Results relative to the nitrogen oxides traps

The results are obtained over a period of time, using a mixture rich in oil. We observe that during the period of rich combustion there is no more NOx at the exit of the tank. In a weak condition, we observe a slow evolution of the NOx concentration because a part of these gases is not adsorbed, and this part increases with the saturation of the adsorber. 

It is interesting to note that the ECONOX sensor reacts more quickly than the analyzer, at least at the beginning of the storage.
