PURPOSE:To prevent the thermal damage of a supercharger and exhaust parts, by detecting the temperature of exhaust gas flowing into a turbine casing and by controlling the supercharging pressure to keep the temperature below a prescribed level. CONSTITUTION:An exhaust temperature detector 3 and a control circuit 5 are provided to detect the temperature of exhaust gas flowing into a turbine casing 23 and regulate a supercharging pressure controller 4 to keep the temperature below a prescribed level. As a result, the thermal damage of a supercharger 2 and exhaust parts is prevented and the excessive thickening of the air-fuel mixture is avoided to improve the fuel efficiency.
