An engine including a common rail attached to one side portion of a cylinder block that pivotally supports a crankshaft in a rotatable manner, the one side portion extending along a crankshaft center, and the common rail being configured to supply a fuel to the engine. A flywheel housing that accommodates a flywheel that is rotated integrally with the crankshaft is disposed in one side portion out of opposite side portions of the cylinder block intersecting the one side portion. One end portion of the common rail is disposed above the flywheel housing.

An engine device including: an EGR device configured to circulate, as EGR gas, a portion of exhaust gas exhausted from an exhaust manifold manifold to an intake manifold; and an EGR cooler configured to cool EGR gas and supply the EGR gas to the EGR device. The EGR cooler includes a heat exchanger and a pair of flange portions. 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 engine device including a cylinder block having one side portion to which a flywheel that is rotated integrally with a crankshaft is disposed. The engine device is provided with a starter that transmits a rotational force to the flywheel at a time of engine start. A flywheel housing, which accommodates the flywheel and includes a starter attachment pedestal for attaching the starter, is attached to the one side portion of the cylinder block. The starter is disposed inner side of the engine than a portion of the flywheel housing, the portion being located outermost in the engine with respect to a direction that is perpendicular to a direction along a crankshaft center and that is parallel to the cylinder head joining surface of the cylinder block.

An engine (1) of a vehicle powertrain unit (P) includes: an electric exhaust S-VT (27) that is mounted on one end of an exhaust camshaft (26) and changes a rotational phase of the exhaust camshaft; and an EGR device (60) that is provided outside an engine body (10) and connects an intake passage (30) and an exhaust passage (50) together. The EGR device is located closer to a cylinder block (13) than the electric exhaust S-VT in a direction from a cylinder head (14) to the cylinder block, and is arranged so that at least a part of the EGR device and the electric exhaust S-VT overlap with each other when viewed in the direction from the cylinder head to the cylinder block.

An engine apparatus includes an engine, an exhaust gas purification device, an outlet side bracket, and an inlet side bracket. The exhaust gas purification device is mounted above a cylinder head to extend along an axis of an output shaft of the engine. The inlet side bracket is configured to couple an exhaust gas inlet side of the exhaust gas purification device to the cylinder head. The inlet side bracket includes a first bracket, a second bracket, and a third bracket. The first bracket is configured to be secured to a surface of the cylinder head intersecting the axis of the output shaft and includes a wide width. The second bracket includes a proximal end portion and a distal end portion. The third bracket is configured to be coupled to an end surface of the exhaust gas purification device and the distal end portion of the second bracket.
