Description

The usage of automobiles has been increasing expotentially which also increasing emission of pollutants like hydrocarbons, carbon monoxide, oxides of nitrogen and particulate matter greatly. These pollutants have negative impact on air quality, the environment and human health. The stringent regulations are in force across the globe to minimize it. Automotive Emissions and Its Control provides an up-to-date reference to academicians and professionals on emissions from SI and CI engines powered vehicles and its control technologies. In this book engine design, engine emissions, impact of emitted pollutants on environment, worldwide vehicle emission standards etc. are presented. The pollutant emission control technologies like improvement in engine design, fuel pretreatment, use of alternative fuels, fuel additives, exhaust treatment or better tuning of the combustion process etc. are discussed in the detail. The recent developments on exhaust aftertreatment such as cold start emission control, NSR, SCR and diesel particulate filters etc. are covered in the book. It also discuses three way catalytic converter based on noble metal for minimizing emissions with its limitations.
