PURPOSE:To prevent a catalyst from being deteriorated in high load by not increasing injected fuel in warming an engine even under conditions of high load, and by delaying, after warming the engine, the timing of the fuel increase in response to the temperature of engine cooling water in the high load conditions. CONSTITUTION:The captioned control device has fuel increase reference timing set means (b) for delivering a first signal for setting fuel increase reference timing when any load applied to an internal-combustion engine (a) is more than a first prescribed value, and engine warming state judging means (c) for delivering a second signal when temperature of cooling the engine is more than a prescribed value. Said fuel increase timing is delayed by fuel increase timing correcting means (e) by delay time corresponding to the engine cooling water temperature provided at an output of delay time memory means (d) only when the first and second signals are entered from said both means (b) and (c). Thus, fuel injection for the internal-combustion engine is controlled via fuel injection control means (f) in conformity with an output from the correcting means (e). |
