ABSTRACT:
Method for controlling the braking effect during engine braking in an internal combustion engine (10) having an exhaust turbocharger unit (16) with adjustable guide blades for controlling the turbine speed and gas flow. The method includes detection of the engine speed, detection of the adjustment position of the guide blades, measurement either of the charging pressure on the intake side of the engine or the manifold pressure on the exhaust side of the engine, comparison of these data with stored desired values, and adjustment of the guide blades to a desired position which gives a suitable braking effect for the prevailing charging pressure.
