  • Publication number: 20050188696
    Abstract: A method for operating an internal combustion engine having at least two exhaust-gas turbochargers, which allows the synchronous operation of the two exhaust-gas turbochargers to be reliably set (adjusted). For each of the at least two exhaust-gas turbochargers, an actuator for controlling the boost pressure produced by the compressors of the at least two exhaust-gas turbochargers is controlled by a separate control signal. At least one of the control signals is corrected in an open-loop-controlled manner for the purpose of synchronizing the at least two exhaust-gas turbochargers.

  • Publication number: 20050160732
    Abstract: A method for operating an internal combustion engine having an exhaust-gas turbocharger allows for an optimized charge air pressure buildup. For this purpose, an actuator for influencing the charge air pressure generated by a compressor of the exhaust-gas turbocharger is triggered. A characteristic of a trigger signal of the actuator is specified as a function of time.
