Do we need BS revision?
According to the WHO report, 7 Million peoples were dying due to the polluted air. As per the WHO measures India has the 9 polluted cities out of 10 world polluted cities. In India, 1 lakhs children under the age of 5 are dying for every year and this air pollution is responsible for almost 12.6 percent of people’s death in India. The reason for the issues such as burning coal, fossil fuel burning, ploughing etc.
There are so many teams/programs are available to control the air pollution ex: To control the pollution norms in industries; National clean air program. Likewise, the number of programs are available to the respective department. Here the program to control the pollution due to the vehicle is BS stands for Bharath Stage.
BS norms is based on European emission standards. It is available from the year 2000 itself in India. BS 2 and BS3 were regulated in India in the year 2001 and 2005 respectively. In continuing the iteration now is the time to switch over from BS 4 to BS 6 by skipping BS 5 because of the horrible scenario of our environmental condition.
So, this environmental condition decides the regulation of the BS system and other programs from the Nation greenery tribunal.
Difference between the BS-IV and BS-VI
The BS regulation always tells to limit the factors/values for both the fuel as well as the engine. If we speak technically means it is difficult to understand the difference between these two regulations. So, we can discuss some common factors. In BS-VI The Particulate matter is in the fuel around the range of 20 – 40 microgram per cubic centimeter. Whereas in BS-IV fuel it is up to 120 microgram per cubic centimeter. Importantly Sulphur content in BS-VI fuel is 5 times lesser than in BS-IV fuel especially in Diesel because we are all knew that the emission of diesel is higher than the petrol. So, BS-VI stressing in diesel fuel and engine norms which doesn’t mean that the norms only for the Diesel and diesel engines.
In BS-VI engine differ from BS-IV engines which had the extra features such as OBC (Onboard Diagnostics), RED (Real Driving Emission) and SCR (Selective Catalytic Technology). These features are effectively using petrol and reduce the emission as much as possible. To know more about these features just refer to the links given below.
