  "textContent": "The method involves regulating charging pressure depending on ambient air density by determining actual ambient temperature, ambient pressure, induced air mass and charging pressure at defined time intervals. The compressor inlet pressure and temperature are determined from these readings. The compressor air mass throughput is corrected for standard conditions, and maximum permissible charging pressure is derived and compared with actual pressure, and the charging pressure is regulated accordingly. The method involves regulating the charging pressure depending on the density of the ambient air by determining actual ambient temperature, ambient pressure, induced air mass and charging pressure at defined time intervals, deriving the pressure (pVE) and temperature (TVE) at the compressor (5) inlet, deriving the air mass throughput of the compressor corrected for standard conditions, deriving the maximum permissible charging pressure from the compressor characteristic, comparing it with the actual pressure (pList) and regulating the charging pressure accordingly. Independent claims are also included for an internal combustion engine with an exhaust gas turbocharger and an engine controller for an internal combustion engine with an exhaust gas turbocharger.",
