Abstract
A method for managing operation of a component of a system for storing and injecting an additive into exhaust gases of a combustion engine. The system includes a container for storing the additive and the method includes: obtaining an instantaneous measurement of concentration of additive and/or an instantaneous measurement of alkalinity of the additive and/or an instantaneous measurement of the temperature inside the container, by one or a plurality of measurement sensors mounted inside the container; determining reducing power of the additive based on the instantaneous measurement of concentration of additive and/or an instantaneous measurement of the alkalinity of the additive and/or temperature inside the container; generating a control signal, based on the defined reducing power; transmitting the generated control signal to the component.
