Abstract
System for controlling an engine provided with an exhaust gas post-treatment system of the selective catalysis type, including a closed-loop control of NObefore the gas post-treatment system, according to the following steps: ⋅ a unit for determining a NOsetpoint in dependence on the rotational speed and the torque setpoint of the engine, ⋅ a unit for determining a NO value, and ⋅ a cascade control unit which is able to determine a setpoint for admitted oxygen and a correction of the supercharging pressure destined for unit for controlling the air loop of the engine as well as a correction of the injection pressure and a correction of the advance of the main injection in dependence on a NOdifference, between a NOx emission setpoint or corrected emission setpoint and a determined value of the quantity of NO.
