Abstract
A Tier 4 ready silencer that can accept both DOCs and DPFs to meet Tier 3 and can interface with an SCR system to meet Tier 4. The invention includes a silencer compartment with empty filter/catalyst banks in the shape of a V. DOCs and DPFs can be added and arranged in the V-shaped banks as needed. Various exhaust fins direct exhaust flow through the filters/catalysts. Multiple exhaust inlets to the device provide the most direct route possible from the engine outlets. A mixing tube and an SCR system can be added to the output port to comply with Tier 4.
