Affordable, efficient and durable catalytic converters for the Commercial Vehicle and Non-Road industry in all countries are required to reduce vehicle emissions under real world driving conditions and fulfill future legal requirements. Specially for India traffic conditions and payload to engine size conditions new cost-effective solutions are needed to participate in a cleaner and healthier environment. Metallic substrates with structured foils like the Transversal StructureTM (TS) or the Longitudinal StructureTM (LS) have been proved to be capable of improving conversion behavior, even with smaller catalyst size. Now Vitesco Technologies is developed a new Substrate for Heavy duty applications that specifically maintains the geometric surface area at a very high level and improves further the mass transport of the pollutants, which potentially leads together to very high pollutant conversion rates.

Besides the further reduction of the harmful gaseous emissions (HC, CO and NOx) to reach upcoming emission limits, the discussion on lowering the CO₂ emissions is omnipresent. From engine development point of view further optimization of the stoichiometric-operated gasoline engine as well as the introduction of lean-operated engines are the main development trend. The emission control system can support the engine development by dedicated catalyst technologies as presented in this paper. A new family of TWC technologies offers to tune the catalyst system to the engine performance and the back pressure requirement - which helps to reduce CO₂ emissions. In addition these technologies show improved performance in HC, CO, NOx light-off, and in CO and NOx conversions under dynamic conditions - this again can positively impact the CO₂ emissions as less harsh heating strategies for cold start is required.
