Abstract (en)
[origin: WO2009098384A1] The invention relates to a method for measuring the mass flow (Q m ) of exhaust gases circulating in an EGR system of a heat engine of a motor vehicle, the mass flow being measured by using the geometry (S 1 / S 2 , point 1, point 2) of the circuit (10) of the EGR system at a negative-pressure element on the course of the EGR gases.
