摘要：
Regarding an engine device including a supercharger, it is an object to provide the engine device that can execute the control of an air flow rate with excellent responsiveness with respect to variation in load. An engine device 21 of the present invention of the instant application executes the control of the opening degree of the main throttle valve V1 when engine load is in a low load area. In contrast, when the engine load is in a medium-to-high load area, an engine control device 73 sets a main throttle valve V1 to a predetermined opening degree and executes the control of the opening degree of an air supply bypass valve V2. In the medium-to-high load area on which variation in load exerts great influence, bypass valve control with excellent responsiveness is executed, so that the severe deficiency of the flow rate of the air can be suppressed with respect to the variation on load, and the engine device 21 can be smoothly operated.
