Description Two wheelers constitute almost three fourths of the
vehicular population in developing countries like India,
and consequently they are the major contributors to
vehicular pollution. Catalytic converters based on nonnoble
metal catalyst have been developed for 2-stroke, 2-
wheelers application. In this study a modified and
thermally stable alumina washcoat has been developed
for application of non-noble metal catalyst. Alumina
washcoat has been used on both ceramic and metallic
honeycomb substrates and subsequently the perovskite
type of catalyst has been synthesized in-situ on alumina
washcoated substrates. Extensive characterization was
carried out during development of alumina washcoat and
synthesis of perovskite catalyst to establish the thermal
stability of alumina washcoat and phase formation of
catalysts. A number of prototypes based on alumina
supported perovskite have been prepared and tested for
mass conversion efficiency with respect to CO, HC and
NOx. The results reveal the confirmation of performance
of converter for EURO-I emission norms, which are
presently applicable in India for 2-stroke, 2-wheelers. The
optimized design of converter minimizes the pressure
drop across the converter and the power loss of the
engine is well within tolerable limits.
