Abstract
In an internal combustion engine with an air separation unit and a method of realizing such an internal combustion engine, the air separation unit is able to be fed by intake air compressed by a charging unit and cooled by a charged air cooler. The internal combustion engine can at least periodically be fed with a retentate, provided by the air separation unit, having such a composition that, in comparison to normal, it is oxygen enriched. The air separation unit is connected to the outlet of the charged air cooler, and compressed intake air from the charging unit undergoes purification that includes the separation of fluid and/or solid contents before being fed into the air separation unit.
