    Abstract: An exhaust aftertreatment system may include a reductant supply and diluent supply conduits, an injector and a control module. The reductant supply conduit includes a first valve controlling a flow of reductant through the reductant supply conduit. The diluent supply conduit includes a second valve controlling a flow of diluent through the diluent supply conduit. The injector is in fluid communication with the reductant supply conduit and the diluent supply conduit and is configured to provide fluid to an exhaust stream. The control module may control the first valve to provide a targeted amount of reductant through the injector. The control module may control the second valve to maintain a fluid flow rate through the injector that is at or above a minimum flow rate threshold of the injector based on a difference between a flow rate through the reductant supply conduit and the minimum flow rate threshold.

    Abstract: An exhaust system including a selective catalytic reduction (SCR) component and an oxidation catalyst component. The exhaust system also includes an exhaust treatment fluid injection system for dispersing an exhaust treatment fluid into an exhaust stream at a location adjacent either the SCR component or the oxidation catalyst component, wherein the exhaust treatment fluid injection device includes a common rail that provides the exhaust treatment fluid under pressure to a plurality of injectors that dose the exhaust treatment fluid into the exhaust stream. The exhaust treatment fluid injection device also includes a return rail for returning unused exhaust treatment fluid to the fluid source. Each of the common rail and return rail can be configured to allow drainage of the exhaust treatment fluid as a freeze-protection feature.

    Abstract: A method of determining an optimized position for a burner in an exhaust aftertreatment system includes estimating temperature distributions across faces of exhaust treatment devices positioned within parallel paths based on an initial burner position upstream of the parallel paths. A temperature distribution across the faces of the exhaust treatment device is again estimated based on a changed burner position. A difference between the estimates is determined. The changing, estimating and determining steps are repeated to correlate the burner position with a temperature variance across the faces. An optimized burner position is determined based on minimizing the temperature variance across the faces of the exhaust treatment devices.

    Abstract: An electronic device and a method for determining whether a vehicle suspension system has degraded by positioning the electronic device in a vehicle includes activating a camera to initiate data capture within the electronic device. The camera is positioned to capture a change in a field of view during vehicle operation. The method includes calculating a vehicle suspension operating characteristic based on information captured by the camera and determining whether the calculated vehicle suspension operating characteristic exceeds a threshold. A signal indicative of suspension degradation is output when the threshold is exceeded.

    Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine includes an outer housing, a tubular inner housing, and an injector. The outer housing includes an outer wall defining an exhaust gas passageway that can receive exhaust gas. The inner housing is disposed within the outer housing and includes a longitudinal axis, a first end, a peripheral wall, and an outlet. The peripheral wall is at least partially formed by wire mesh. The outlet is disposed at a second end of the inner housing opposite the first end of the inner housing. The injector is fixed to the inner or outer housing to dose the reductant into the interior of the inner housing. The wire mesh includes openings to receive at least a portion of the exhaust gas. The outlet of the inner housing discharges a mixture of exhaust gas and reductant.
