Abstract:
1. A method of operating a stationary internal combustion machine, said method comprising: regulating the internal combustion machine to maintain a substantially constant engine regulating value by actuating at least two adjusting members including a first adjusting member comprising a compressor device having a variable compressor geometry for compressing gas fed to the internal combustion machine, and a second adjusting member comprising a throttle device connected downstream of the compressor device and configured to vary an amount of compressed gas fed to the internal combustion machine; and when the engine regulating value deviates from a reference value, altering the amount of compressed gas fed to the internal combustion machine to re-set the engine regulating value to the reference value by: actuating the throttle device; and varying a geometry of the compressor device; wherein said varying of the geometry of the compressor device in a first load range is one of (i) delayed with respect to said actuating of the throttle device; (ii) slower than said actuating of the throttle device; and (iii) both delayed with respect to said actuating of the throttle device and slower than said actuating of the throttle device.
