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.

Abstract: A method for controlling an engine for a marine vessel which includes, when a sudden fluctuation of a load is to be generated due to connecting or disconnecting of a load at a low speed of the engine, the step of advancing the spark ignition timing by a few degrees at the time the connecting or disconnecting is performed. A different feature is a method which includes, when the throttle opening of an engine for a marine vessel is changed from a predetermined opening degree to a substantially closed state, the step of advancing the spark ignition timing by a few degrees.
