In this book, Human activities generate three broad sources of air pollution: stationary, mobile (outdoor) and indoor. Air pollution generated from mobile sources such as automobiles has been a burning issue and contributes major air quality problems in urban and industrialized areas Automotive vehicles are one of the main sources for carbon monoxide (CO), unburned hydrocarbons (HC), nitrogen oxides (NOx), carbon dioxide (CO2) and particulate matter (PM) emissions in the atmosphere. These pollutants have negative impact on air quality as well as on human health also on environment that leads in stringent norms of pollutant emission. This report focuses on non-noble metal (iron) based catalytic converter to control vehicular pollutants and low cost carbon scrubber made up of inert anion exchange resin. The experiments are carried out for zeolite/iron based catalytic converter on 2 wheel petrol driven vehicles and 4 wheel diesel driven vehicles. By using this catalytic converter it is found that HC is reduced by 86.9 and CO 86.8 by % in petrol engine, while 79% HSU reduction observed in diesel engine.
