ENGINE DEVICE

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. 1. An engine device comprising:at least one cylinder;an intake manifold configured to supply air into the at least one cylinder;an exhaust manifold configured to discharge exhaust gas from the at least one cylinder;at least one main fuel injection valve configured to inject liquid fuel into the at least one cylinder to cause combustion of the liquid fuel;at least one gas injector configured to mix gas fuel with the air supplied by the intake manifold;a supercharger comprising a compressor and configured to compress air through a use of the exhaust gas from the exhaust manifold;an intercooler configured to cool compressed air resulting from the compression by the supercharger and supply resultant cooled air to the intake manifold;a main throttle valve disposed at a portion where an outlet of the supercharger and an inlet of the intercooler are coupled to each other;an exhaust bypass flow path configured to couple an outlet of the exhaust manifold to an exhaust outlet of the supercharger;an exhaust bypass valve disposed in the exhaust bypass flow path;an air supply bypass flow path configured to bypass the compressor of the supercharger; andan air supply bypass valve disposed in the air supply bypass flow path,wherein, when a load on the engine device is lower than a first predetermined load falling within a low ...
