Abstract: An exhaust device is configured to flow exhaust gas to be discharged from each of cylinders of an engine body. The engine body includes the cylinders arrayed in a row. The exhaust device includes an exhaust passage extending in the cylinder array direction; an exhaust outlet portion connected to an end of the exhaust passage in the cylinder array direction; a supercharger disposed at an end of the engine body in the cylinder array direction, and connected to the exhaust outlet portion; a lateral exhaust pipe connected to the supercharger, and disposed along a lateral surface of the engine body in the cylinder array direction; and an exhaust gas purification device disposed midway in the lateral exhaust pipe.

Abstract: A supercharging device for an engine includes an electric supercharger which supercharges intake air, an intercooler which cools intake air discharged from the electric supercharger; and an intake manifold which is disposed substantially horizontally, and is configured to communicate between a downstream end of the intercooler in an intake air flow direction, and intake ports. The downstream end of the intercooler is located on a lower end of the intercooler. The downstream end of the intercooler is disposed substantially at the same height as an upstream end of the intake ports. The electric supercharger is disposed below the intercooler along a surface of the engine on an intake side where the intake ports are opened.
