Abstract
A temperature sensor is provided for detecting temperature of exhaust gas in an exhaust passage of a two-cycle engine. The temperature is compared with a reference temperature for activating a catalytic converter. When the temperature is lower than the reference temperature, the ignition timing and the fuel injection timing of the engine are retarded. The quantity of injected fuel is increased so as to compensate reduction of engine power caused by retarding the ignition timing.
