Everything you need to learn about controlling air pollution from motor vehicle emissions. Introduction: Transportation in India, is the major emission source of three primary pollutants- hydrocarbons (HCs), carbon monoxide (CO) and nitrogen oxides (NOx). Most of these emissions are associated with light- duty cars and trucks. Heavy-duty trucks, motorcycles and off-road vehicles are also significant sources. In urban areas, [...]

Both engine modifications and specific control technologies have been used to control motor vehicle emissions. These have included engine operation and design factors, engine-based control systems and exhaust gas control systems. Early control efforts were directed to reducing blow-by gases, evaporative emissions and HCs and CO from exhaust systems. 1. Engine Operation and Design: Significant reductions in emissions of CO, [...]
