Abstract: An exhaust port liner, which may include a superalloy and may be manufactured by an additive manufacturing process, includes a monolithic structure including an outlet disposed an angle relative to an inlet, and a sidewall defining a cavity to provide enhanced thermal performance in reciprocating internal combustion engines. A cylinder head of an internal combustion engine may include a cylinder head frame, and the exhaust port liner may be disposed proximate the frame inner mounting surface, with an outer surface of the exhaust port liner conforming to an inner mounting surface of the cylinder head frame.

Abstract: An internal-combustion engine, which is suitable for being installed in a motor vehicle, has auxiliaries including a generator and a water pump which are arranged on an exterior side of a housing structure of the internal-combustion engine. In order to construct the auxiliaries in an easily mountable manner and to advantageously accommodate them on the housing structure of the internal-combustion engine, the generator and the water pump form a constructional unit which is connected with the housing structure of the internal-combustion engine.

Abstract: A pumping device suitable for a lubricant of an internal-combustion engine, for example, of the piston construction, includes a pressure pump device and a suction pump device, which suction pump device has several suction pumps which are connected with suction devices of the internal-combustion engine. In order to improve the pumping device with respect to its function and construction, adjacent suction pumps are constructed as gear pumps connected to the suction device, the gears of the gear pumps being arranged coaxial with respect to one another and being connected with one another by a driving device.

Abstract: A monofil fabric for use as a perpendicular trickle wall in exchange columns wherein gas and liquid are contacted with one another, which comprises wires disposed in the same horizontal plane which wires are positioned contiguously to one another in groups, the spacing between a group of contiguously positioned wires and the next wire running in the same general direction being at least equivalent to the diameter of a wire of said group.
