    摘要： A selective catalytic reduction (SCR) system includes a mixer that has a plurality of blades spaced about a central tube. The mixer can be configured to receive a reductant and exhaust gas mixture. The SCR system also includes a closed-end tube that is downstream of the mixer and configured to receive the reductant and exhaust gas mixture from the mixer. The closed-end tube includes a closed end opposing an open end. The closed end is substantially perpendicular to an exhaust flow direction. The closed-end tube further includes a sidewall that extends between the open and closed end. The sidewall can include a plurality of perforations. The flange plate of the SCR system includes an annular disk that has a plurality of openings through which reductant and exhaust gas mixture received from the closed-end tube is flowable. The flange plate is coupled to and supports in place the closed-end tube.

    摘要： Described herein is a sensor module for sensing characteristics of a fluid flowing through a fluid conduit. The sensor module includes a sample probe with at least one sample arm that extends radially inwardly from a sidewall portion of the fluid conduit to a center portion of the fluid conduit, defines a fluid flow channel, and includes a plurality of inlet apertures. The sample probe also includes a sensor well that is located at a radially outer end of the at least one sample arm. The sensor well defines an interior volume that is in fluid communication with the fluid flow channel, an upstream portion closed to an first portion of the fluid conduit upstream of sensor well, and a discharge aperture open to a second portion of the fluid conduit downstream of the sensor well. The sensor module also includes a sensor positioned in the interior volume.

    摘要： An internal combustion engine system of the present application includes a spark-ignited internal combustion engine that is powered by a gaseous fuel. The engine system also includes an exhaust system that is in exhaust gas receiving communication with the internal combustion engine. The exhaust system includes an exhaust treatment component. Additionally, the exhaust system includes a liquid fuel injection system in liquid fuel injecting communication with the exhaust system to inject liquid fuel into exhaust gas upstream of the exhaust treatment component.
