"textContent": "The device has a determination unit (27) determining an increase per unit time of a mass of nitrogen oxide as a function of a mass of oxide stored in a nitrogen oxide trap, a trap temperature and oxide flowrate, when exhaust gases in the trap are lean. The unit determines a reduction per unit time of the mass of the oxide as a function of the temperature of the trap and richness of the gases, when gases in the trap are rich. An independent claim is also included for a system for supervising a regeneration of a nitrogen oxide trap in an exhaust line of a motor vehicle engine, comprising a device for determining mass of oxide stored.",
