Summary

Over the last decades, the tightening of emission regulations for vehicles has significantly increased the size and the complexity of automotive catalyst systems. More recently, with the introduction of Euro 6 regulations, active NOx emission control has become an additional necessity, with catalytic systems based on “Lean NOx Traps” (LNT) or “Selective Catalytic Reduction” (SCR) catalysts using ammonia as a reducing agent. In either case, this NOx reduction component adds significant volume and further complexity to the emission control system. In 2017 further requirements have to be considered due to the so called Euro 6c legislation. Euro 6c will require to respect Real Driving Emissions (RDE). In addition challenging, high dynamic drive cycles will be introduced (WLTC = World Light Duty Transient Cycle).
