Abstract
A fuel supply control system for use in an internal combustion engine equipped with an exhaust gas recirculation system is disclosed which determines an amount of fuel supplied to the engine in accordance with intake air flow derived from engine suction vacuum and engine speed and corrected in accordance with exhaust gas recirculation flow. The engine suction vacuum and exhaust gas recirculation flow measurements are made in accordance with pressure measured at suitable points by semiconductor pressure sensors.
