Abstract:
A method and apparatus for improving recirculation of exhaust gas in an internal combustion engine having an exhaust-gas turbocharger, in particular in a diesel engine, determines operation parameters of the engine in order to determine exhaust gas pressures, supplies compressed air in a controlled manner based on the exhaust gas pressures in order to generate a vacuum in a supply section of a gas supply device, thereby inducting a partial quantity of exhaust gas from the engine into the supply section using the vacuum, and recirculates the partial quantity of exhaust gas into the engine via an induction line connected to the gas supply device.
