  • Method for estimating the flow rate of recirculated exhaust gas passing through a valve
    Patent number: 10619582
    Abstract: Disclosed is a method for estimating the flow rate QEGR of exhaust gases recirculated through an exhaust gas recirculation valve connecting an exhaust circuit and an intake circuit of a combustion engine, the method including the steps: —of determining a difference in pressure ?P between the upstream and downstream sides of the valve, determining a density ?EGR of the recirculated exhaust gases passing through the valve, determining a corrected effective area Seff_cor of the valve, estimating the flow rate QEGR of the recirculated exhaust gases from these three parameters.
    Type: Grant
