Abstract: The invention relates to an injection arrangement for injection of a urea solution into an exhaust gas passage. The injection arrangement comprises a periphery wall element forming an inner space which has an extension in a longitudinal direction from a first closed end and a second open end, where the exhaust gases leaves the inner space, wherein the periphery wall element further comprises an inlet opening located at a radially outer position of the inner space. The injection arrangement further comprises flow means configured to create a rotating exhaust gas flow around a longitudinal center axis of the inner space of the periphery wall element and an injection member configured to inject the urea solution into the inner space, wherein the injection member comprises a plurality of injection nozzles arranged in at least two different longitudinal positions in the inner space.
