摘要： A piston particularly adapted for heavy-duty diesel engine applications is fabricated from separate parts having circumferentially extending joining surfaces that are heated prior to bonding to an elevated temperature sufficient to enable bonding of the joining surfaces, and thereafter the joining surfaces brought into contact with one another and twisted to attain a permanent metallurgical weld at the interface of the joining surfaces. The piston has radially spaced walls which are both welded simultaneously. The weld joints may lie in the same or different planes. Once joined, and while still hot, the parts may be pulled apart slightly to reduce the wall thicknesses at the weld joint.

摘要： A shaft assembly for a barrel internal combustion engine having valves controlling the intake and exhaust of gases during operation of the engine. The shaft assembly includes a drive shaft and a cam shaft. The drive shaft extends longitudinally between opposite first and second ends along a rotational axis. The cam shaft has cam lobes for actuating the valves of the engine. The cam shaft is coupled in a spline arrangement with an end of the drive shaft for rotation therewith about the rotational axis. The cam shaft is substantially coaxial with the drive shaft.

摘要： A barrel internal combustion engine includes a plurality of pistons, a drive shaft, a cam plate and an oil pump. The plurality of pistons is slidably coupled to a plurality of cylinders for reciprocal movement along axes generally parallel with a central axis. The drive shaft is rotatable about the central axis. The cam plate is coupled to the drive shaft for rotation therewith. The cam plate is operatively coupled to the pistons to cause rotation of the drive shaft about the central axis in response to the reciprocal movement of the pistons. The oil pump has a rotatable input member coupled coaxially with the drive shaft for rotation therewith about the central axis for actuating the oil pump. The oil pump may be provided in the form of a geroter.

摘要： A piston particularly adapted for heavy-duty diesel engine applications is fabricated from a separate head portion and base portion having circumferentially extending joining surfaces that are heated prior to bonding to an elevated temperature sufficient to enable bonding of the joining surfaces, and thereafter the joining surfaces brought into contact with one another and twisted to attain a permanent metallurgical weld at the interface of the joining surfaces. The head portion has an eccentric combustion bowl and crown. The joined head portion and base portion together form a monobloc piston having a closed gallery which is adapted to receive a cooling fluid, such as oil. The combustion bowl has a substantially uniform bowl sidewall thickness. The piston and method are particularly adopted for use with steel alloys and other high temperature metal alloys.

摘要： A multi-axially forged mono-bloc piston includes a lower crown part forged of steel and including a pair of pin bosses and an integral skirt formed as one piece with the pin bosses 20. The lower crown part is friction welded to an upper crown part to form at least one closed oil gallery within the piston head. The lower crown part is forged in the longitudinal direction of the piston as well as laterally to impart longitudinal and laterally forged features of the piston. The laterally forged features may comprise undercut recesses formed in the piston skirt to reduce material in the overall piston structure. The lateral forging may also result in the piston skirt portion being discoupled from the piston head by laterally forged slots formed in the lower crown part 14 between the skirt and head.
