ABSTRACT:
A method and apparatus for detecting engine overheating and controlling engine ignition timing utilizes a single temperature sensor. The temperature sensor is positioned adjacent a cylinder head of an engine. A rate of engine temperature increase is calculated based on engine temperature information produced by the temperature sensor, and engine speed is regulated based on the calculated rate of engine temperature increase. Ignition timing is also controlled in response to the engine temperature information produced by the temperature sensor, and the engine speed is regulated to a predetermined speed value whenever the engine temperature exceeds a predetermined temperature value.
