Abstract
An engine device in which exhaust pipes and an intake pipe can be mounted highly rigidly by using an upper face corner of a cylinder block in an engine, and a support structure of the exhaust pipes and the intake pipe can be simplified. In an engine device in which a first supercharger and a second supercharger are disposed in series on an exhaust gas discharge path of an engine, the engine device has a structure in which the first supercharger and the second supercharger are disposed to be divided on opposed side faces of the engine, and an upper side exhaust pipe between the engine and the first supercharger, a lower side exhaust pipe between the first supercharger and the second supercharger, and an intake pipe between the first supercharger and the second supercharger extend to be substantially flush with one another at a head-cover disposed-height of an upper face of the engine.
