<p>The device has a main exhaust conduit (1) exhausting fuel towards a pollution control unit (2) e.g. oxidation catalyst or particle filter. A fuel injector (3) injects fuel to be exhausted in the conduit in upstream of the injector, where flow of exhaust gas is partially derived in the upstream of the injector in a secondary branch (4) fixing the conduit at a level of a section restrictor (1a) in front of the pollution control unit.</p> |
