Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system for a diesel type internal combustion engine including a circuit for partial recirculation of exhaust gases, comprising: means for estimating intake air parameter set point values; means for estimating exhaust richness; means for determining an intake richness set point value as a function of the estimated intake air parameter set point values; and means for correcting at least one of the intake air parameter set point values as…
