Compact flow-blowing DEF Mixer

摘要

The present invention is a device that enables good DEF mixing performances at low backpressure, giving the possibility to easily tune the trade-off between them, Working principle is the creation of a turbulence on the gas flow motion by means of specific channels (1 ) that blow the gas, collected upstream the DEF Mixer (2), against the DEF injector (3) or in the flow motion direction. Channels are integrated into an impacting grid with a unique shape with flaps (4) that favor the DEF spray atomization.
