Abstract

Verfahren zur Überprüfung einer Abgas mit einer Abgasrückführrate vom Auspufftrakt zum Ansaugtrakt rückführenden Abgasrückführanlage einer Brennkraftmaschine, bei dem eine bestimmte Veränderung der Abgasrückführrate (Δ AGR) eingestellt, die NOx-Konzentration (NOx1, NOx2) im Abgas gemessen und bei Ausbleiben einer bestimmten von der Veränderung der Abgasrückführrate abhängigen Konzentrationsdifferenz ein Defekt der Abgasrückführanlage festgestellt wird.

Figure 00000001
Method for checking an exhaust gas with an exhaust gas recirculation rate from the exhaust tract to the intake tract exhaust gas recirculation system of an internal combustion engine, in which a specific change in the exhaust gas recirculation rate (ΔAGR) is set, the NOx concentration (NOx1, NOx2) in the exhaust gas is measured and, if no specific change occurs the exhaust gas recirculation rate-dependent concentration difference, a defect in the exhaust gas recirculation system is determined.
