Abstract: Methods and systems are provided for a piston. In one example, system may comprise a piston comprising a chamber in which a piston bowl may actuated independent of an oscillation of the piston. The chamber may receive a hydraulic fluid in order to adjust a position of the piston bowl within the chamber, thereby adjusting a compression ratio of a combustion chamber in which the piston may oscillate.

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: Methods and systems are provided for an exhaust-gas aftertreatment device. In one example, an exhaust-gas aftertreatment device comprises a housing with a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, wherein the first catalytic converter is not concentric with the first can.

Abstract: At least one coated valve seat region has at least one first layer and a second layer, the second layer is arranged on the first layer, and the first layer and the second layer are different. The first layer and the second layer are each formed by a local thermal deposition welding method. In the case of a cylinder head of an internal combustion engine, a valve seat region is formed by depositing a first layer on a substrate material of the valve seat by a laser deposition welding method in one method step and, in a subsequent method step, depositing a second layer on the first layer by a laser deposition welding method. The second layer contains a material which exerts a material hardening effect.

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.

Abstract: The disclosure relates to a control valve for a medium circuit of an internal combustion engine, in particular to a thermostat of a coolant circuit of the internal combustion engine. The control valve includes a valve housing, an expansible material element arranged in a valve body, an energy accumulator having an abutment element, a valve seat, and at least one locking element arranged on the abutment element, each locking element having a counter-latching face. The control valve has a first position wherein the counter-latching face of each locking element is in a non-positive connection with a corresponding latching face of the valve housing in order to force the control valve into a mechanically blocked, forced-open position, the latching face being formed by means of an opening edge in the valve housing. This position may enable a quick and reliable initial filling or refilling of the coolant circuit.
