An object of this invention is to accurately control an exhaust air-fuel ratio, even when a WGV (waste gate valve) is operating. An ECU is equipped with a turbine passing path constant At that corresponds to a time required for exhaust gas to flow to an air-fuel ratio sensor via a turbine of a turbosupercharger , and a bypass path constant Ab that corresponds to a time required for exhaust gas to flow to the air-fuel ratio sensor via a bypass passage . The ECU calculates first and second fuel injection correction amounts Δt and Δb in which the path constants At and Ab are reflected, respectively. When executing air-fuel ratio feedback control, the ECU 60 selects one of the fuel injection correction amounts Δt and Δb based on at least an open or closed state of the WGV , and corrects a fuel injection amount using the selected fuel injection correction amount. It is thus possible to appropriately compensate for differences in exhaust path lengths and air-fuel ratio fluctuations that arise due to opening or closing of the WGV 1.
