABSTRACT:
An apparatus for cooling an internal combustion engine has a coolant jacket surrounding the cylinder walls, the combustion chamber domes, and the exhaust runners of the engine. The coolant jacket has formed therein a coolant chamber. A substantially anhydrous, boilable liquid coolant, having a saturation temperature higher than that of water, is pumped through the coolant chamber to cool the metal surfaces of the engine. A radiator is coupled in fluid communication with the coolant chamber to receive coolant flowing therefrom and to reduce the temperature of the coolant by heat exchange therewith. A pump is coupled in fluid communication with the coolant chamber and the radiator to pump the coolant therethrough. The coolant is distributed and pumped at a flow rate so that the coolant vaporized upon contact with the hotter metal surfaces of the engine substantially condenses within the liquid coolant. A vent line is coupled on one end to the coolant chamber and coupled on the other end to an expansion tank. A U-shaped section of the vent line extends above the highest level of coolant in the system. The expansion tank is provided to receive gases, vapor, and/or expanded coolant from the coolant chamber. The expansion tank always holds some coolant to maintain a liquid coolant barrier between the coolant chamber and the ambient atmosphere.
