An injector comprises at least one injection nozzle, a dosing system to provide a dosed flow of reducing agent to the at least one or each injection nozzle, and an injection line fluidically connecting the dosing system to the at least one or each injection nozzle. The injection line comprises an upstream pipe fluidically connected to the dosing system, at least one downstream pipe fluidically connected to a respective injection nozzle, and at least one anti-backflow device to avoid or minimize fluidic flow from the at least one or each downstream pipe toward the upstream pipe.

Injector for injecting a gaseous reducing agent into an exhaust gas stream, comprising at least one anti-backflow device

A mixer for a vehicle exhaust system includes an outer housing that defines an internal cavity, an inlet pipe that directs exhaust gas into the internal cavity, and an outlet baffle. The outer housing includes a doser opening configured to receive a doser. The outlet baffle directs a mixture of the exhaust gas and a reducing agent injected by the doser into a downstream exhaust component. A deflector deflects exhaust gas exiting the inlet pipe to mix with the reducing agent prior to entering the downstream exhaust component.
