    Abstract: Systems and methods for internal combustion engine operation with exhaust gas recirculation and turbocharging are disclosed. The systems include an exhaust gas recirculation loop for recirculating exhaust gas flow from a first portion of the cylinders of the engine into an intake system prior to combustion. The system further includes a turbine with first and second inlets for receiving exhaust gas flows from respective first and second parts of the exhaust gas of the remaining portion of the cylinders.

    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.
