Emission Control Options and Optimization for BSVI Heavy Duty Diesel Applications 2017-26-0120

The legislative decision to accelerate the implementation of regulations requiring advanced emissions control in India have accelerated the need to advanced emissions control systems. Particulate filters and NOx abatement technology will be needed to meet the new BSVI standards. Integration of these emission control technologies into engine design poses new challenges to the Indian Heavy Duty Diesel Truck Industry. Each new market that implements advanced emission regulations faces challenges that are unique to the local regulation, the local vehicle design, and the local operating conditions. This paper will review the technology options available for BSVI, their strengths and weaknesses, and potential system designs. Additionally this paper will review how critical design factors such as filter regeneration conditions, duty cycle temperatures, and urea injection can affect the system design and catalyst selection.
