Zusammenfassung:	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. L'invention porte sur un système (21) de récupération d'énergie d'échappement de moteur. Le système comprend un système d'échappement (12) comprenant une première branche d'échappement (110) et une seconde branche d'échappement (120). Le système (21) comprend un premier et un second groupe de soupapes d'échappement (56, 58) associés à une pluralité de cylindres de moteur (52). Le système (21) comprend également un ensemble de récupération d'énergie (40). Le système (21) comprend en outre un mécanisme de commande (100) qui est configuré pour commander le premier et/ou le second groupe de soupapes d'échappement (56, 58) selon une stratégie de synchronisation déterminée sur la base d'au moins un paramètre de fonctionnement de moteur.
