ABSTRACT:
A system for preventing overheating of an engine for a vehicle includes a revolution rate detector for detecting the rate of revolution of the engine carried on the vehicle, a device for reducing an engine power output in response to a value detected in the revolution rate detector exceeding a preset revolution rate, a device for predicting overheating of the engine, and a preset revolution rate correcting device for reducing the preset revolution rate in accordance with a reduction of the vehicle velocity in reply to prediction of an engine overheat condition by the overheat predicting device. An overheating due to an engine racing condition during vehicle travelling is prevented in view of an engine cooling effect provided by flowing air.
