Abstract: An accessory mounting structure for an engine includes an engine body, and a transmission disposed on an end of the engine body in the cylinder array direction and to which output of the engine is transmitted via a crankshaft of the engine body. When the output side of the crankshaft with respect to the transmission in the cylinder array direction is defined as a rear side, and the side of the crankshaft opposite to the rear side is defined as a front side, a fuel pump configured to feed fuel to an injector, and a starter configured to rotate the crankshaft at an engine start time are disposed on a rear end portion of an intake manifold mounting surface of the engine body. When the engine is viewed from the cylinder array direction, the starter projects outwardly with respect to the fuel pump in the engine width direction.

Abstract: Substances in external EGR gas are smoothly guided to a combustion chamber. An intake passage includes: a main intake passage including intake ports and communicating with a combustion chamber and having a supercharger interposed in the main intake passage; and a bypass passage branching off from the main intake passage upstream of the supercharger, and connected downstream of the supercharger; a flow rage adjustment valve changing a cross-sectional flow area of the bypass passage. The bypass passage is provided above the main intake passage, and includes an upper passage to which an EGR passage is connected.
