A hydrocarbon separation system for an engine fuel supply system is disclosed. The hydrocarbon separation system may include an untreated gas conduit configured to transport a raw gas stream including methane, ethane and higher carbon chainlength hydrocarbon molecules. The system may also include a separator downstream of and fluidly coupled to the untreated gas conduit configured to segregate methane or ethane of the raw gas stream from the higher carbon chainlength hydrocarbon molecules of the raw gas stream. A treated gas conduit may be located downstream of and fluidly coupled to the separator and be configured to transport the methane or ethane of the raw gas stream away from the separator. Lastly, the system may include an electronic controller configured to receive a breakthrough signal and transmit a regeneration signal in response to the breakthrough signal.

Hydrocarbon separation system

A thermal management system for an engine is disclosed. The thermal management system may have a first heat exchanger situated to cool air directed into the engine, a pump configured to pressurize a fluid directed through the engine, and a second heat exchanger situated to transfer heat absorbed by the fluid to air directed into the engine. The thermal management system may also have a heater configured to provide supplemental heat to air directed into the engine.

Engine system having cooled and heated inlet air

A thermal management system for an engine is disclosed. The thermal management system may have a first hydraulic circuit configured to circulate a fluid through the engine. The thermal management system may also have a second hydraulic circuit pressurized by the engine to heat the fluid during operation of the engine.
