Problems solved by technology

[0004] A disadvantage of the prior art is that the length of the mixing section determines or affects the extent to which the reductant mixes with the exhaust gas inside the exhaust system and therefore also determines or affects how effective the system is at reducing NOx emissions
If the mixing section is too short, the NOx conversion will be low

Embodiment Construction

[0040] Hereinafter, the present invention will be illustrated by means of embodiments. It should be understood, however, that these embodiments are included to illustrate the principles of the invention and not to limit the scope of the invention, which is defined by the appended claims.

[0041] figure 1 An exhaust gas treatment arrangement (1) for treating exhaust gas flowing along a flow path (2) in an exhaust pipe system (3) is shown. Hereafter the name "exhaust gas treatment arrangement (arrangement)" is equivalent to "arrangement". The exhaust pipe system (3) is configured to be arranged in a vehicle and to be connected to an engine or motor (eg internal combustion engine) in the vehicle. The flow path (2) extends from the engine towards the outlet at the end portion of the exhaust pipe system (3) through the exhaust pipe system (3). The device (1) comprises a supply element (4). The supply element (4) can be in communication with a source (5) comprising ammonia gas....

Abstract

The invention relates to an exhaust gas treatment arrangement (1) and a method thereof for treating exhaust gases flowing along a flow path (2) in an exhaust pipe system (3). The arrangement (1) comprises a supply element (4) being in communication with a source (5) comprising an ammonia gas. The supply element (4) comprises at least two discharge apertures (6a, 6b, 6c) being adapted to communicate with the flow path (2) such that the ammonia gas may be dispersible from the discharge apertures (6a, 6b, 6c) into the exhaust gases in the flow path (2) in at least two discharge directions (7a, 7b, 7c).

Description

technical field [0001] The invention relates to an exhaust gas treatment arrangement for treating exhaust gas flowing along a flow path in an exhaust pipe system. Furthermore, the invention relates to a method of treating exhaust gas flowing along a flow path in an exhaust pipe system. Background technique [0002] The internal combustion engine therein produces exhaust gases when the vehicle is running. The resulting exhaust gases may include particles or elements that may be harmful to humans, animals and / or nature. Over the years, various attempts have been made to reduce the amount of these harmful particles or elements from exhaust gases. It has been found that the presence of catalytic converters in the exhaust system for the treatment of exhaust gases results in lower levels of nitrogen oxides (NOx). Further improvements in the reduction of NOx in the exhaust gas have already been achieved in catalytic converters by mixing reducing agents into the exhaust gas prior...
