What is Bharat Stage 6, Why It Is Using In New Cars and Two Wheeler’s?

The automotive industry, which has been seeing one of the worst slowdowns in history, is set to make a transition towards BD 6 emission standards. This will come into effect from April 1, 2020. Bharat Stage will be the new emission standard which all the vehicles need to adhere to. The cars which do not comply with the Bharat Stage 6 emission standards will be seized from April 1, 2020, as per the declaration given by Supreme Court on October 24, 2019.

Finance Minister Nirmala Sitharaman has also declared that the vehicles with BS 4 emission standards can be purchased till March 2020, and remains operational till their registration period is completed.

Bharat Stage Emission Standards is a governing body that regulates the pollutants emitted by a vehicle in the country. The pollution control board sets the standards for regulating emissions in India. The emission standard was first introduced in the year 2000, and it was named as ‘India 2000.’ Bharat Stage 2 and 3 were introduced in the year 2005 and 2010, respectively. There was a gap of 7 years before introducing the Bharat Stage 4 in 2017.

Bharat Stage 6 will be introduced in April 2020 to ensure that the pollution is under control and that is the reason Stage 5 was skipped.

Difference Between Bharat Stage 4 and Bharat Stage 6

Bharat Stage 4 and stage 6 are the emission norms that decide the maximum pollutant levels that can be emitted from a four-wheeler or a two-wheeler. However, the policies of Bharat Stage 6 are stricter compared to the Bharat Stage 4. Manufacturers need to consider the Bharat Stage 6 emission levels and design the cars and bikes accordingly for better safety standards.

Diesel Particulate Filter: The Diesel Particulate Filter is a new emission norm being introduced with the Bharat Stage 6. This was not present in the Bharat Stage 4 emission norm.

Real Driving Emission: This is another new norm being introduced with the Bharat Stage 6. This norm helps to measure the real-time emission of the vehicle against the laboratory condition.

Onboard Diagnostics is another new norm for Bharat Stage 6, and it is mandatory for all the vehicles.

Change In Fuel: This is another major update with the Bharat Stage 6 vehicles. Cars and bikes that come with BS 6 engine cannot run on Bharat Stage 4 fuel. Similarly, a BS 4 engine if it tries to run on BS 6 fuel, then it will emit more pollutants and also take a hit.

The sulphur and Nitrogen Oxide content emitted by the vehicles is another major upgrade in the BS 6 engines. The sulphur traces emitted by BS 6 engines is 5 times lesser than the BS 4 engines. Also, the Nitrogen Oxide content emitted by the BS 6 engines can be lowered by 70% in the diesel engines and 25% in the petrol engines.

Can BS 4 cars run on BS 6 fuel?

If you own a BS 4 petrol car, then there is nothing much to worry about as the chemical composition of the Bharat Stage 6 and Bharat Stage 4 petrol is very similar. However, if you own a Bharat Stage 4 diesel car, then you might face a serious issue because the BS 6 engines are re-designed to emit lower traces of sulphur and nitrogen oxide. Hence the chemical composition of the diesel for BS 4 and BS 6 varies.

To reduce the pollutants released by vehicles into the environment, the government has taken this measure. So, it is advisable for the diesel car owners not to fill BS 6 fuel in their BS 4 cars, as it might damage their vehicle. However, the BS 4 petrol car owners will not face any issues due to the similar chemical composition of BS 4 and BS 6 petrol.
