Abstract

A first supercharger and a second supercharger are disposed in series in intake and exhaust passages. In a B region in which both the supercharging effects of the first and second superchargers are utilized, the opening of an exhaust control valve disposed in a passage for bypassing the turbine of the first supercharger is set to an intermediate degree, and the opening of an intake control valve disposed in a passage for bypassing the compressor of the first supercharger is set to the minimum. In a C region in which the supercharging effect of only the second supercharger is utilized, both the openings of the exhaust control valve and the intake control valve are set to the maximum. When the control region shifts from B region to C region as result of acceleration of the vehicle, the fuel injection amount is reduced over a predetermined period immediately after the shift.
