Claim 0:
1. 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 first heat exchanger and a second heat exchanger of the EERS, thereby to transfer heat from the exhaust gas to fluid of a first heat distribution element and a second heat distribution element, respectively;
controlling a flow of the exhaust gas from the manifold to the first heat exchanger and the second heat exchanger by operating a first control valve and a second control valve, respectively, based on a temperature of a medium associated with the first heat exchanger and the second heat exchanger, respectively, the first control valve positioned between the manifold and the first heat exchanger, and the second control valve positioned between the manifold and the second heat exchanger; and
returning the exhaust gas to the exhaust duct via an outlet duct of the EERS, the outlet duct being in fluid communication with the exhaust duct downstream of the inlet valve.
