SYSTEM AND METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE FOR A MOTOR VEHICLE IN TRANSIT

摘要

The invention relates to a system for controlling a diesel internal combustion engine provided with a circuit for partially recirculating the exhaust gases, including a means (3) for estimating set values of intake-air parameters, characterised in that it includes: a means for estimating the richness of the exhaust gas, a means (6) for determining a set value of the intake richness according to set values of the intake-air parameters, and a means (7) for 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.
