ABSTRACT:
A boiling liquid coolant system for a vehicular internal combustion engine which operates at a virtually constant predetermined pressure and predetermined temperature having a condenser which assures that all vaporized coolant is condensed under all engine operating conditions by matching the rate of condensation of vaporized coolant in the condenser to the rate vaporized coolant is generated by the engine and flows to the condenser during operation of the engine. In one embodiment, an electrically-driven fan is actuated by a thermal or pressure sensitive switch in the condenser for assuring an adequate flow of ambient air across the condenser tubes during high ambient air temperature engine operating conditions, e.g., low speed, under load or stationary idle conditions of engine operation, and during the hot soak period after engine shutdown. Condensate may be returned to a gravity supply tank by either an electric or an engine-driven pump, and a non-return flow valve assures that vapor cannot flow from the separation tank of the system to the sump in the absence of the flow of liquid coolant from the sump to the separation tank. A pipe may connect the upper and lower parts of the engine cooling jacket through a pump for positive direct circulation, without heat loss, of liquid coolant in the jacket to shorten engine warm up time. Other features include a perforated inlet tube extending into a vapor separator/condenser supply tank, a U-trap in the liquid coolant supply line, a combined pressure/vaccum relief vent valve, and a passenger compartment heater and oil temperature control integral with the separation tank.
