​This is What You Need to Know before BS-IV Norms Kick in!

Published On Mar 24, 2017By Mukul Yudhveer Singh

There is no doubt in the fact that truck prices will increase significantly, once the new emission standards are implemented. Experts believe that the prices will shoot up by anything ranging between 5 to 20 percent. However, the Goods and Services Tax, scheduled to take final form starting July 2017 may bring some relief for consumers looking forward to buy new trucks in the near future.

Presently, all the truck manufacturers in the country are busy updating their vehicle assembly lines in order to bring them at par with vehicles complying with BS-IV emission norms. Mahindra Truck and Bus division is amongst a few CV manufacturers toiling hard to keep their vehicles updated with the newest technologies.

In fact, Mahindra is not just trying to make its trucks comply with the new emission norms, but is also researching on technologies that would help transporters, fleet owners and individual truck owners save the most through its products.

Now, as the deadline for implementation of BS-IV emission norms is fast approaching, we take you through two major technologies that vehicle manufacturers in India are introducing with the range of commercial vehicles manufactured by them.

Exhaust Gas Recirculation (EGR)

EGR as explained above stands for Exhaust Gas Recirculation. This technology works by reducing the oxygen concentration inside the engine’s combustion chamber. And due to the reduced oxygen concentration levels, the amount of Nitrogen Oxide gets deduced as well, resulting in lesser NOx emissions.

The air to be exhausted is circulated inside the engine a couple of times before being emitted out of the vehicle. A number of auto enthusiasts are of opinion that the EGR technology has the potential of reducing a vehicle’s life in the long run. They have argued that recirculating exhaust air inside the engine compartment, and reducing the Oxygen concentration inside the vehicle can leave the engine overworked and hence lead towards poor vehicle life.

What is more worrying for the Indian trucking community is the fact that most CV makers in the country are equipping the trucks manufactured by them with the same technology. This technology might just make things worse for truck operators in India.

Selective Catalytic Reduction (SCR)

Selective Catalytic Reduction (SCR) technology reduces emissions by converting harmful Nitrogen Oxide into harmless Nitrogen gas, steam and water. The incorporated SCR system injects a vehicle’s exhaust route with a liquid agent via a special catalyst. This liquid agent triggers a chemical reaction inside the exhaust route that turns harmful Nitrogen Oxide into water, steam and Nitrogen gas before they are thrown out of the exhaust pipe.

The advantage associated with the use of SCR comes in the form that all the chemical reactions take place outside the engine chamber, leaving no room for any kind of negative effect on the engine or vehicle life.

Though all the automakers in India are using SCR in the top end trucks manufactured by them, Mahindra Truck and Bus Division is among only a few CV makers who have decided to make use of SCR technology in all the commercial vehicles manufactured by them.

Now that you know about the two major technologies being used by CV makers in India, we hope you will be able to take informed decisions before buying new trucks or other commercial vehicles. We believe that the decision of incorporating SCR in all its commercial vehicles taken by Mahindra & Mahindra is indeed a bold move.

While most automakers may have been thinking about reduced mileage of trucks once BS-IV emission norms kick in, M&M truck & bus division might just have taken the lead on this front.

M&M is actively promoting the “mileage guarantee” in their Blazo range.

Ajay Devgun, the brand ambassador for Mahindra Blazo, can be seen in this latest TVC talking about it.
