    Abstract: An aftertreatment system for treating exhaust gas discharged from a combustion engine may include a particulate filter, a reductant-injection system, an ammonia sensor and a control module. The particulate filter may be configured to filter exhaust gas discharged from the combustion engine. The reductant-injection system may be configured to inject a reductant into a stream of the exhaust gas upstream of the particulate filter. The ammonia sensor may be configured to sense a concentration of ammonia in the stream of exhaust gas downstream of the particulate filter. The control module may be in communication with the ammonia sensor and may determine a soot load of the particulate filter based on data received from the ammonia sensor.

    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.
