Tata Motors has announced its readiness of SCR (Selective Catalytic Reduction) and EGR (Exhaust Gas Recirculation) technologies for BS IV engines powering its range of commercial vehicles.
EGR technology, which helps reduce NOx emissions from the engine and adopted by Tata Motors in 2010, will continue to power its small-to-medium category of CVs with engine power up to 180hp. Tata says it has developed EGR technology in-house and it covers the entire range of Tata engines including the new-generation 3-litre and 5-litre engines
Tata Motors has, since 2014, used the globally proven SCR technology for its medium and heavy-duty CVs ranging from 130hp to 400hp. Tata Cummins, a JV between Tata Motors and US-based Cummins Inc, has developed these engines. SCR technology allows engine to operate at more optimal combustion temperature providing better power, fuel efficiency and lower NOx and particulate matter generation
According to Tata Motors, it has “perfected both the SCR and EGR technologies on a wide range of vehicles that have been sold to customers within India as well as abroad.”
Speaking in Mumbai today, Ravindra Pisharody, executive director – Commercial Vehicles, Tata Motors, “Tata Motors has led technology changes in the Indian commercial vehicle industry over the last six decades. 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.”
While EGR is a relatively low cost, simple, and easy to integrate technology, SCR can be scaled up further to meet upcoming BS VI norms.
