Zusammenfassung:The invention relates to an exhaust gas after-treatment system for reducing nitrogen oxide by means of SCR for a vehicle with an internal combustion engine comprising at least two exhaust gas pipes (21), which respectively contain an SCR-catalyst (24) and upstream therefrom respectively an additive injection chamber (22), and an additive tank (1) which supplies said injection chambers (22). On each of said exhaust gas pipes (21) an associated additive injection dosing unit (11) and an associated additive injection supply unit (10) are provided, said supply units (10) are respectively connected to the additive tank (1) by means of a forward line (2 +2.1, 2+2.2) and the respective forward line (2+2.1, 2+2.2) have essentially the same line lengths to the supply units (10).
