Title: OXIDATION CATALYST FOR WASTE HEAT RECOVERY PERFORMANCE IMPROVEMENT
Abstract:
An exhaust system for an engine include a first exhaust system portion that receives exhaust from one or more combustion chambers of the engine. The exhaust system also includes an oxidation catalyst having an inlet and an outlet. The inlet of the oxidation catalyst is in fluid communication with the first exhaust system portion and receives exhaust from the one or more combustion chambers of the engine. The exhaust system also includes a second exhaust system portion that receives exhaust gases downstream from the outlet of the oxidation catalyst. A waste heat recovery system is in thermal communication with the second exhaust system portion that receives exhaust gases from the outlet of the oxidation catalyst. In some instances, the exhaust system may omit other aftertreatment components.
