  • Patent number: 10119419
    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.

  • Publication number: 20160326955
    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.

  • Patent number: 6600408
    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.
