摘要： A method of laser spot welding a workpiece stack-up(10) that includes at least two overlapping steel workpieces(12,14), at least one of which includes a surface coating(40), is disclosed. The method includes directing a laser beam(24) at the top surface(20) of the workpiece stack-up(10) to create a molten steel weld pool(90) that penetrates into the stack-up(10). The molten steel weld pool(90) is then grown to penetrate further into the stack-up(10) by increasing an irradiance of the laser beam(24) while reducing the projected sectional area(86) of the laser beam(24) at a plane of the top surface(20) of the workpiece stack-up(10). Increasing the irradiance of the laser beam(24) may be accomplished by moving a focal point(62) of the laser beam(24) closer to the top surface(20) or by reducing an angle of incidence(82) of the laser beam(24) so as to reduce the eccentricity of the projected sectional area(86) of the laser beam(24).

摘要： A pressure balanced valve for an expander of a Rankine cycle heat recovery system includes a valve body that extends along a longitudinal axis. The valve body includes a valve head and an intermediate flange structure spaced apart from each other along the longitudinal axis. The valve body defines an internal flow channel having at least one output port and at least one inlet port. The at least one output port of the internal flow channel is defined by a cylinder chamber side of the valve head. The at least one inlet port of the internal flow channel is defined by a valve stem side of the intermediate flange structure. The internal flow channel is operable to communicate fluid pressure between the cylinder chamber side of the valve head and the valve stem side of the intermediate flange structure.

摘要： A method of laser welding a workpiece stack-up (10) that includes at least two overlapping aluminum workpieces (12, 14) comprises advancing a laser beam (24) relative to a plane of a top surface (20) of the workpiece stack-up (10) and along a spot weld travel pattern (74) that includes one or more nonlinear inner weld paths and an outer peripheral weld path that surrounds the one or more nonlinear inner weld paths. Such advancement of the laser beam (24) along the spot weld travel pattern (74) translates a keyhole (78) and a surrounding molten aluminum weld pool (76) along a corresponding route relative to the top surface (20) of the workpiece stack-up (10). Advancing the laser beam (24) along the spot weld travel pattern (74) forms a weld joint (72), which includes resolidified composite aluminum workpiece material derived from each of the aluminum workpieces (12, 14) penetrated by the surrounding molten aluminum weld pool (76), that fusion welds the aluminum workpieces (12, 14) together.

摘要： An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head mounted to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing a mixture of air and fuel. A crankshaft is arranged in the cylinder block and rotated by an application of combustion force on the piston. An intake valve is operatively connected to the cylinder head and controls delivery of the air to the cylinder for combustion therein. A mechanism provides a constant peak lift of the intake valve over an angle of rotation of the crankshaft that is at least 5 degrees, i.e., an extended dwell at peak lift. A vehicle having such an engine is also disclosed.

A pressurizable tank is disposed on the vehicle to contain a natural gas. A natural gas adsorbent is disposed in the tank. A fuel supply tube is to convey the natural gas to the ICE. A scroll compressor is on the vehicle to receive the natural gas from the tank and to deliver a first mixture of compressed natural gas and an oil to a gas and oil separator. The gas and oil separator is to receive the first mixture of the compressed natural gas and the oil from the scroll compressor and to separate the oil from the compressed natural gas and to deliver the compressed natural gas to the fuel supply tube substantially free from the oil.

摘要： A method of attaching a thermoplastic-based workpiece and a metal workpiece involves the use of a metal reaction coating. The metal reaction coating is applied over a base metal substrate of the metal workpiece such that the metal reaction coating faces and contacts the thermoplastic-based workpiece when the two workpieces are assembled in overlapping fashion. To attach the workpieces at their faying interface, an energy source such as, for example, a laser beam or an electric arc, is directed against the metal workpiece to create a zone of concentrated heat that at least warms up the metal reaction coating and melts a portion of the thermoplastic-based workpiece. Such heated activity at the faying interface promotes interfacial chemical bonding between the thermoplastic-based workpiece and the metal workpiece that contributes to an enhanced attachment between the workpieces.
