The ultimate goal of vehicle emissions control devices and programs are to improve ambient air quality, hence analysis of programs and technology effectiveness should focus as much as possible on real-world emissions reduction. Some of the significant implications of this work are the need for vehicle exhaust emissions guidelines in developing countries, as well as enlightening drivers on the use of catalytic converters in their vehicles. In this book, a mathematical formula was developed for quantifying vehicle emissions as well as set up illustrations and results of laboratory analysis...
