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: Methods and systems are provided for a cooling arrangement. In one example, the cooling arrangement comprises flowing coolant to only an upper portion of a cylinder head during a cold-start. The cooling arrangement comprises flowing coolant to a cylinder block, a lower portion of the cylinder-head, and the upper portion of the cylinder head outside of the cold-start.

Abstract: Systems are provided for an integrated exhaust manifold that may be used in a variety of engine systems. In one example, an integrated exhaust manifold may include a central axis running from an inlet end to an outlet end of the integrated exhaust manifold and two exhaust outlets arranged at the outlet end and coupled to a common collecting line, the two exhaust outlets symmetrically positioned across the central axis and having a same diameter, where each exhaust outlet of the two exhaust outlets has a passage axis arranged parallel to the central axis. A first exhaust outlet of the two exhaust outlets may be permanently blocked and a second exhaust outlet of the two exhaust outlets may be coupled to an exhaust system of an engine system.

Abstract: Methods and systems are provided for cleaning a water-cooled charge-air cooler. In one example, a method may include condensing water present in the supplied charge-air and exhaust gas which may exist in gaseous and droplet form, and purging the condensate along with the exhaust gas. A system for carrying out the above mentioned method is also provided.

Abstract: A system and method is provided for an at least partially variable valve drive in an internal combustion engine. In one example, the at least partially variable valve drive comprises a hydraulically adjustable actuating device which may be charged with pressurized oil via an oil pressure line which branches off from an oil circuit.

Abstract: A system and methods are described for a turbocharged engine, comprising powering the engine using a first operating cylinder, supplementing the power using a second switchable cylinder, deactivating the second switchable cylinder responsive to a load below a first threshold, and closing a first shut-off valve downstream of a compressor during the partial deactivation to prevent a first turbocharger from imparting a delivery action into a second compressor during the partial deactivation. Embodiments are further described wherein a bypass line in a second exhaust line further serves as a short-circuit line to prevent the second compressor from imparting a delivery action against the closed first shut-off valve. A variable valve timing is then included to further optimize the combustion process during the partial deactivation.

Coupling the valve rocker arm to the cam follower of the first cam enables a two-stroke mode and coupling the valve rocker arm to the cam follower of the second cam enables a four-stroke mode.
