ABSTRACT

Growth in population and growth in number of vehicles every year have combined together to give dramatic increase in both water and air pollution problems. The automotive vehicles have been a significant contributor to air pollution on total mass basis. According to one survey it has been shown that transportation contributes about 42% (by wt.) of the major pollutants. Motor vehicles alone contribute about 39%. Transportation contributes about 50% of the man made hydrocarbons (HC), a little over 60% of the total carbon mono-oxide (CO) emission and about 40% of the nitrogen oxide (NOx).
Major pollutants from automobiles are unburned hydrocarbon (UBHC), oxides of nitrogen, carbon monoxide, lead compounds, and oxides of sulphur. The air pollution due to these pollutants affects adversely materials, animals and human life. It reduces visibility to a large extent causing traffic hazards. The vegetarian and plants are affected badly by sulphur dioxide, photo chemical smog and lead.

A catalytic converter automobiles in the (colloquially, 'cat' or 'catcon') is a device used to reduce the toxicity of emissions from an internal combustion engine. First widely introduced on series-productionUS market for the 1975 model year to comply with tightening EPA regulations on auto exhaust, catalytic converters are still most commonly used in motor vehicle exhaust systems. Catalytic converters are also used on generator sets, forklifts, mining equipment, trucks, buses, trains, and other engine-equipped machines. A catalytic converter provides an environment for a chemical reaction wherein toxic combustion byproducts are converted to less-toxic gases. The catalytic converter was invented at Trinity College (Connecticut).
