Abstract
Disclosed is a method for estimating the flow rate Qof 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 ΔP between the upstream and downstream sides of the valve, determining a density ρof the recirculated exhaust gases passing through the valve, determining a corrected effective area Sof the valve, estimating the flow rate QEGR of the recirculated exhaust gases from these three parameters.
