Abstract

An engine control device controls an engine. The engine includes a turbocharger, a waste gate valve, and a throttle. In a predetermined low load region, the engine control device performs first control in which the waste gate valve is opened at a predetermined opening degree or more and output adjustment is performed by an opening degree of the throttle. In a predetermined high load region, the engine control device performs second control in which the throttle is opened at a predetermined opening degree or more and output adjustment is performed by an opening degree of the waste gate valve. When a torque limiting request is generated in the high load region, the engine control device performs third control in which the waste gate valve is substantially fully closed and output adjustment is performed by the opening degree of the throttle.
