Control of the supercharging pressure of a turbocharger for an internal combustion engine

Abstract

Abstract The charging pressure control uses an operating element for controlling a bypass valve across the turbocharger and/or altering the geometry of the turbocharger turbine, which is adjusted in dependence on the detected engine revs. In a first load range, the required charging pressure (SW) for controlling the setting element is read from a characteristic field (7) and in a second load range the charging pressure is provided by a regulator (15) of the control, with pre- control via the required charging pressure provided by the characteristic field.
