Reducing pollutant emissions and fuel consumption in 2- and 3-wheelers in India: A technical assessment

Motorcycle sales in India have been growing at double-digit rates, and recently passed the million-vehicle-per-month mark. With annual sales five times those of passenger cars, motorcycles dominate the nation’s on-road passenger vehicle fleet. Meanwhile, three-wheelers, which play a critical role in providing point-to-point as well as feeder service in India’s urban and semi-urban areas, are on track to surpass half a million annual sales. Given their importance to personal mobility in India, reducing emissions and fuel consumption from these vehicles is a key goal for health, environmental, and energy policy.

The ICCT recently released a study of the technical and regulatory pathways toward that goal, authored by N. V. Iyer. The report surveys engine technologies and after-treatment systems used to meet current emission standards (Bharat Stage III), and the technical options for reducing emissions further to meet the proposed Euro 4/5/6 equivalent limit values.

It also reviews numerous alternatives for reducing fuel consumption, such as improved engines and other subsystems and control-system optimization, and examines ways to address the neglected areas of durability requirements, cold-start emissions, evaporative emissions, and on-board diagnostic systems. Finally, the study offers policy recommendations for improving in-use vehicle compliance testing and fuel and lubricant quality.

This webinar, presented Mr. Iyer, offers Indian policy makers, industry analysts, and other audiences the opportunity to engage directly with the author of this definitive overview of one of the crucial issues in Indian transportation and environmental policy today.
