ABSTRACT:
A supercharged engine intercooler includes a coolant jacket in heat exchange with the hot compressed air from the supercharger. The coolant in the jacket is permitted to boil and the vapor condensed in a radiator. The rate of condensation during high engine load is maintained sufficiently high to induce sub-atmospheric pressures within the radiator and coolant jacket which lowers the boiling point of the coolant, while during low load operation the rate of condensation can be reduced to raise the pressure in the coolant jacket and thus the boiling point of the coolant to rise above 100.degree. C. Upon stoppage of the engine, the coolant jacket and radiator are completely filled with liquid coolant to prevent contaminating atmospheric air from leaking into the system.
