Abstract

The present application relates to a method for determining the exhaust back pressure p3 upstream of a turbine, which is arranged in the exhaust line of an internal combustion engine equipped with an engine management system (1), which exhaust line is intended to lead off the exhaust gas from a number cylinders of the internal combustion engine. The method includes determining the exhaust back pressure p3 upstream of a turbine, by means of which the exhaust back pressure p3 can still be determined precisely but at little cost compared to methods known in the state of the art.
