After the announcement made by the Supreme Court of Indian regarding the ban of sale as well as registration of new vehicles that are compliant with BSIII emission norms, the automotive industry, particularly the commercial vehicle sector took a jolt due to the extra BSIII inventory. Most manufacturers have managed to recover the loss including Tata Motors, which has also upgraded its entire lineup to BSIV compliance. All engines will now be equipped with EGR (Exhaust Gas Regulation) and SCR (Selective Catalytic Reduction) in order to reduce tailpipe emissions along with achieving better fuel efficiency figures. This technology can be scaled up further to comply with BSVI emission norms that are expected to come into effect by April 2020.

The SCR process converts harmful NOx gases to nitrogen and water using a Diesel Exhaust Fluid (DEF) which is added to the exhaust stream. This fluid decomposes to form Ammonia which reacts to the NOx gases and the end product is nitrogen and water. The engine range that has gone through this upgrade are the ISB5.9 BSIV EGR: 160 hp to 180 hp, ISB5.9 BSIV SCR: 130 hp to 230 hp, ISB6.7 BSIV SCR: 230 hp to 300 hp and ISB8.9 BSIV SCR: 400 hp. The ISB5.9 BSIV Cummins B5.9 BSIII mechanical engine which was the first unit of its kind to comply with BSIII emission norms.

Ravindra Pisharody, Executive Director, Commercial Vehicles, Tata Motors said, “Tata Motors has led technology changes in the Indian commercial vehicle industry over the last six decades.We have always endeavoured to develop products and introduce future technologies, ahead of regulations and have played a proactive role in regulation compliance. Tata Motors continues to be at the forefront of meeting emission regulation, driven by our concern for environment and health impact. Introduction and adoption of EGR and SCR technology in 2010 and 2014 respectively reiterates our capabilities with regard to introducing future technologies. Because we strongly believe in offering the best-suited technology for various applications, we will offer both SCR and EGR technologies on BS IV solutions. This will not only meet regulatory requirements for emission norms but also optimise the total cost of ownership, ultimately benefitting our customers.”
