Abstract

An engine is provided with an engine body, a crankshaft, a cooling fan, an exhaust manifold, a supercharger, an ATD that purifies exhaust gas, and a second exhaust pipe. When the height direction of the engine is defined as a first direction, the crankshaft extends in a second direction vertical to the first direction. The cooling fan is disposed on one side of the engine body in the second direction. The supercharger is driven by the exhaust gas from the exhaust manifold. The second exhaust pipe connects the supercharger and the ATD. The ATD is disposed in an attitude in which the longitudinal direction thereof is parallel to the second direction. The second exhaust pipe is connected to the cooling fan side of the ATD in the second direction. The second exhaust pipe is disposed so as to pass laterally with respect to the exhaust manifold and below the supercharger.
