Abstract

Das erfindungsgemäße Abgasrückführungssystem für eine Brennkraftmaschine (20) weist eine von einem Einlass (10) zu einem Verdichter (14) führende Niederdruck-Zufuhrleitung (12) auf. Von dem Verdichter (14) zu der Brennkraftmaschine (20) führt eine Hochdruck-Zuführleitung (18), Mit der Brennkraftmaschine (20) ist über eine Hochdruck-Abgasleitung (22) eine Turbine (24) verbunden, an die sich eine zu einem Auslass (30) führende Niederdruck-Abgasleitung (26) anschließt. Mit der Niederdruck-Abgasleitung (26) und der Niederdruck-Züführleitung (12) ist ein Niederdruck-Rückführstrang (32) verbunden, der eine Niederdruckpumpe (34) aufweist. Durch die Niederdruckpumpe (34) ist es nicht erforderlich, in der Niederdruck-Abgasleitung (26) eine Drossel vorzusehen, so dass der motorische Wirkungsgrad nicht beeinträchtigt wird.The exhaust gas recirculation system according to the invention for an internal combustion engine (20) has a low-pressure supply line (12) leading from an inlet (10) to a compressor (14). From the compressor (14) to the internal combustion engine (20) performs a high-pressure supply line (18), With the internal combustion engine (20) via a high-pressure exhaust pipe (22), a turbine (24) is connected to the one to an outlet (30) leading low pressure exhaust pipe (26) connects. With the low-pressure exhaust pipe (26) and the low-pressure Züführleitung (12), a low-pressure feedback line (32) is connected, which has a low-pressure pump (34). By the low-pressure pump (34), it is not necessary to provide a throttle in the low-pressure exhaust pipe (26), so that the engine efficiency is not affected.
