As we are on a crucial point of environmental awareness and management, the automotive industry also working on methods to provide an environmentally friendly option like EV’s and hybrid vehicles. But this step taken by the automotive industry alone can’t bring about the change that the environment and we human beings are looking for. Seeking the solution the government of India also started implementing stricter emission norms (BHARAT STAGE EMISSION NORMS).
What is Bharat stage emission norms?
This Bharat stage emission norm was first implemented in India in the year 2000 and this was instituted by the Government of India to regulate the output of the air pollutants from the internal combustion engines in motor vehicles. This step was taken by the government to keep the pollution in check. With the progression of time government made the law stricter by introducing the later versions of these norms like the BS2 in 2005, BS3 in 2010 and rolling out BS4 norm in 2017 which is still applicable and followed by the automotive industry to keep the pollution level in check. These norms are unified and should be followed by every automotive manufacturer and produce their vehicles according to these norms. The basic purpose of these norms is to limit the release of the pollutants such as nitrogen oxides, carbon monoxide, particulate matters, hydrocarbons and the Sulphur oxides from the vehicles.
What is the Bharat Stage 6 (BS6) norm?
The awaited Bharat stage 6 (BS6) is the sixth mandate for the vehicular emission standard that will bring much-needed changes in the Indian Automotive industry with respect to the pollutant emission in the country.
The BS6 norm is a much stricter version of the BS4 norm which is being implemented to help the country in its fight with air pollution. At the current state, India is lagging behind all the developed countries and their advanced automotive technology by at least 5-10 years. The purpose of introducing the BS6 norms was to let India come to at par with other developed countries and close the technological gap between them.
The BS6 norm includes many technological improvements under the hood, most important being the reduction of Sulphur traces in the fuel by 5 times. An announcement was made by the government of India in 2016 that said: “India is skipping the BS5 norm and will adopt the BS6 norm by 2020”.
Advantages of BS-4?
· The norm will bring a change in the fuel, as the BS6 compliant engine requires BS6 fuel.
· A most important difference between BS6 fuel and the outgoing BS4 fuel is that the BS6 fuel contains 5 times fewer Sulphur traces (10 parts per million) compared to BS4 (50 ppm).
· The Particulate Matter (PM) emission will see a substantial decrease of 80% in diesel engines.
· Nitrogen oxides emission will come down by approximately 25% for the petrol engine and 68% for the diesel engines.
· For the first time emission can be measured in real-world conditions and not just under test conditions. Due to the introduction of RDE (Real Driving Emission).
· On-board diagnostics (OBD) will become mandatory for every vehicle, and it will help monitor the pollution caused by the vehicle in real-time.
What are the challenges regarding BS-6?
Although it sounds all good for the environment and people, it is a herculean task for manufacturers to make their vehicles compliant for the BS-6 norm. The major problem faced by the manufacturers is selling and clearing their BS-4 stocks before 1st April 2020.
Confusion regarding BS-6 fuel
Can BS4 cars run on BS6 fuel?
People having petrol cars don’t need to worry too much because BS4 petrol and BS6 petrol have very little difference in chemical composition. So the petrol BS4 car will work fine with the BS6 petrol.
Now comes the tricky part, the vehicles with diesel engines in it. Using BS4 fuel in a BS6 vehicle will cause a lot of problems. The BS6 engines are re-engineered with sophisticated electronics and redesigned exhaust system, and included DPF (Diesel Particulate Filter) and SCR (Selective Catalytic Reduction). The BS4 fuel contains a high percentage of Sulphur particulate, so using BS4 diesel fuel will end up clogging the diesel particulate filter and thus affecting the fuel efficiency of the vehicles.
Impact on buyers
Now comes the major and most affecting part of that all the buyers of the market are waiting for “The impact of these norms on the pricing of the cars”. As we discussed earlier shifting to the BS6 norm is quite an expensive affair for the automotive manufacturers and eventually, these additional expenses will be passed down to the customers. Some of the analysts also think that shifting to BS6 norm will soar up the car price by 10% – 15% and the BS6 compliant fuel will be much more expensive than the current BS4 fuel.
But all said and done the, one thing is for sure that shifting to BS6 will be a giant leap towards a better and much more environment-friendly atmosphere for better tomorrow.
