摘要： An oil separation device of an internal combustion engine includes a gas liquid separation chamber defined by a head cover of the engine, a gas introduction passage connected to a first end of the gas liquid separation chamber at an angle to the first direction, a gas inlet formed in an end of the gas introduction passage remote from the gas liquid separation chamber, and a gas outlet formed in a second end of the gas liquid separation chamber. Oil splashed from a valve actuating chamber of the engine is prevented from entering the oil separation device, and oil mist can be effectively separated from blow by gas.

摘要： A rocker arm assembly for an engine is configured to fit about a pivot shaft that extends along a central axis. The assembly includes an intermediate shaft configured to be rotatably disposed about the pivot shaft. A cam-side arm is pivotable about the central axis and is configured to be driven by a cam. A valve-side arm is pivotable about the central axis and relative to the cam-side arm, and is configured to convert rotation of the rocker arm assembly about the central axis into operation of an engine valve. An annular compressible fluid chamber is disposed between the intermediate shaft and the valve-side arm. When the cam-side arm and the intermediate shaft are engaged, pivoting of the cam-side arm compresses fluid within the chamber, causing corresponding pivoting of the valve-side arm and operation of the valve. The fluid provides hydraulic lash adjustment.

摘要： An engine, including a crankcase, a cylinder body extending upward from the crankcase, a cylinder head coupled to an upper portion of the cylinder body, a cylinder head cover coupled to an upper portion of the cylinder head, and a gasket disposed between the cylinder head and the cylinder head cover. The gasket includes a projection that projects along directions from an inner wall of the cylinder head and from the cylinder head cover toward a camshaft. The projection is located in a cam chain chamber, which is formed in the engine along the cylinder body, the cylinder head and the cylinder head cover, and a cam chamber formed in the engine along the cylinder head and the cylinder head cover. The projection has an oil supply portion disposed in the cam chain chamber and above a cam chain guide guiding a cam chain.

摘要： A rocker arm assembly for translating force between an intermediate member in communication with a camshaft of an internal combustion engine and a valve supported in a cylinder head of the engine. The rocker arm assembly includes a tube member and an arm. The tube member has first and second ends, a substantially cylindrical inner surface, and a tapered outer surface. The arm has a body extending between a pad for engaging the valve of the engine, and a socket for engaging the intermediate member of the engine. The body also has a tapered bore disposed between the pad and the socket. The tapered bore of the body of the arm cooperates with the tapered outer surface of the tube member so as to define a lock for constraining the arm to the tube member at a predetermined position between the first end and the second end.

摘要： An oil passage structure of a dry sump engine includes an oil recovery passage, at least one first communicating hole, and a first oil suction passage. The oil recovery passage extends in a direction in which a cylinder bank extends and is disposed so that at least part of the oil recovery passage is located outward of an external lower end portion of a valve gear chamber of a cylinder head along a junction between a side wall portion of the cylinder head and a bottom surface of the valve gear chamber in a state where the dry sump engine is mounted on a vehicle in an inclined manner. The at least one first communicating hole is provided in the side wall portion so as to connect the valve gear chamber of the cylinder head and the oil recovery passage.

摘要： A cover has an aperture through which an accessory gains access to the interior side of the cover and a cavity. The accessory may be any kind of sensor or actuator. To secure the accessory to the cover, an adapter coupled to the cover is provided. In one example, the adapter has a cylindrical connection section that is spin welded into place in the cavity. In another example, the adapter has self-tapping threads that engage with the surface surrounding the cavity. The adapter also has tabs extending outwardly from the cover, the tabs having a proximate section and an engagement section. The accessory has a retaining orifice that couples with the tabs in a snap-fit relationship to secure the accessory to the cover.
