ABSTRACT:
An internal combustion engine cooling system incorporating a motor-assisted turbofan is disclosed. The turbine-driven fan is increased in rotational speed by energizing a motor attached to the turbine fan shaft from an outside power source to provide required cooling air flow. The cooling air system of the invention also includes a ducted fan for supplying cooling air for one or more heat exchangers, and is controlled via inputs from an engine speed sensor for providing a motor operating signal, a flow sensor downstream of the heat exchangers for providing a motor operating signal, and temperature sensors located throughout the cooling circuits.
