Abstract
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. Together with active temperature management this solution will maintain a high conversion rate under all driving conditions.
The paper will describe the new “EVO” metallic substrate and will cover the durability and performance aspects with experimental emission measurements under relevant testing cycle on engine bench. The results will be discussed and the benefits of the EVO metallic substrate for a Commercial Vehicle and Off-road application will be drawn.
