Abstract

A diesel oxidation catalyst (DOC) (10) is employed to oxidize oil contamination from gases received from the crankcase (8) through a ventilation line (12), thus eliminating any sticky, liquid hydrocarbons which typically adhere to turbocharger and charge air cooler surfaces. As the DOC requires a minimum temperature to light-off, die catalyst containment is designed for intimate contact with die exhaust manifold or turbine housing (16), which provides the temperature to activate the system.
