| 摘要 |
The invention relates to a system for recovering energy from an exhaust gas circuit (3) of a heat engine (1), including an exhaust gas by-pass pipe (12) that includes a heat exchanger with two compartments, and has a first manifold (14) leading into one compartment (16) and a second manifold (15) leading into the other compartment (17), said system comprising a first valve (18) installed in the exhaust circuit (3) and capable of controlling the flow of gases into each of said manifolds (14, 15), and a second valve (20) intended to control the flow of gases at the outlet of the heat exchanger (13). The main technical feature of a system for recovering energy according to the invention is that the first valve (18) can only be used in two positions, a first position wherein same seals the first manifold (14), and a second position wherein same seals the exhaust circuit (3) and only allows the exhaust gases to flow into the first manifold (14). |
