Claim Text:
1. A system for a combustion engine comprising a pipe through which an exhaust fluid flows, a portion of a wall of the pipe forming a dome-shaped elevation which extends into a flow path of the fluid and a nozzle arranged in the dome-shaped elevation, the dome-shaped elevation comprising a negative incline in a direction of fluid flow and in a direction perpendicular to the direction of fluid flow converging to a maximum, wherein the dome-shaped elevation does not extend along the entire circumference of the pipe, the nozzle aligned to point in a direction that is not perpendicular to a rectilinear inner surface of the pipe, the nozzle adapted to atomize a liquid that crystallizes upon contact with the fluid flowing through the pipe, wherein said nozzle is adapted to introduce the liquid through one or more outlets into the pipe, and wherein the nozzle is arranged so that the region being sprayed or the mixing region, wherein a mixing between the liquid being atomized by the nozzle and the fluid flowing in the pipe occur, are flushed by fluid flowing through the pipe, wherein the nozzle is aligned to point into the region being sprayed and the mixing region.
