PURPOSE:To prevent engine stall where fuel injection is stopped under deceleration while resumed upon dropping below specific rotation by increasing next injecting rotation upon dropping below engine stall alarming rotation after fuel injection. CONSTITUTION:On the basis of rotary pulse from ignition coil 1 corresponding with engine rotation N and the output voltage from intake air quantity meter 2, basic pulse generating circuit 3 will operate the basic injection to produce corresponding basic pulse. When the engine rotation due to rotary pulse is higher than predetermined level while an idle switch 5 is turned on and the water temperature to be detected through a water temperature sensor 6 is higher than predetermined level, fuel cut signal is produced from fuel cut circuit 4 to resume fuel injection upon droppage of engine rotation below recovery rotation. While upon droppage of engine rotation below engine stall alarming rotation after resuming of fuel injection, the rotation when resuming fuel injection is incremented through correction circuit 11.
