All You Need to Know About BS-VI Fuel and How it Helps Reduce Pollution

In 2020, India took a significant technological leap to make the country's auto industry more environment-friendly. The announcement of the BHARAT Stage-VI fuel came as no surprise, especially after rapidly increasing pollution levels.

If you thought the BS-IV norms were too much, wait until you hear all about the BS-VI emission norms. But, what changes do the BS-VI norms bring, and how can it curb pollution? Well, this article will demystify all the key questions surrounding the BS-VI emission regulations.

How Will Automakers Switch to BS-VI?

It is one of the burning questions! Typically, automakers will take two-pronged routes to make cars BS-VI complaints. It involves engine work and a round of after-treatment. Manufacturers will include fuel injector design and enhanced combustion chamber in the in-cylinder measures. As a result, cars can enjoy finer atomization of fuel.

The cars will also employ a Lean NOx Trap (LNT) or SCR system to handle high levels of NOx in diesel engines. On the flip side, the exhaust treatment system will curb pollutants like NOx and PM.

How is BS-VI Different From BS-IV?

Thanks to the updated Bharat Stage emissions norms, the NOx level will reduce drastically by 68% for diesel engines and 25% for petrol. The reduced NOX levels will also be achievable through an 82% reduction in Particulate Matter levels. Moreover, for the first time in the Indian auto industry, petrol engines will attract regulation for particulate-matter production.

Between the two norms, there is also a difference in terms of Nitrogen Oxide and Sulphur content. It is worth mentioning that the BS-VI engines emit five times lesser traces of sulfur than B-IV.

The BS-VI norms also led to the introduction of Selective Catalytic Reduction (SCR) and Diesel Particulate Filter (DPF). Unlike the BS-IV criteria, BS-VI makes Onboard Diagnostics mandatory for all cars and vehicles.

What Difference Will BS-VI Make on Cars Costs?

Auto experts have already predicted an incoming surge in vehicle costs. Upgrading the diesel vehicles according to the BS-VI norms will incur more charges. Naturally, automakers will pass on this cost to the consumers. But, this does not mean that cars prices will skyrocket.

The range of diesel cars might get dearer by up to Rs. 1 lakh. On the other hand, you can expect a hike of Rs.10,000 to rs.20,000 in petrol car variants.

Can a BS-IV Car Run on BS-VI Fuel?

The good news is that it is possible to run your BS-IV car on BS-VI fuel. The only minor change between the BS-VI and BS-IV fuel is reducing sulfur content. We don't think that cleaner fuel has any potential harm for BS-IV cars. 

Even in the older engines, you can expect a slight reduction of emission levels with BS-VI fuel.
