Abstract. Emission from vehicles especially automobiles is responsible for about two third of air pollution in the urban area. The major pollutants emitted by motor vehicles including CO, NOx, sulphur oxides, (SO), HC, lead (Pb) and suspended particulate matter (SPM), have damaging effects on both human health.
The combustion of gasoline and diesel fuel in vehicle engines produces emissions of several potentially harmful substances. These emissions are not solely the result of the combustion process, nor do they come only from the tailpipe of the vehicle; rather, they result from a combination of the engine design and the fuel

Aug 5, 1994 Cars and Pollution. Emissions from an individual car are generally low, relative to the smokestack image many people associate with air pollution. But in numerous cities across the country, the personal automobile is the single greatest polluter, as emissions from millions of vehicles on the road add up.
The emissions from millions of vehicles add up. These emissions are byproducts from the engine combustion process and from the evaporation of fuel. Despite the ever-growing number of vehicles on the road, studies show that ten to thirty percent of vehicles cause the majority of vehicle-related air pollution. This fact sheet

Sources of Vehicle Emissions. The power to move a motor vehicle comes from burning fuel in an engine. Pollution from vehicles comes from the by-products of this combustion process. In addition, volatile organic compounds (VOC) escape through fuel evaporation. As vehicle exhaust systems have improved, evaporative
Stringent regulations governing automobile exhaust emissions are due to come into force in the United States. Johnson Matthey have undertaken the development of platinum-based catalytic reactors for control of these exhaust emissions. Two new types of catalyst have demonstrated the feasibility of exhaust control by

Automobiles are a necessary evil, while they have made living easy and convenient, they have also made human life more complicated and vulnerable to both toxic emissions and an increased risk of accidents.
