A flow device for an exhaust treatment system includes a base and at least one flow deflector tube secured to the base. The flow deflector tube includes a flow inlet, a flow outlet, and a passage that extends through the flow deflector tube from the flow inlet to the flow outlet. The flow outlet is at an angled orientation to the flow inlet. A method of mixing reactants and exhaust in an exhaust treatment system includes the steps of injecting reactants into exhaust gases flowing through an exhaust conduit used to convey the exhaust gases from an engine. Bent tubes are disposed in the exhaust conduit and used to mix the exhaust gases and the reactants.

Exhaust gas flow device

The present disclosure relates to an diesel exhaust treatment device including a main body having a central longitudinal axis that extends between first and second ends of the main body. A catalyzed substrate is positioned within an interior of the main body. A side inlet is positioned at a side of the main body for directing exhaust gas into the interior of the main body. A flow distribution element is positioned within the interior of the main body at a location between the side inlet and an upstream face of the substrate. The flow distribution element extends across a direction of exhaust flow through the main body and is mounted at a side of the main body that is opposite the side inlet.

Exhaust flow distribution device

The disclosure is directed to a flow distributor for use to maximize the efficiency and working life of a catalytic converter. The flow distributor is configured such that it directs the gas flow in the center of the exhaust gas stream to the periphery of the gas stream thereby resulting in a more uniform velocity flow pattern.

An exhaust filter having a pleated filter media mounted between end caps is disclosed herein. The filter has a construction suitable for high temperature environments such as engine exhaust systems.
