What are BS-IV and BS-VI? What is the difference between them? Do you know the norms for BS-VI? No? It’s okay! We are here to take you to this world of automobile technology, where government and automobile companies are endeavouring hard to bring down pollution levels in India. Ministry of Road and Transport associated with the Government of India have commended to implement BS-VI norms while manufacturing and selling of four-wheelers as well as two-wheeler vehicles. They revised the date from 1 April 2018 to 1 April 2020, as it needs considerable time to adopt new norms or regulations. 


What is the difference between ‘BS-IV’ and ‘BS-VI’?

               Bharat Stage Emission Standards (BSES) regulate the output of harmful emissions, such as, Hydrocarbon and Nitrogen oxide. BS-IV was introduced in 2017 and then the government jumped directly to BS-VI by skipping BS-V as the situation was getting worse day by day. As per the regulations of BS-VI, it is expected that air pollution will be reduced by 80%-90% compared to the BS-IV version. 

               The level of sulphur content will also be dragged down from 50 ppm (in BS-IV) to 10 ppm. In BS-VI compliant diesel and petrol vehicles, Particulate Matter (PM) emissions will be modified to 4.5mg/km. Not only this, but BS-VL diesel-based vehicles will also emit 170mg/km of Hydrocarbon (HC) and Nitrogen Oxides (NOx) where diesel cars with BS-IV engines emit 300mg/km which makes a huge difference.

How the prices are going to manipulate for ‘BS-VI’?

                  On the other hand, when we think about the prices, the prices of BS-VI petrol vehicles will increase by Rs.10,000-Rs.20,000 and in the case of diesel vehicles, it can be increased by as much as few lakhs or more.

Can a ‘BS-IV’ vehicle run on ‘BS-VI’ fuel?

                   Now the main question arises, Are BS-IV vehicles compatible for BS-VI fuel? The answer is YES! People are concern about their BS-IV engines as, they think, BS-VI fuel will have adverse effects. But, in the case of petrol vehicles, BS-IV cars can run on BS-VI fuel. The deflated amount of sulphur in the new upcoming fuel reacts with nickel and acts as a lubricant in the fuel system of the vehicle. It helps to run BS-IV engines on BS-VI fuels easily! Also according to the recent reports, BS-VI fuel will contain additives which will lead to maintaining the same lubricity of the existing BS-IV fuels. Therefore, BS-VI fuel will not have any adverse effect on BS-IV engines. 

The future effects of the ‘BS-VI’ vehicles 

                 In conclusion, the implementation of BS-VI regulation in India will affect the economy in several ways. There are many challenges also. But it is a necessary measure to be taken as many cities in India are threatened by the increasing levels of air pollution.

Research tells us that, in India air quality is affecting immensely by the harmful emissions exhaled by the vehicles. To adopt the massive change like BS-VI engines automobile sector have to change their strategies. This process is very expensive cost-wise. Therefore, the future economy is going to hit by this change. But surely, it will be beneficial for the coming generations. Be ready for the change!
