System for controlling an engine provided with an exhaust gas post-treatment system of the selective catalysis type, comprising a closed-loop control of NOx before the gas post-treatment system, according to the following steps: • a means (2) for determining a NOx setpoint in dependence on the rotational speed and the torque setpoint of the engine, • a means (3) for determining a NOx value, and • a cascade control means (5) which is able to determine a setpoint for admitted oxygen and a correction of the supercharging pressure destined for means for controlling the air loop (9) 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 NOx difference, between a NOx emission setpoint or corrected emission setpoint and a determined value of the quantity of NOx.
