A technical summary of Euro 6/VI vehicle emission standards
theicct.orgthe Euro 3 level, and in the Euro 6 standards the NO. X. limit is 84% lower than the Euro 3 level. This has significant implications for control technologies, requiring for the first time the integration of emission control aftertreatment for NO. X. emissions, such as selective catalytic reduction, lean NO. X. traps, or others.
