Arrangement for supplying a medium into an exhaust gas conduit in an internal combustion engine

The present invention relates to the equipment for supplying a medium to the exhaust line (3) of a combustion engine (1). This equipment -- at least [of an element (10a-10d) ] -- the medication equipment (4, 5, 6, 7, 9) to which the above-mentioned medium was supplied is included to the 1st exhaust passage (12) 画成 (ed) by the 1st wall surface (10a'-10d') and the above-mentioned 1st exhaust passage. This equipment includes a means by which the degree of heating of the 1st wall surface (10a'-10d') is maintained so that the 1st wall surface may become a temperature higher than the evaporating point of a medium, when a liquid medium is supplied in the 1st exhaust passage (12). So, even the medium which reaches to the 1st wall surface (10a'-10d') will evaporate certainly in the 1st exhaust passage (12).
