Abstract
An internal combustion engine having a turbocharger with variable turbine geometry includes a compressor and an exhaust-gas turbine, whose turbine geometry can be adjusted to adjustably set the effective turbine cross section area. Using a closed-loop and open-loop control device, the operating state of the internal combustion engine can be detected, and the internal combustion engine can be adjusted as a function of the load and state. A movable limit stop is provided for limiting the control path of the variable turbine geometry, the limit stop being adjustable between a limiting position that limits the control path of the variable turbine geometry and a release position outside of the control path of the turbine geometry.
