The control of the mixture composition for an internal combustion motor fitted with an NOx catalyst which stores the separated NOx, during the regeneration phase, the lambda value (amount of air introduced versus theoretical air demand) of the exhaust fed to the catalyst ( lambda M) is corrected towards a value of 1 during regeneration according to the value of the exhaust ( lambda K) leaving the catalyst. The catalyst is regenerated when the NOx level breaches a threshold value, or the emitted exhaust lambda value exceeds a threshold level.",
