摘要： A turbocharger, with a turbine that includes a turbine housing, turbine inflow housing, a rotor, and a compressor, which has a compressor housing and a rotor coupled to the turbine rotor via a shaft. A bearing housing is arranged between and coupled to the turbine and the compressor housings. The turbine inflow housing has a radially inner, outer and middle walls. The inner wall delimits an exhaust gas flow duct, and a cooling channel between the outer and middle walls. The bearing housing, extends, seen in the axial direction as far as into the region of the inner wall of the turbine inflow housing. A cooling water channel in the bearing housing surrounds the inner wall of the turbine inflow housing in the axial region and the bearing housing extends as far as into the region of the radially inner wall of the turbine inflow housing, radially on the outside.

摘要： A radial compressor having a compressor rotor with blades; a compressor housing, a diffuser having guide vanes. The diffuser delimits a flow duct in radial direction. The guide vanes of have a flow inlet edge, a flow outlet edge, and flow-conducting sides. The guide vanes project into the flow duct that is delimited by the diffuser. The guide vanes merge into a support body subject to forming a curvature region that is defined on the flow side. In each position of the curvature region, i.e. in the region of the flow inlet edge, in the region of the flow outlet edge and in regions between the flow inlet edge and the flow outlet edge a curvature radius that is defined on the flow side is formed in each case.

摘要： A catalyst unit for an exhaust gas catalyst, having a ceramic catalyst body, and a metallic housing which encloses the catalyst body at least in some sections perpendicular to a gas throughflow direction. At least one bearing mat positioned between the catalyst body and the housing perpendicular to the throughflow direction. The catalyst body is retained in the housing via a force-closed press fit with the intermediate arrangement of the or each bearing mat such that, when seen in the throughflow direction of the catalyst body, the press fit between the housing and the catalyst body is formed exclusively at defined axial positions, the housing having groove-like depressions at the defined axial positions for reducing in some sections the inner cross-section of the housing, and the press fit between the housing and the catalyst body being formed exclusively in the region of the groove-like depressions.

摘要： A method for operating an internal combustion engine having a plurality of cylinders includes: measuring, by exhaust gas sensors arranged at an exhaust gas of every cylinder for which cylinder-specific combustion control is carried out, for each respective cylinder, at least one actual combustion value; comparing each respective measured actual combustion value with a reference combustion value to determine at least one cylinder-specific control deviation for every cylinder for which cylinder-specific combustion control is carried out; determining at least one cylinder-specific control variable for every cylinder for which cylinder-specific combustion control is carried out based on the cylinder-specific control deviation or on every cylinder-specific control deviation; and operating each cylinder for which cylinder-specific combustion control is carried out based on the respective cylinder-specific control variable to bring the respective actual combustion value closer to the respective reference combustion value and minimize the respective control deviation.

摘要： An impeller for a rotor of a turbomachine includes: a wheel disc mounted on the rotor, the wheel disc having plural grooves arranged along a circumference of the wheel disc and extending in the thickness direction of the wheel disc. A toothed profile is formed on two sides of each groove. A plurality of impeller blades each have one root with two sides on each of which one toothed profile is formed. Each blade is inserted into a groove so as to form a blade-groove combination with the toothed profiles of the root and of the groove in engagement. Each combination having a fixing device that fixes the blade in the groove in the thickness direction and in the radial direction of the wheel disc. Each fixing device has a recess movably received in the groove base.

摘要： A method for operating a cooling system of a ship, having a sea water part system with a sea water pump (14a, 14b) and at least one first cooling water circuit. The first cooling water circuit includes a bypass in a heat exchanger coupling the sea water part system and the first cooling water circuit and a control valve. A position of the control valve determines a cooling water proportion of the first cooling water circuit that is conducted via the heat exchanger and a cooling water proportion of the first cooling water circuit that is conducted via the bypass. The position of the control valve is controlled such that an advance cooling water temperature corresponds to a set point value. The rotational speed of the sea water pump is controlled based on the position of the control valve.

摘要： An end plate for an electric machine includes: a bearing receptacle in which a magnetic bearing which is configured for rotatably mounting a rotor of the electric machine can be accommodated; and a radially outwardly pointing circumferential contour on which a number of at least three supporting elements are provided, which supporting elements each protrude radially beyond the circumferential contour by a determined protruding amount, with the result that the supporting elements define a discontinuous external circumferential contour of the end plate. The respective protruding amounts of the support elements are dimensioned such that the end plate can be fitted in by making a center of the magnetic bearing correspond to at least one of a geometric longitudinal axis of the electric machine and a magnetic longitudinal axis of the electric machine.

摘要： A radial compressor for a compressor arrangement comprising the radial compressor and an axial compressor includes an inlet flow channel bounded by a radially inner hub contour and a radially outer housing contour, in which inlet guide blades are arranged. Via the inlet flow channel a medium to be compressed is supplied to an impeller having moving blades. The inlet flow channel runs diagonally to an axis of rotation of the impeller.
