ABSTRACT:
A temperature regulating system for a turbo charged engine and the compressed charging air from the turbo charger is disclosed. The heat regulating system employs coolant fluid which flows through the engine to transfer heat from the engine. Depending on the operating conditions of the engine the heated coolant from the engine is distributed among one or more of a plurality of flow paths. In one of the flow paths the coolant flows through a primary radiator where the coolant is cooled. A fan forces air into contact with the radiator to transfer heat from the radiator. A portion of the coolant exiting the radiator flows through a subcooler where the coolant is further cooled. The coolant from the subcooler may be directed to the charged air cooler for cooling the compressed air before flowing back to the engine. In a second flow path, coolant which has not flowed through the radiator, flows through the charged air cooler to heat the compressed air. A controller responds to input from at least one sensing device and actuates a valving arrangement to distribute the coolant from the engine among the flow paths.
