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.

Affordable, efficient and durable catalytic converters for the two and three wheeler industry in developing countries are required to reduce vehicle emissions and to maintain them at a low level; and therefore to participate in a cleaner and healthier environment. The LS-Design™(Longitudinal Structure) metallic substrates with LS foils have been proved to be capable of improving conversion behavior, even with smaller catalyst size. Specially this developed foil structure, which transforms a laminar exhaust gas flow into a turbulent one, significantly improves exhaust gas mixing behaviour in the catalyst. In this special period of time where BS4 applications will start appearing in the Indian market in the near future, this publication will deal with the experimental results achieved with different metallic substrate foil structures on one leading “state of the art” BS3 four stroke motorcycle technology, developed for the Indian market.
