Abstract
An internal combustion engine equipped with a supercharger including a bypass passage avoiding a turbine and disposed in parallel to an exhaust pipe, and a bypass valve mounted in the bypass passage for controlling the flow rate of exhaust gas flowing through the exhaust pipe. A control method for the internal combustion engine equipped with a supercharger wherein an air intake is compressed by a compressor coaxially connected to the turbine driven by exhaust gas flowing in the exhaust pipe to supply a supercharger pressure to the engine; the temperature of exhaust gas flowing into a casing of the turbine is sensed by a temperature sensor; and the pressure of the air intake supplied to the engine as the supercharger pressure is controlled when the temperature sensor produces a signal, to thereby keep the temperature of the exhaust gas at a level below a predetermined value.
