A mounting system is provided that mounts a fairing to the cab of a semi-tractor in a manner that hides the fasteners from view. The mounting system provides quicker assembly and disassembly among others. The mounting system may include anchor pins at one end section of the transition fairing, a single mounting screw at the opposite end section of the transition fairing, and one or more fasteners of the Snaploc&#xae; type at the mid-section of the transition fairing. Each of the couplings interface with a suitable corresponding bracket, etc, in order to mount the fairing to the associated surface of the vehicle.

Various diffusion apparatuses are provided for facilitating the injection of a nitrogen-oxides reductant solution, such as urea, into exhaust gas as part of a selective catalytic reduction system. These diffusion apparatuses direct exhaust gas from an exhaust pipe, through a conduit, and into a diffusion chamber where urea is injected. The flow of exhaust gas through the conduit provides improved transport of injected reductant solution into the exhaust pipe, and adhesion of the reductant solution to the walls of the diffusion chamber is reduced.

Reductant delivery device

A flow diffuser for vehicles of the type having an engine and an exhaust pipe generally includes a substantially tubular body having an outer surface and a first end configured for attachment to an exhaust pipe. The flow diffuser further includes a diffusion portion including at least one channel having a root end located near the outer surface, an exit port, and a channel axis extending between the root end and the exit port, the channel increasing in flow area along the channel axis to reduce exhaust gas velocity.
