摘要

The invention provides an arrangement (10) for the pollution control of a motor vehicle internal combustion engine, of the type which comprises at least one exhaust line, which comprises at least one fuel injector (12), arranged in a given conduit (14) of the exhaust line upstream of a particle-filtering element, for producing a mixture of fuel and exhaust gas that is intended to be ignited in the filtering element, characterized in that the given conduit (14) comprises on its internal wall (22) a projecting element (24), arranged substantially so as to face the injector (12), which is intended to promote the vaporization of the fuel in the mixture.
