Considering BS-IV Trucks? Consider BharatBenz
Published On Feb 02, 2017
On April 1, 2017, India will awaken to a new breed of trucks, buses and other vehicles, efficient enough to complete the desired tasks of transportation without polluting. A lot of us may not be aware of the fact that India has many a times been called as an irresponsible country that dumps millions of tons of carbon footprint in the environment. And as our country enters BS-IV emission norms stage for the commercial vehicles that ply in the country, the universe will know India as a nation which is not only powerful, but also knows how to care for the mother nature as well.
But, to be able to attain the ultimate goal of less pollution and more efficiency, we would have to be careful while choosing the BS-IV commercial vehicles because BS-IV vehicles are not only less polluting, but also expensive. Why commercial vehicles? Because the world sees commercial vehicles, especially trucks and buses, as the main culprits polluting the environment.
On that note we hope you know a bit about the BS-IV emissions norms and technologies that are helping Indian truck and bus makers achieve these advanced emission standards. Such information can certainly help you take a decision, while choosing the CV brand you would want to buy a BS-IV vehicle from. Let’s take a look at the two technologies that are used in the BS-IV commercial vehicles and check if all brands use them equally.
What is EGR and SCR?
EGR: Exhaust Gas Recirculation denotes recirculation of air internally in order to purify it before throwing it out of the exhaust system.
SCR - Selective Catalytic Reduction converts the harmful nitrogen oxide into harmless nitrogen, water and steam.
Do all brands use EGR and SCR Technology?
Not all truck makers use EGR and SCR technology in their trucks. Though major CV brands use EGR in all their trucks, they only use SCR in premium trucks. Only BharatBenz, a subsidy of Daimler, which also manufactures Mercedes Benz trucks, has endowed its complete truck range with SCR technology.
How will these technologies matter?
We have already explained about the difference in both the technologies, now let us explain the impact these will have on the overall business and life of new BS-IV trucks. Trucks endowed with EGR technology, because of this technology's crass behaviour towards the engine, will eventually lead to lesser profits and higher maintenance costs. EGR simply works by recirculating a portion of engine's exhaust gas back to the engine cylinders. Thus, resulting in less fuel efficiency and engine efficiency.
Trucks with SCR technology on the other hand, will lead to more profits and better vehicle life. SCR works by starting a chemical reaction that converts nitrogen oxides into nitrogen, water, tiny amounts of carbon dioxide (CO2) and natural components of the air we breathe. DEF, Diesel Exhaust Fluid used during the reaction is a non-toxic fluid composed of purified water and automotive grade aqueous urea (Aqueous Urea Solution, AUS32). Remember, SCR is neither harsh on nature, nor on the engine.
The decision taken by the Government of India is indeed a magnificent one. After all, it will only lead towards a better environment for our kids and coming generations. But we would have to choose intelligently to be able to minimise the overall cost we pay for the same. Buying BS-IV trucks such as the ones sold by BharatBenz, endowed with better technologies like SCR, is a far better decision than buying trucks that comply with BS-IV emission norms but are not fit for long operations, as they will only lead to more loss than profits.
It’s a plain fact that consumers buy trucks for generating revenue out of the transport business industry. And if that profit gets killed just because of a wrong technology, the anger outburst is sure to cast a pall on the new emission norms policy!
