An arrangement for injecting a reducing agent into an exhaust line of a combustion engine (1). An exhaust line (3) leads exhaust gases from the engine. A first turbine (4) is in the exhaust line (3). A second turbine (20) in the exhaust line is downstream of the first turbine (4) in the intended direction of flow in the exhaust line. An injector (19) injects reducing agent into the exhaust line (3) so that it is warmed and vaporised by the warm exhaust gases in the exhaust line (3), and an SCR catalyst (29). The injector (19) is in the exhaust line downstream of the first turbine (4) and upstream of the second turbine (20). |
