Title: SYSTEM FOR RECOVERING ENERGY
Abstract:
The present invention describes a system for recovering energy (30) in an exhaust circuit (3) of a heat engine (1), comprising: an exhaust line (5); a valve for controlling the exhaust flow rate (17); a recirculation line (6) arranged to receive exhaust gases from the heat engine (1), the recirculation line (6) comprising a heat exchanger (7); an auxiliary duct (9) connecting the exhaust line (5) and the recirculation line (6); a three-way valve (11) provided at the junction (10) between the auxiliary duct (9) and the recirculation line (6), the three-way valve (11) being arranged to control the flow rate of gas circulating in the auxiliary duct (9) and the flow rate of gas circulating in the recirculation line (6), the heat exchanger (7) being partially integrated into a device (20) for pollution control of the exhaust gases of the heat engine (1).
