Claim 12:
13. A method of recovering energy from exhaust gases of an engine of a mobile power system, the method comprising:
operating the engine, the engine having an intake port and an exhaust duct;
opening an inlet valve in fluid communication with the exhaust duct, thereby to divert a portion of an exhaust gas flowing from the exhaust duct to an exhaust energy recovery system (EERS);
collecting the portion of the exhaust gas in a manifold of the EERS, the manifold positioned downstream of the inlet valve;
distributing the exhaust gas from the manifold to a plurality of heat exchangers, thereby to transfer heat from the exhaust gas to a fluid of a plurality of heat distribution elements;
controlling flow of the exhaust gas from the manifold to the plurality of heat exchangers by operating a plurality of control valves positioned between the manifold and the plurality of heat exchangers, the controlling includes operating at least one of the plurality of control valves towards an open position in response to the fluid in a corresponding one of the plurality of heat distribution elements being below a corresponding first temperature and operating the at least one of the plurality of control valves towards a closed position in response to the fluid in the corresponding one of the plurality of heat distribution elements being at or above a corresponding second temperature; and
controlling the inlet valve by opening and closing the inlet valve in response to a temperature of the fluid of one or more of the plurality of heat distribution elements.
