Abstract
A spark timing control system for an internal combustion engine features an ignition device, a power increase detector, a control device, and a temperature detector. The ignition device produces a spark in a combustion chamber of the engine. The power increase detector senses an increase in the output power required of the engine. The control device is connected to the ignition device for controlling timing of the spark, and is also connected to the power increase detector for retarding the spark timing in terms of engine crank angle when the engine is required to increase its output power. The temperature detector senses the temperature of engine coolant and suspends the retardation of the spark timing due to the engine power increase in response to the temperature of engine coolant.
