Abstract: The invention relates to a method for determining bearing play of exhaust-gas-turbocharger friction bearings comprising the following method steps: accelerating the exhaust-gas turbocharger or the body group from standstill to a maximum rotational speed and at the same time registering the vibration acceleration by means of a sensor; determining the constant-tone frequency of the friction bearing at at least one rotational speed; plotting the determined constant-tone frequency in a diagram, in which bearing-play ranges determined experimentally in advance are assigned to constant-tone frequency ranges; and establishing whether or not the determined constant-tone frequency lies in a bearing-play target range.

Abstract: A method for operating a gas turbine (11) having a compressor (12), a turbine (14) and a combustor (13) with a pilot burner group (15a), a rich premix burner group (15b) and a lean premix burner group (15c), under changing composition of the incoming fuel gas (16), includes the steps of: continuously measuring, in real time, the composition of the fuel gas (16); and controlling the operation of the gas turbine (11) and the combustion of the burners (15a-c) by using the real time fuel gas composition measurements.

Abstract: A turbocharger (1) having a turbine housing (2), a compressor housing (3) which has a compressor outlet (20), and a silencer (21) which is arranged on an end region (22) on the compressor outlet (20) and which has a silencer housing (23) in which an insert part (25) is arranged so as to form at least one buffer chamber (24) which is connected via at least one opening (26) to an air-guiding duct (27). The opening (26) has an edge (28) with a radially inner corner (29) which is designed so as not to have a sharp edge.

Abstract: The present invention generally relates to the field of combustion technology related to gas turbines. More in particular, the present invention refers to a method for operating a combustion device. Advantageously, a pulsation protective load shedding is avoided by adjusting the parameter ? in case of too high combustion pulsation levels from the standard operation set point. This implies that the dynamic pulsation control logic is activated in case the high frequency pulsation level exceeds a predetermined threshold value and a control unit adjusts the ?, preferably in a stepwise manner, until acceptable and optimum pulsation levels are reached or a maximum reduction of the ? is performed.

Abstract: A lamp comprises has an optically transmissive enclosure and a base. At least one LED is located in the enclosure and is operable to emit light when energized through an electrical path from the base. A light non-transmissive portion defines a light transmissive portion where the light transmissive portion is illuminated when the at least one LED is energized. The light transmissive portion may define information such as branding information.

Abstract: The invention relates to a compressor (1) of an exhaust-gas turbocharger (ATL), having a compressor housing (3) which has a housing inlet connecting piece (20) and a noise ring (21). The noise ring (21) is arranged in the housing inlet connecting piece (20) and is provided, on its outer circumference (22), with a multiplicity of chambers (23, 24, 23?, 24?).

The knife sectors include grooves and at least three refiner strips, and the knife sectors and refiner strips are structured to form one continuous part. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A device for the targeted transmission of sound from an induction tract of an internal combustion engine in a motor vehicle into the interior of the motor vehicle, comprising a hollow transmission body which communicates with the induction tract on the intake side and which emits sound on the output side into the vehicle interior. In order to improve the sound emission of a device of this type, the invention proposes that the transmission body had a conduit section with a conduit cross-section and a chamber section with a chamber cross-section, whereby the chamber cross-section is larger than the conduit cross-section. The conduit section communicates with the induction tract on the intake side and opens into the intake side of the chamber section. The output side of the chamber section emits the sound into the vehicle interior.
