Claims

[Scope of utility model registration request]

First and second exhaust passages are formed in an exhaust manifold disposed between the engine body and the turbine of the exhaust turbo supercharger, and exhaust gases sent from each cylinder in the engine body are passed through the exhaust manifold. In a turbocharged engine in which exhaust gas is introduced into the exhaust gas introduction part of the turbine through each of first and second exhaust passages, the turbocharged engine is capable of being inserted into the exhaust gas introduction part of the turbine at a connection part of the exhaust manifold with the turbine. a movable partition plate that extends the first and second exhaust airways of the exhaust manifold into the exhaust gas introduction section of the turbine when inserted into the exhaust gas introduction section; In the region, the movable partition plate is held in the first state where it is inserted into the exhaust gas introduction part of the turbine, and in the high speed region where the rotation speed of the engine body rises above a set value, the movable partition plate is inserted into the exhaust gas introduction part of the turbine. A turbocharged engine characterized by being provided with an actuator that switches to a second state in which the exhaust gas is removed from the exhaust gas introduction section.
