Abstract:
1. A fluid flow control device for receiving and guiding exhaust gas from an engine towards an exhaust gas treatment device, comprising: a nozzle disposed within an exhaust conduit of the engine, the nozzle including an inlet opening and an outlet opening for forming a first flow path through the nozzle, the nozzle being spaced from the exhaust conduit for forming a second flow path between the nozzle and the exhaust conduit; and an injector disposed adjacent the nozzle, the injector being oriented to direct a pressurized fluid into the second flow path; wherein the first flow path forms a first axis and the exhaust conduit, along an axial length where the nozzle is disposed within the exhaust conduit, forms a second axis, the first axis and second axis being non-parallel with respect to one another.
