Abstract
An engine device executes the control of the opening degree of a main throttle valve when engine load is in a low load area. In contrast, when the engine load is in a medium-to-high load area, the engine device sets the main throttle valve to a predetermined opening degree and executes the control of the opening degree of an air supply bypass valve.
