An energy recovery arrangement is disclosed for use with an engine. The energy recovery arrangement may include a closed circuit containing a high-pressure working fluid, a first boiler configured to receive waste heat from a first source on the engine, and a second boiler disposed upstream of the first boiler and configured to receive waste heat from a second source on the engine. The energy recovery arrangement may also include an energy extractor disposed at a location downstream of the first and second boilers, a condenser disposed at a location downstream of the energy extractor, and a pump disposed at a location downstream of the condenser and upstream of the first and second boilers. The energy recovery arrangement may further include a recuperator disposed in parallel with the second boiler and configured to transfer heat from working fluid exiting the extractor to working fluid exiting the pump.

Energy recovery arrangement having multiple heat sources

An exhaust emission reduction system for a fuel injected engine system has a plurality of emission reduction components configured to process the exhaust gas. The emissions reduction components include of one or more NOreduction components and one or more filtration components configured to reduce particulate matter, hydrocarbons and/or carbon monoxide emissions. Each engine cylinder is associated with a respective one of the emission reduction components, such that exhaust gas from each engine cylinder flows through the respective one emission reduction component in parallel with the exhaust gas flows from the other cylinders through their respective emission reduction components.
