Exhaust emissions from Diesel vehicles are now a day’s more concern. Diesel vehicles emit more amount of NOx than the petrol driven vehicles. Due to implementation of stringent emission norms BS IV, it is the demand to develop a catalytic converter which shall reduce the emission considerably. This paper summarizes the problem and solutions of NOx emission from diesel vehicles. In this paper an experimental investigation of two designs (Cylindrical and Convergent-Divergent shape) of diesel catalytic converter in the Jeep exhaust gas stream is reported. Two transition metal oxide catalysts (5% Ag and 5% Fe) loaded over alumina support were filled in these catalytic converters and heated externally by means of a heating tape upto 2800C. In 5% Silver loaded catalyst, the maximum NO conversion of 36.36% achieved at temperature of 2800C under full acceleration in the cylindrical catalytic converter and 31.41% conversion with Convergent-divergent catalytic converter. When 5% Iron catalyst was tested in Cylindrical catalytic converter the NO conversion was 27.08% and with Convergent-divergent catalytic converter it was 25.25% at 2800C. Transition metal oxide based catalytic converter containing 5% Silver and Iron catalyst is an efficient system to reduce the NOx emission from diesel exhaust. Introduction of new future fuels will also be able to reduce NOx emissions in near future.
