Abstract:
Light Duty Vehicles (LDVs), typically with engine displacement volume of less than 1.5L are an integral part of the India’s automobile sector as they are one of the most preferred means of transportation in rural as well as urban India. This market has always been on the rise as a result of rising population, growing commercialization, increasing commercial activities, etc. which are all contributing to the increased demand for intra city transportation. The passenger LDVs such as the three wheeler segment dominates the market as the need for affordable passenger commutation is higher than the need for goods carriage within a city.With BS VI norms slated to be implemented in 2020, it becomes imperative to understand, plan and work out strategies to meet these norms effectively on the Indian roads & actual Indian driving behavior, especially for these LDVs. This paper discusses in detail, the various concepts and combinations of after-treatment options for LDVs, comprising of coated / uncoated particulate filters, with NOx reduction technologies selected from LNT, NSC, NSRC & SCR or their combinations to comply with BS VI norms in India. The paper also discusses the importance of well-coordinated actions between engine management system, ECU controls, sensors & after-treatments systems, to achieve the overall goal of meeting BS VI norms.
