Abstract
A method for determining a basic boost pressure of a gas conducting system of an internal combustion engine with a turbocharger that has a compressor, a turbine, a shaft connecting the compressor and the turbine, and a turbocharger actuator for varying a flow velocity through the turbine or a pressure ratio across the turbine. The method comprises calculation of an exhaust gas back pressure at the open turbocharger actuator position, wherein the flow velocity through the turbine or the pressure ratio across the turbine is minimal in the open turbocharger actuator position, and determination of the basic boost pressure as a function of the calculated exhaust gas back pressure at the open turbocharger actuator position. An engine controller for carrying out a method for determining a basic boost pressure is also provided.
