An engine device including, a cylinder block (6) having one side portion to which a flywheel that is rotated integrally with a crankshaft (5) is disposed. The engine device is provided with a starter (20) that transmits a rotational force to the flywheel at a time of engine start. A flywheel housing (7), which accommodates the flywheel and includes a starter attachment pedestal for attaching the starter (20), is attached to the one side portion of the cylinder block (6). The starter (20) is disposed inner side of the engine than a portion of the flywheel housing (7), the portion being located outermost in the engine with respect to a direction that is perpendicular to a direction along a crankshaft center (300) and that is parallel to the cylinder head joining surface (341) of the cylinder block (6).

An engine device (1) including: an EGR device (24) configured to circulate, as EGR gas, a portion of exhaust gas exhausted from an exhaust manifold (3) to an intake manifold (4); and an EGR cooler (27) configured to cool EGR gas and supply the EGR gas to the EGR device. The EGR cooler includes a heat exchanger (91) and a pair of flange portions (92, 93). The heat exchanger has a coolant passage and an EGR gas fluid passage alternately stacked. The flange portions are disposed on the heat exchanger. An outlet of the coolant is disposed in one of the flange portions, while an inlet of the coolant is disposed in the other flange portion. An inlet of the EGR gas is disposed in one of the flange portions, while an outlet of the EGR gas is disposed in the other flange portion.

An end plate for a vehicle includes an upper end plate, a lower end plate, and a cover that covers a gap between a lower end edge of the upper end plate and an upper end edge of the lower end plate. The vehicle includes an engine and a housing. The engine is fastened to the housing through the end plate. A first stepped portion having a pair of a first flat surface and a second flat surface intersecting with the first flat surface is provided on the engine side of the cover. The first flat surface is inclined downward with respect to a horizontal plane as the first flat surface is directed toward the engine side.

A transverse engine adjacent to a drive shaft includes an engine body having a crankshaft, a first pipe connected to the engine body and running such that an engine coolant flows therethrough, and an accessory drive system. The accessory drive system includes an endless outer belt wound between a crankshaft pulley and an alternator drive pulley. A portion of the first pipe forms a water protector located between the drive shaft and the outer belt and overlapping with the outer belt as viewed from the front or rear of the vehicle.

A V-type engine includes an engine body including a crankcase configured to rotatably support a crankshaft, and a first and second cylinder banks extending from the crankcase, an exhaust collecting pipe connected to the first and second cylinder banks, a catalyst accommodated in the exhaust collecting pipe, and a muffler detachably connected to the exhaust collecting pipe, wherein when viewed in an axial direction of the crankshaft, the catalyst is arranged within an area between axial lines of the first and second cylinder banks.

A transmission assembly structure includes an engine-side joining surface, a transmission-side joining surface, which is joined to the engine-side joining surface, an engine component which is provided on an outside of the engine-side joining surface in a radial direction in the flywheel housing and protrudes toward the transmission side, a guide member which is provided on the engine-side joining surface or in the vicinity of the engine-side joining surface of the flywheel housing and in a vicinity of the engine component and which protrudes toward the transmission side further than the engine component, and a guide hole, which is provided on the transmission-side joining surface of the transmission housing or in the vicinity of the transmission-side joining surface and into which the guide member is inserted.

An exhaust device for a saddle-type vehicle having a pipe section with respect to a vehicle body and housing a catalyzer therein, and a muffler connected to a rear end of the pipe section includes an upstream oxygen sensor positioned upstream of the catalyzer and a downstream oxygen sensor positioned downstream of the catalyzer. The downstream oxygen sensor is disposed in either a position overlapping a main stand for supporting a motorcycle as viewed from below the vehicle body when the main stand is stored, or a position overlapping a stand receiver for abutting against the main stand as viewed from below the vehicle body when the main stand is stored. The pipe section includes a larger-diameter portion having an increased diameter for housing the catalyzer therein.
