摘要： A rocker housing is configured to enclose a rocker shaft and rocker arms connected to push rods that protrude from a cylinder head of an internal combustion engine. The rocker housing comprises a sidewall configured to enclose the rocker shaft and a top wall extending laterally from an upper portion of the sidewall so as to extend over the rocker arms. The rocker housing further comprises an aperture configured to accommodate a fuel injector or a fuel supply pipe for supplying fuel to a fuel injector of the internal combustion engine. The rocker housing further comprises a fuel return channel extending within at least a part of the sidewall. The fuel return channel comprises an inlet at the interior surface of the sidewall configured to receive excess fuel from the injector; an outlet at an exterior surface of the sidewall configured to output the excess fuel, wherein the outlet is laterally offset from the inlet; and an interior passage extending between the inlet and the outlet. The interior passage is formed integrally in the sidewall of the rocker housing between the interior surface of the sidewall and the exterior surface of the sidewall. The interior passage has a minor component in a direction between the interior surface and the exterior surface of the sidewall and has a major component in a direction of lateral offset between the inlet and the outlet.

摘要： A plastic molded article includes a base having a main surface, a first tubular portion protruding from the main surface, a second tubular portion protruding from the main surface and having an inner diameter smaller than that of the first tubular portion, and a pair of ribs that protrudes from the main surface and connects an outer circumferential surface of the first tubular portion and an outer circumferential surface of the second tubular portion to each other. The base, the first tubular portion, the second tubular portion, and the ribs are integrally molded of plastic. The ribs are located on opposite sides of an imaginary plane that includes a central axis of the first tubular portion and a central axis of the second tubular portion.

摘要： An oil filter layout structure for an internal combustion engine for a motorcycle. An exhaust pipe connected to an exhaust port extends rearwardly beneath the internal combustion engine along a longitudinal direction of the motorcycle. An oil pan is disposed below the internal combustion engine, the oil pan having one of left and right side walls spaced along a transverse direction of the motorcycle. The one side wall is inclined downwardly toward a center of the motorcycle. The exhaust pipe is disposed closely to the side wall. An oil filter is mounted on the internal combustion engine and disposed below the internal combustion engine in overlapping relation to the oil pan as viewed in side elevation, near the other of the left and right side walls of the oil pan.

摘要： An exhaust valve assembly for use in an exhaust system includes a body region and an auxiliary region. The body region has first and second ends and defines a longitudinal axis defined between the ends. The body region has an interior surface terminating at the ends and defines a flow path along the axis and an opening. The auxiliary region is coupled to the body region about the opening. The auxiliary region has at least one wall that defines a space in communication with the opening outside the flow path. The exhaust valve assembly further includes a shaft coupled to the wall of the auxiliary region and a vane coupled to the shaft. The vane is movable between an open position with the vane disposed entirely within the auxiliary region and a closed position with at least a portion of the vane disposed in the body region intersecting the axis.

摘要： An internal combustion engine having two cylinders, which are arranged in “V” configuration and accommodate respective pistons, and a first balancing body, which is fixed to a crankshaft at a first piston so that the first order reciprocating inertial forces of the first piston lie on a first straight line forming a first inclination angle which is not zero with the first cylinder; the combination of an angle between the cylinders with the first inclination angle is such that the first straight line on which the first order reciprocating inertial forces generated by the first piston lies is parallel to a second straight line on which the first order reciprocating inertial forces generated by the reciprocating motion of a second piston lie.

摘要： A dual link internal combustion engine, as viewed in a crank axial direction where a crankshaft rotates clockwise, has a following relative configuration. A piston pin center axis is offset to a right side of a piston center line extending through a center of a piston crest surface of a piston. A movement trajectory of a link coupling center of first and second links is positioned to a left side of a piston reciprocation line. A piston center of gravity is positioned to the left side. An average value of a distance in the cylinder axial direction to individual points of the piston crest surface from a reference plane passing through the piston pin center axis and orthogonal to the cylinder axial direction in an area to the left side is greater than an average value of the distance in an area to the right side.

摘要： A four-cycle internal combustion engine has a bellows leaf spring working in a compression mode or a tension mode. The leaf spring is connected to a crankshaft and forms a movable portion of a bellows chamber that receives exhaust gases from an engine cylinder. As the exhaust gases transfer from the cylinder to the bellows chamber, the gases push on the leaf spring thereby transferring energy to the crankshaft.
