A review of control strategies for automotive evaporative emissions practiced worldwide

Air quality in India has reached to an alarming state, as 14 out of 20 most polluted cities in the world are from India. Exhaust emissions are regulated well across the world while, evaporative emissions from automobile are ignored outside United States. Evaporative emission inventory is increasing very rapidly and identified as one of the primary cause of air pollution and health problems especially in Asian countries like China and India. Many researchers have called an immediate attention to at- tend evaporative emissions. Control strategies of various countries and their effectiveness are reviewed in this study. A very high vehicular population density has spoiled the air quality in most of the Indian cities. This work is an attempt to assess the impact of control technology adopted, vehicle fleet classification and emission regulations on automotive evaporative emission inventory. Different technological strategies and solutions are adopted and practiced worldwide to control automotive evaporative emissions. Through this study, need is identified to take concerned aspects into account before planning and execution of control strategy to manage evaporative emission inventory in India.
