Abstract:
An exhaust mixer is provided which may be used for mixing an additive, such as urea, in an exhaust fluid flow. The exhaust mixer may be useful in reducing or preventing build-up of solid additive deposits by increasing the efficiency of mixing of the additive. The exhaust mixer (100) may be located at least partially within a mixing conduit and comprises a plurality of elongate mixing blades (111-115) held in a spaced configuration by a support (130). Each mixing blade may have a longitudinal axis extending along a longitudinal axis of the mixing conduit, wherein an injector module may be located upstream of the inlet of the mixing conduit.
