Abstract
An exhaust post-treatment device is designed in a layered fashion and comprises an exhaust cleaning arrangement lying between a supply chamber and a transition chamber with soot filters lying at both sides of a denitrification-catalytic converter unit, with the transition chamber comprising a mixing chamber open towards the denitrification-catalytic converter unit, in which starting at the soot filters via separate guide channels, the exhaust is injected in the opposite direction of flow and which mixing chamber is limited by guide panels, which form walls of the guide channels extending encompassing along the housing towards the mixing chamber.
Claims10
An exhaust post-treatment device, particularly for diesel engines, comprising:
- a housing comprising supply connections at a housing side, an exhaust cleaning arrangement accepted by the housing and located in a connection between the supply connections, wherein the exhaust cleaning arrangement comprises a soot filter unit and a denitrification-catalytic converter unit arranged adjacent thereto, which are axially flown through oppositely and are connected to each other via a transition chamber, located side-by-side and perpendicular in reference to a direction of flow, wherein the transition chamber in reference to the exhaust cleaning arrangement is axially opposite to the supply connections, and wherein the soot filter unit is divided into two longitudinally opposite soot filters arranged at lateral housing walls and that the denitrification-catalytic converter unit is arranged lying between the soot filters of the soot filter unit.
