  • Patent number: 10890093
    Abstract: Exhaust gas treatment system (100) for a motor vehicle, comprising a first catalytic converter (101-1) for selective catalytic reduction; a second catalytic converter (101-2) for selective catalytic reduction; a first nitrogen oxide sensor (103-1) upstream of the first catalytic converter (101-1) for detecting a first nitrogen oxide value (NOx-1); a second nitrogen oxide sensor (103-2) between the first and the second catalytic converter (101-1; 101-2) for detecting a second nitrogen oxide value (NOx-2); a third nitrogen oxide sensor (103-3) downstream of the second catalytic converter (101-2) for detecting a third nitrogen oxide value (NOx-3); an electronic evaluation device (105) for calculating a first efficiency of the first catalytic converter (101-1) on the basis of the first and the second nitrogen oxide value (NOx-1; NOx-2), a second efficiency of the second catalytic converter (101-2) on the basis of the second and the third nitrogen oxide value (NOx-2; NOx-3) and a total efficiency of the exhaust ga
