In the gasoline engine, an exhaust detour passage with a regulating valve is provided in the exhaust system leading to the atmosphere through the exhaust turbine, the upstream side and the downstream side of the exhaust turbine being connected so as to bypass the exhaust turbine. A blow passage branched from the intake passage between the valve and the exhaust gas bypass passage is connected to the exhaust bypass passage or the exhaust passage between the exhaust turbine and the catalytic exhaust purification device, and the blow passage is connected to the pressure downstream from the throttle valve. An exhaust turbocharged engine characterized by being provided with a control valve that opens the blow passage when the vacuum increases.
