Abstract
A fuel injection control system performs fuel cut-off operation intermittently so that engine output torque may not fluctuate at significant level to cause jerking at the transition from fuel injecting state to fuel to fuel cut-off state and at fuel resumption after fuel cut-off. Intermittnetly cutting off the fuel delivery for the engine cylinders, engine output torque drop at the fuel injecting state and fuel cut-off state can be reduced for reducing magnitude of jerking.
