Abstract
An in-line filter assembly for filtering engine exhaust gases utilized by turbocharged internal combustion engine systems. The filter assembly includes an external housing having a lower housing section and an upper housing section. The upper housing section further includes an air inlet port and an air outlet port. A filter unit for decontaminating the exhaust stream is positioned below the air inlet port. An interior chamber is in communication with the outlet port and surrounds the filter unit. A spring positioned directly beneath the filter unit stabilizes the filter unit within the chamber and urges the filter unit upward into sealing engagement with the inlet port. The lower housing section also includes a sump for collecting contaminants captured by the filter unit.
