<p>The invention relates to an internal combustion engine (1) comprising first cylinders (2-6) and at least one second cylinder (7) and to a method for operating the internal combustion engine (1). The second cylinder (7) serves as a dispensing cylinder by feeding a portion of the exhaust gas to the fresh gas via an exhaust gas recirculation device (14). The invention provides that the injection of the fuel quantity supplied to the second cylinders (7) is regulated independent from the injection of the fuel quantity supplied to the first cylinders (2-6). As a result, the oxygen partial pressure is controlled so that the nitrogen oxide emissions of the internal combustion engine (1) are reduced.</p> |
