Abstract
An electronic controlled fuel injection system is disclosed for use in an internal combustion engine including a plurality of cylinders each fitted with a fuel injection valve. The system comprises a fuel injection control circuit timed to engine rotation for providing a drive pulse signal to the fuel injection valves. A deceleration detecting circuit detects deceleration of the engine in accordance with the positions of the associated throttle valve and foot brake. A coupling circuit is responsive to engine rotational speed for allowing or impeding the passage of the drive pulse signal to the fuel injection valves during deceleration.
