Abstract:
A system for controlling a diesel internal combustion engine including a circuit for partially recirculating exhaust gases, including a mechanism estimating set values of intake-air parameters; a mechanism estimating richness of the exhaust gas; a mechanism determining a set value of the intake richness according to set values of the intake-air parameters; and a mechanism correcting at least one of the set values of the intake-air parameters according to the estimation of the richness of the exhaust gas and the richness set value.
