。A compressor linked to the exhaust turbine installed in the exhaust passage is installed in the intake passage, while a secondary air introduction passage is provided that opens into the exhaust passage, and a reed valve is inserted in the middle of this introduction passage. In a secondary air introduction device for an internal combustion engine with a turbocharger that introduces secondary air into the exhaust passage, the secondary air is introduced into the turbine downstream exhaust passage through the intake passage between the compressor and the throttle valve and the secondary air introduction passage on the back of the reed valve. An internal combustion engine with a turbocharger, characterized in that a bypass passage communicating with the engine is provided, a solenoid valve is interposed in the middle of the bypass passage, and a control means is provided to open the solenoid valve for a set time when the engine decelerates. Secondary air introduction device.
