Abstract
Device for the abatement of pollutants of an internal combustion engine comprising an external casing in which a 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 is intended to cross the DOC and a second flow is intended to bypass the DOC, an injector of urea-based reducing agent arranged at or at a point immediately downstream of the bifurcation 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 exhaust gas flow.
