Engine apparatus
An apparatus includes an exhaust gas purification device configured to be coupled to a cylinder head of an engine via a bracket, the exhaust gas purification device defined by a housing including a body portion, a first end portion, and a second end portion, the body portion interposed between the first end portion and the second end portion, the first end portion configured to be coupled to the bracket.
V-type engine, outboard motor, and ship
A V-type engine, an outboard motor, and a ship capable of restricting exposure of a catalyst to water. The engine includes cylinders where pistons operate are arranged in a V-shape, a crankshaft driven by driving of the pistons is disposed vertically, and exhaust pipes communicating with exhaust openings in the respective banks of a cylinder head and a catalyst holder that holds a catalyst in a merge portion where the exhaust pipes are merged in a site located on an upper side of the banks are included.

Engine device
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.

Balancer device for internal combustion engine and its assembly method
A balancer device for an internal combustion engine includes upper and lower housings made of aluminum alloy. The upper housing includes a leg part fixed to the engine. The lower housing is coupled to the upper housing by tightening bolts. A pair of balancer shafts are rotatably supported by the upper and lower housings. A positioning pin is disposed at a distal end portion of the leg part for positioning the upper housing with respect to the engine by positional correspondence to a positioning hole of the engine when the tightening bolts are tightened. The leg part is inclined outwardly with respect to a body of the upper housing such that a distal end of the positioning pin is located outside of a proximal end of the leg part with respect to the body of the upper housing when the tightening bolts are loosened.
Internal combustion engine and separator structure thereof
An internal combustion engine includes a cylinder block, an auxiliary machinery attachment member arranged at a side wall of the cylinder block, the auxiliary machinery attachment member to which an auxiliary machine is attached, and a separator portion disposed in a void between the cylinder block and the auxiliary machinery attachment member, the separator portion being provided as a separate member from the cylinder block and the auxiliary machinery attachment member to perform gas-liquid separation on blow-by gas.

ENGINE
An engine includes a crank shaft inside a crankcase and an oil pan and penetrates the crankcase and the oil pan in an up-down direction. An oil pump and an oil strainer are provided inside the oil pan. The oil pump is coaxial with the crank shaft and is driven by the crank shaft. The crank shaft includes a first region and a second region respectively supported pivotably by a plate-shaped support and the crankcase. The support is provided in the crankcase such a that both surfaces of the support are covered by the crankcase and the oil pan and allows communication between the crankcase and the oil pan.
