摘要
The invention concerns a elongation valve for controlling the flow rate of exhaust gases recycled in intake manifold (1) of the engine (1, 2, 3). The invention is characterised in that it consists in: calculating the air flow rate (Q0) with closed control valve (5), on the basis of the engine speed (Nmot), the pressure (Pco1) in the intake manifold (1), the temperature of the air (Tair) sucked in by the engine, and a filling rate (C0) of the engine cylinders, and calculating the air flow rate (Qair) with open control valve (5) from the expression: Qair = Qo f1f2/1 + C4.f2, wherein (f1) and (f2) are correcting factors and (C4) a calibrating factor based on the engine speed (Nmot). The invention is applicable to diesel engines supercharged with air.
