Abstract

Es wird ein Abgasrückführungssystem (14) einer Brennkraftmaschine, insbesondere eines Dieselmotors (10), insbesondere eines Kraftfahrzeugs, beschrieben. Das Abgasrückführungssystem (14) weist ein Abgasrückführventil (24) auf, welches in einer Abgasrückführleitung (16) zwischen einer Abgasleitung (18) und einer Frischgasleitung (20) angeordnet ist. Das Abgasrückführventil (24) ist als Abgasrückführmodul (22) mit wenigstens einem weiteren Funktionsbauteil (26, 28, 30) des Abgasrückführungssystems (14) realisiert.

An exhaust gas recirculation system (14) of an internal combustion engine, in particular of a diesel engine (10), in particular of a motor vehicle, is described. The exhaust gas recirculation system (14) has an exhaust gas recirculation valve (24) which is arranged in an exhaust gas recirculation line (16) between an exhaust gas line (18) and a fresh gas line (20). The exhaust gas recirculation valve (24) is realized as an exhaust gas recirculation module (22) with at least one further functional component (26, 28, 30) of the exhaust gas recirculation system (14).
