摘要：An exhaust system including a selective catalytic reduction (SCR) componentand an oxidation catalyst component. The exhaust system also includes an exhausttreatment fluid injection system for dispersing an exhaust treatment fluid into an exhauststream at a location adjacent either the SCR component or the oxidation catalystcomponent, wherein the exhaust treatment fluid injection device includes a common railthat provides the exhaust treatment fluid under pressure to a plurality of injectors thatdose the exhaust treatment fluid into the exhaust stream. The exhaust treatment fluidinjection device also includes a return rail for returning unused exhaust treatment fluid tothe fluid source. Each of the common rail and return rail can be configured to allowdrainage of the exhaust treatment fluid as a freeze-protection feature.
