[EN] The incoming emission regulations for internal combustion engines are gradually introducing new pollutant species, which requires greater complexity of the exhaust gas aftertreatment systems concerning layout, control ...

[EN] The control of selective catalytic reduction (SCR) systems, via NH3 injection, requires from a precise estimation of the SCR load in order to ensure NOx reduction by minimizing ammonia slip. This article aims to resolve ...

[EN] This work presents the development of a model to capture the NOx sensors cross sensitivity behavior based on NO(x )sensor cell temperature, as well as a model do predict the slip of the NOx and NH3 after the SCR ...
