an external casing in which a diesel oxidation catalyst (DOC) and a bypass duct of the DOC is housed to define a bifurcation for the exhaust gases passing through the device, so that a first flow of the exhausted gases is intended to pass the DOC and a second flow of the exhausted gases is intended to bypass the DOC,
a first injector of an urea-based reducing agent arranged at or at a point immediately downstream of the bifurcation for injecting the urea-based reducing agent in the second flow and
an electric heater arranged annularly with respect to the bypass duct and configured to heat the bypass duct and to be passed by the first flow.
