Abstract

When a load on an engine device is lower than a first predetermined load falling within a low load range, feedback control is performed on a main throttle valve. When the load is higher than the first predetermined load, map control based on a data table is performed on the main throttle valve. When the load is higher than a second predetermined load higher than the first predetermined load, an opening degree of the main throttle valve is brought to a fully-open opening degree, and each of an exhaust bypass valve and an air supply bypass valve is controlled to allow pressure inside an intake manifold to be adjusted to a target value appropriate to the load.
