ABSTRACT:
A controlled cooling system for a turbocharged internal combustion engine having a heat exchange radiator, liquid coolant to absorb heat from the engine, a pump to circulate coolant through the system, a fan to force air in heat exchange with the engine coolant radiator and a radiator for the charge-air after cooler coolant. The cooling and turbocharge system includes a temperature control valve to direct a portion of the liquid coolant discharged from the engine to the radiator and to direct a portion of the liquid coolant to bypass the radiator in response to the temperature of the liquid coolant after discharge from the engine. A liquid subcooler heat exchanger lowers the temperature of the liquid coolant by passing the coolant in heat exchange with forced air from the fan. A flow control valve directs a portion of the liquid coolant discharged from the radiator to the subcooler heat exchanger and the remainder of the liquid coolant to the engine. An aftercooler heat exchanger lowers the temperature of the combustion air discharged from the turbocompressor by passing the combustion air charge in heat exchange with the liquid coolant from the subcooler heat exchanger.
