An after treatment system (ATS) for a vehicle having an ATS module includes, fluidly connected in series, an inlet, a Diesel Oxidation Catalysts (DOC), a urea mixer and a Selective Catalytic Reduction (SCR), and an outlet. The inlet is fluidly connected to an output of an engine of the vehicle and the outlet is fluidly connected to an outlet tube of the vehicle. The inlet, DOC, mixer, SCR and outlet are arranged to define a substantial rectangular path of a flow (F) of exhaust gases flowing in the ATS, with the inlet and the outlet being positioned at a same vertex of the substantial rectangular path of the flow (F).

After treatment system for a vehicle

An after treatment system (ATS) for a vehicle includes, fluidly connected in series, an inlet, a urea mixer and an outlet. The inlet is fluidly connected to an output of an engine of the vehicle and the outlet is fluidly connected to an outlet tube of the vehicle. The urea mixer is provided with a dosing module, an inner element and an outer element. The inner element is configured such that a first flow of exhaust gas flow flowing from the inlet into the urea mixer flows into an first volume defined by the inner element. The outer element is configured such that a second flow flows in a volume defined between inner element and outer element, wherein the first and second flows rejoin together in a mixing chamber fluidly connected to the volume and to the first volume downstream with respect inner and outer elements.
