EXHAUST TREATMENT SYSTEM HAVING AN ACIDIC DEBRIS FILTER

摘要

An exhaust treatment system for a power source (10) has an air induction system (14), an exhaust system (16) and a recirculation system (17). The exhaust system includes a particulate filter (32). The recirculation system is configured to draw exhaust from downstream of the particulate filter and direct the exhaust to the air induction system. The recirculation system includes an exhaust gas cooler (44), and an acrid debris filter (48).
