Abstract
A diesel exhaust treatment system for treating exhaust gas from a diesel engine comprising at least one diesel oxidation catalyst (DOC), at least one diesel particulate filter (DPF), at least one diesel exhaust fluid mixing chamber and at least one selective catalytic reduction converter (SCR). In one desirable embodiment, two DOCs, two DPFs, two SCRs, and two diesel exhaust fluid mixing chambers are arranged in parallel. The disclosed system is configured to reduce back pressure and increase urea vaporization while effectively using available space and providing improved access to components. The system can be coupled to a vehicle frame rail, such as the frame rail of a heavy duty truck.
