Abstract: A method of additive manufacturing an object by applying metal layerwise on a base with an application device successively aligned with different processing zones in relation to the base includes locally applying liquid metal in a processing zone. The liquid metal solidifies in the processing zone and precise adjustment of local material properties of the object are controlled by influencing or controlling temperature development as a function of time of the solidified metal with at least one thermal influencing device aligned with the processing zone and fixed relative to the application device. The thermal influencing device is at least one of a heating device and a cooling device.

Abstract: A manufacturing installation for the additive manufacturing of components, each provided with at least one material overhang, has at least one building platform on which the particular component can at least partially be additively manufactured. In order to reduce the material consumption and the time to produce additively manufactured components, the manufacturing installation has at least one preferably electrically controllable support device with at least one movable support arm for the at least temporary holding of at least one support element, arranged on the support arm, during the additive manufacture of the particular component above the building platform.

Abstract: A hydrogen fuel cell vehicle system and method inhibit formation of black ice on road surfaces at low temperatures as a result of exhaust water by treating the exhaust water prior to discharge with a deicing or antifreeze substance to lower the freezing point of the water. A metering device may meter a deicing or antifreeze substance, such as sodium chloride, calcium chloride, urea, or the like to be dissolved in the exhaust water that is produced during the production of energy. The vehicle may include a bypass valve that selectively bypasses the water treatment system when ambient conditions are not conducive to ice formation. The bypass valve is operated to direct exhaust flow to a condenser and water treatment system when ambient conditions are favorable to ice formation, with the deicing or antifreeze substance metered based on current or predicted ambient or road surface conditions.

The cylinder bore is configured to receive a piston for reciprocating movement therein and has a pressure side and a counter-pressure side. The cylinder bore includes a bore surface having a first roughness value in a first longitudinal region on the pressure side and a second roughness value different from the first roughness value in the first longitudinal region on the counter-pressure side.

Abstract: Methods and systems are provided for an internal combustion engine having an oil circuit. In one example, a system may include a rising oil line from a block to a cylinder head of an engine; a main oil line in the head; and an oil siphon system including a reservoir positioned between, and having at least one portion at a lower elevation than both, a section the rising line and a section of the main oil line so that oil flows into, and remains in, the reservoir when the engine is shut-off. In this way, the design of the oil circuit may be used to improve oil supply to engine components while minimizing delays in oil supply during engine startup.
