Is BS6, the norms we needed?
Pollution can’t be friends with you in any way because of the harmful combination of chemicals it contains. Everyone wants to breathe fresh and pure, but no one wants to contribute a part of their attention to the environment. There is just a simple responsibility one should undergo the pollution check every period of time. This will help in checking the level of pollution you were throwing out every time. The increasing number of vehicles, the use of fuels, poor transportation system, and frequent industrialization setups are the main reason for the increased level of pollution in the country. You must have heard about various forms of pollution such as air pollution, water pollution, soil pollution, noise pollution, radioactive pollution and so on. Air pollution is one of them that caused due to the emission of harmful smoke out of the vehicle engine that drivers don’t really bother about. It contaminates the air with harmful gases, dust, smoke that we inhale. Not only human beings, but it also affects plants and animals.
WHAT WORSE AIR POLLUTION CAN DO TO THE ENVIRONMENT?
- Deterioration of the environment: The increase in air pollution severely affects the environment and leads to degradation. The raised amount of pollution encourages the level of CO2 in the atmosphere which can restrict sunlight to reach the earth which is essential for living creatures on earth. The combination of gases such as sulfur dioxide and nitrogen oxide can cause disturbance to the various species on earth.
- Affects human health: Humans need oxygen to live, but if it gets contaminate how will they survive? The deterioration level of air leads to various respiratory diseases in humans such as asthma, bronchitis, lung cancer, throat inflammation, cardiovascular issues, skin irritation, and uncountable health issues.
- Global warming: This word ‘Global warming’ has become familiar to everyone these days because it’s another threat of earth due to increased pollution especially CO2. Every new vehicle comes on the road lead to pollution in the environment. Global warming is responsible for polar ice melting gradually that increases the sea level and cause danger to the people living near coastal areas.
- Harm to agriculture: The increasing level of pollution due to harmful gas discharge can lead to infertile land that can hit farmers hard work very badly. The effort farmers put in cultivation will all go in vain. You eat well because they produce good, keep this in mind.
Now, you can imagine how vigorously emission of smoke from your vehicle engine can damage the livelihood of people residing on every corner of the globe. So, start a bit from your side and contribute to the eradication of pollution dissolving in the air.
WHAT IS BHARAT STAGE EMISSION STANDARDS BS4 AND BS6?
Under the Ministry of Environment, Forest and Climate Change, the Central Pollution Control Board sets the pollution emission standard and the timeline for implementation and regulation for the output of air pollutants from internal combustion engines and spark-ignition engines equipment in a motor vehicle.
Before you start digging out about the engine type and pollution emission BS4 and BS6. Let’s know little about how it starts? The first emission introduced in the year 2000 with the name ‘India 2000’. In the year 2005 and 2010, BS2 and BS3 were introduced. And, then 2017 came up with emission norm BS4. Every motor vehicle has to go through compliance with the regulation if manufactured after the implementation of the pollution norms. In 2016, the Indian government has announced to skip BS5 norms and take on BS6 norms by 2020. The sale and registration of motor vehicles conforming the standard emission 6 are going to be banned from 1st April 2020 according to the Supreme Court judgment. This important step was taken to control the heavy pollutant emission facing by the people became worse around 2019. The adoption of norm BS6 is introduced to bring down pollution levels.
POLLUTION EMISSION NORMS BS4 VS BS6
- BS6 emission standard is the sixth emission norm in the sequence in terms of reducing pollution as compared to retiring the BS4 emission standard. BS4 and BS6 are the assigned emission norms that set the maximum allowable levels of pollutant releases from a motor vehicle engine exhaust.
- The BS6 norms vehicles required to emit nearly 60mg/km of NOx (nitrogen oxides) emission, not more than that. Whereas, it was 80 mg/km in the case of BS4 norms. Though, the particular matter (PM) limit has also been capped at 4.5 mg/km in petrol engines.
- In the case of diesel cars emission norms, it’s way strict. NOx emissions should go down from 250 mg/km to 80 mg/km, HC+NOx emission must go down from 300 mg/km to 170 mg/km, PM emissions from 25 mg/km to 4.5 mg/km.
- The level of sulfur and nitrogen oxide content in fuel plays a significant role. BS6 fuel has lower sulfur content than BS4 fuel. The sulfur content in BS6 fuel is five times lower (10 ppm) as compared to sulfur content in BS4 fuel (50 ppm). And, the nitrogen oxide level for the BS6 diesel engine and petrol engine will be brought down by 70% and 25%.
- After BS6 norms come in effect from 1st April 2020, BS6 fuel will start dispensing across all petrol pumps in the country. You can even use BS6 fuel in BS4 or older cars without any trouble.
- Sulfur in fuel helps in proper lubrication inside the engine and burn more efficiently. BS6 contains lower sulfur than BS4 fuel with additives that imitate the lubricating properties of Sulphur.
- Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) came up with a role in BS6 norm, whereas, it wasn’t available with BS4.
- With the introduction of BS6 emission norms, Real Driving Emission (RDE) will also be implemented to measure a vehicle’s pollutant emission in real-time conditions. It was not paired with BS4 emission norms.
- Onboard Diagnostic (OD) feature is another change that came up with BS6. It wasn’t introduced with BS4.
- A vehicle that has BS6 compliant engine require to fill with BS6 fuel. It won’t adhere to BS6 norms if someone with a BS6 engine uses BS4 engine fuel. Whereas, the emissions will be increased if a vehicle with BS4 fuel engine uses BS6 engine fuel.
