Abstract
A supercharged internal combustion engine includes an intake passage, a supercharger arranged in the intake passage, an exhaust passage, and a catalytic converter arranged in the exhaust passage. A supercharging pressure control system for the engine controls the opening of a supercharging pressure control valve for controlling supercharging pressure of intake air supplied to the engine by the supercharger. When the temperature of the catalytic converter falls outside a predetermined range, the opening of the control valve is controlled in a manner such that the temperature of the catalytic converter is brought into the predetermined range.
