Abstract
An internal combustion engine having an exhaust-gas turbocharger is provided. The exhaust-gas turbocharger includes a variable turbine geometry that allows for a greater range of use. The exhaust-gas turbocharger is used as a throttling device to dimension the combustion-air quantity delivered to the engine. The variable turbine geometry can be adjusted in such a way that the direction of rotation of the rotor of the exhaust-gas turbocharger is reversed. The intake pressure in the air inlet of the internal combustion engine is set as a function of the direction of rotation of the rotor.
