  • Abstract
    A control scheme is designed to limit air-fuel ratio excursions and track driver-demanded torque for a 4-cylinder engine during rapid changes in throttle position. The new control scheme is based on joint management of air and fuel flow into the cylinders using secondary throttles placed before the intake ports of the cylinders, in combination with standard fuel injectors
