A nonlinear control method for automotive fuel-injection systems is developed using the theory of variable structure systems. This fuel-injection control method is formulated to be compatible with production sensors and actuators, and its feasibility and potential benefits are demonstrated using a research automobile. The motivation for this research stems from the fact that fuel-injection control is a difficult control problem due to the nonlinear and complex nature of engine dynamics and due to the limitations imposed by a switching-type feedback sensor.
