System for recovering engine exhaust energy

Abstract

A system (21) for recovering engine exhaust energy is provided. The system includes an exhaust system (12) including a first exhaust branch (110) and a second exhaust branch (120). The system (21) includes a first and a second group of exhaust valves (56, 58) associated with a plurality of engine cylinders (52). The system (21) also includes an energy recovering assembly (40). The system (21) further includes a control mechanism (100) configured to control at least one of the first and second groups of exhaust valves (56, 58) according to a determined timing strategy based on at least one engine operating parameter.
