EXHAUST TREATMENT SYSTEM

摘要

A system for ventilating a crankcase of an internal combustion engine (12) includes an exhaust system (10) having a treatment element (19), and the treatment element (19) includes a catalyst (18) configured to assist in passively regenerating a filter (16) of the exhaust system (10). The system for ventilating the crankcase also includes first flow path configured to transmit a first flow from the crankcase to a port (46) upstream of the filter (16), and a second flow path configured to transmit a second flow from a combustion chamber of the internal combustion engine (12) to the exhaust system (10). The catalyst (18) is configured to treat a combined flow comprising the first flow and the second flow.
