Vehicular Pollution in Bengaluru City (India), A Challenge and Mitigation Measures
Air pollution is one of the serious environmental concerns of the Bengaluru City, where majority of the
population is exposed to poor air quality. 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 and ecology. The
internal combustion engines need a mixture of air and fuel to burn and produce energy to propel the vehicle. These burnt
gases which come out of the exhaust are responsible for pollution. In petrol engines, the gases comprise a mixture of unburnt
hydrocarbons (HC), Carbon Monoxide (CO) and Oxides of Nitrogen (NOx). If these gases are in excess quantities, vehicular
pollution is caused. Emissions of Diesel vehicles are the concentration of CO and unburnt HC in the diesel exhaust are rather
low, both of which are compensated by high concentration of NOx and CO2. There are smoke particles and oxygenated HC,
including aldehydes and odour-producing compounds.
This paper initially presents various types of pollution emitted by vehicles in Bengaluru city, challenges and mitigation
measures by the use of various new technologies of Automobile Engineering and Alternative fuels.
