| 摘要 |
The invention concerns a method for controlling an energy recovery system (30) of an exhaust line (40) of a motor vehicle engine (1), the energy recovery system comprising a bypass duct (31) pierced into an exhaust duct (41) of the exhaust line and comprising a heat exchanger (32), and a bypass valve (33) arranged in the exhaust duct, at the inlet of the bypass duct, designed to take up different positions, said method comprising the following steps: a) defining (100) values of the injected fuel flow rate, the inlet air flow rate, the temperature and flow rate of the exhaust gases; b) defining (200) an optimum position of said bypass valve on the basis of a fuel consumption saving corresponding to the values defined in a), and an overconsumption of fuel corresponding to the values defined in a) and to the optimum position of the bypass valve; c) positioning (300) the bypass valve in the optimum position defined in step b). |
