Six-seater three-wheelers have gained popularity among the commuters especially for their point to point low fares and better frequency compared to Municipal buses. However, pressure is mounting from all the quarters to ban these vehicles or to drive them out of the municipal limits. These vehicles with maximum loading capacity of 550 kg employ diesel engines which emit high soot & particulate matter or 2-stroke petrol engines which emit carbon monoxide as high as 13 g/km and hydrocarbon as high as 8 g/km, alarmingly high above the 1996 emission norms of 6.75 g/km CO and 5.40 g/km HC. Also the noise levels were higher. Considering the above threat, the authors had taken up the challenge to investigate and curb the pollution by employing high durability metallic catalytic converters.
