ABSTRACT:
In internal combustion engines in which residual burnt gases (GBR) exist and in which a recirculation of exhaust gases (RGE) is provided as well as the engines in which the gas mixture is low in gasoline or in the case of diesel engines, a digital value Cg, representative of the average gas torque per combustion and provided by a system, not shown, is corrected as a function of total rate q of recirculation of the exhaust gases and the presence of the residual burnt gases. The correcting device comprising calculating means (56) for producing a correction factor Q.sub.2 -(1-p.sub.2.q), in which p.sub.2 is a constant close to 0.50 and q, the value of said total rate, then applying this factor Q.sub.2 to value Cg, if necessary previously corrected as a function of richness r of the gas mixture when r<1, for providing a corrected digital value (Cg).sub.q or (Cg).sub.r,q. Other devices are provided for correcting Cg in the case of excess oxidant and in the case of diesel engines.
