Abstract

A fuel supply control system for controlling a fuel amount to be supplied to an internal combustion engine having an exhaust gas recirculation mechanism comprising an exhaust gas recirculation passage connected between an intake pipe and an exhaust pipe, and an exhaust gas recirculation valve provided in the exhaust gas recirculation passage, is disclosed. The fuel amount to be supplied to the engine is corrected according to a pressure difference between an intake pressure detected when opening the exhaust gas recirculation valve and an intake pressure detected when closing the exhaust gas recirculation valve.
