ABSTRACT:
The electric drive motor of an internal combustion engine radiator cooling fan that is arranged to be energized by the output potential of a dynamoelectric generator driven by the engine is supplied with operating potential in such a manner that the average supplied drive motor power is directly proportional to engine speed while engine temperature is within the range between a predetermined first temperature and a predetermined higher second temperature and the engine is operating within a selected speed range.
