“Investigation of High Achievable Pollutant Reduction on a “State of the Art” Indian 2 Wheelers - Technology Road Map to a Cleaner Air” 2015-32-0802

Affordable, efficient and durable catalytic converters for the two and three wheeler industry in developing countries are required to reduce vehicle emissions and to participate in a cleaner and healthier environment. As a contribution Continental Emitec started a comprehensive testing program with a state of the art 180 cc Bharat Stage (BS) III Indian motorcycle. The program consists of testing the state of the art of Metallic substrates with structured foils with various catalyst sizes and positions (original or close coupled). The publication presents a short literature survey and the results of the investigation with a big catalyst volume mounted in underfloor position as well as in close coupled position, gained over the World-wide harmonized Motorcycle Test Cycle, considering the two possible vehicle classifications of this motorcycle, Sub-Class 2.1 and Sub-Class 2.2. This catalyst is based on metal turbulent structured catalyst substrate with longitudinal foil structures (LS-Design™). The results are showing that all pollutant emissions could be reduced to very low levels if an appropriated technology road map is applied.
