India is closing the gap to regions with the most stringent exhaust emission regulations by introducing Bharat Stage VI emissions legislation in advance. For passenger car diesel engines, this results in the need of exhaust aftertreatment regarding particulates and nitrogen oxides, which is intended to contribute to improved air quality in urban areas. Other than in Europe, the traffic situation and system costs favor systems based on a lean NOx trap for this purpose, as Graz University of Technoloy and AVL show in this article.
India is an emerging market for passenger cars and the annual growth rate for new registrations accounts for 9 %. In 2017, 3.2 million passenger cars were registered, making India the third largest Asian key market, only outranked by China and Japan [1, 2]. In the last decade, India has been among the regions with the highest diesel shares. The diesel peak, which was based on the favorable fuel prizing, was reached in 2012/13, when more...
