The invention is directed to a method and an arrangement for enriching the oxygen content in the intake air of an internal combustion engine. To enrich the oxygen content, air is conducted through a membrane which is primarily permeable for oxygen molecules. This membrane is mounted in an enrichment channel which opens into the intake channel of the engine. The oxygen content in the intake channel is continuously detected by at least one sensor device. On the one hand, a reduction of the toxic emissions of the engine is provided while, on the other hand, an increase in the power of the engine is simultaneously provided. This is achieved with a drivable actuator device which changes the concentration of the inducted air as well as the oxygen-enriched air in dependence upon the detected oxygen content.
