Abstract
The invention relates to an exhaust line (40) of an internal combustion engine comprising an exhaust duct (43) for the burnt gases and a fuel injector (53) giving into said exhaust duct. According to the invention, a plurality of flat vanes (101, 102, 103, 104) are provided in the exhaust duct (43) so that one face of each vane (101, 102, 103, 104) receives a portion of the fuel (54) jet from said fuel injector (53).
