Abstract
An exhaust gas treatment system for an internal combustion engine comprises an exhaust gas conduit configured to receive and to deliver exhaust gas to a downstream exhaust treatment device. An injector bay extends outwardly from the exhaust gas conduit upstream of the exhaust treatment device and an exhaust fluid injector mounts through an opening in the injector bay and is in fluid communication with the exhaust gas conduit and oriented in an upstream direction to deliver an exhaust fluid to the exhaust gas in the upstream direction. An exhaust flow baffle extends outwardly from the injector bay and into the exhaust gas in an upstream direction. The exhaust flow baffle is located upstream of the exhaust fluid injector and is configured to define a turbulent, low pressure velocity field downstream thereof and proximate to the exhaust fluid injector.
