    Abstract: 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.

    Abstract: A selective catalytic reduction (SCR) system (40) includes a mixer (50) with a plurality of blades (56) spaced about a central tube (52). The mixer can be configured to receive a reductant and exhaust gas mixture (13). The SCR system also includes a closed-end tube (60) 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 (68) opposing an open end (67). The closed-end tube further includes a sidewall (62) that extends between the open and closed end. The sidewall can include a plurality of perforations (65). A flange plate (70) of the SCR system includes an annular disk that has a plurality of openings (72) 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.
