With the announcement of the Euro 7 proposal, it is now clear that nitrous oxide
(laughing gas, N2O) emissions must be considered and complied with
the certification of exhaust aftertreatment systems (EATS) of commercial
vehicles (CV). This paper describes the possible formation pathways for
N2O in the EATS for different drives and uses measurement results
to show the boundary condition and the magnitude of formation as well as the
possibilities for influencing or preventing its formation.
