Abstract: An exemplary engine is a V-type engine including a first bank and a second bank arranged side by side in a left-right direction, the engine including: a first cooling liquid passage and a second cooling liquid passage disposed between the first bank and the second bank and extending in a front-rear direction; and an exhaust passage disposed between the first bank and the second bank and extending in a front-rear direction and disposed below the first cooling liquid passage and the second cooling liquid passage.

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.

Abstract: The object of the present invention is to provide a compact engine. An engine has a two-stage turbocharger provided with a high-pressure turbocharger and a low-pressure turbocharger. The high-pressure turbocharger and the low-pressure turbocharger are separately disposed on the gear case side and the flywheel side in along direction of a main body respectively. An intake pipe and an exhaust pipe connecting the high-pressure turbocharger with the low-pressure turbocharger are separately and respectively disposed on right side and left side in a transverse direction of the main body.
