BS4 vs. BS6 Engine - Know This Before You Buy A Bike Insurance
BS4 vs. BS6 Engines: Key Differences to Consider Before Buying Bike Insurance
To control the rising air pollution in India, the Indian Government introduced the Bharat Stage or BS norms to reduce emission levels. In 1999, the government made it mandatory for all vehicles to comply with the BS norms, which were similar to the Euro-I standards. The first emission control norms were introduced in India in 2000.
BS4 & BS6 engines are part of BS norms, and here we will discuss the difference between BS4 & BS6 engines.
What Is A BS4 Engine?
The Bharat Stage Emission Standards (BSES), which is the governing organization for emissions from all types of vehicles in the country, introduced the first emission norms with the name ‘India 2000’ in the year 2000. BS2 and BS3 were introduced in 2005 and 2010, while BS4 norms came into effect in 2017 with stricter emission standards or norms.
The laws included emission-related adjustments such as tailpipe emissions, Electronic Control Unit (ECU), ignition control, etc. The most noticeable modification was the AHO (Automatic Headlamp On), which is one of the BS4 requirements that addressed the safety component of the new emission standards.
What Is A BS6 Engine?
The BS6 emission standard is the sixth generation of the emission standard, and it represents a significant improvement in pollution reduction over the previous BS4. This is also due to the BS5 (BSV) being skipped in order to migrate to stronger emission standards.
Key Difference Between BS6 And BS4
The following are the most significant differences between BS4 and BS6 pollution emission standards:
Particulars |
BS6 |
BS4 |
Nitrogen oxide (NOx) emissions |
The maximum allowable limit of Nitrogen oxide (NOx) emissions from a petrol vehicle is established at 60 mg per kilometer by BS6. |
The maximum allowable limit of Nitrogen oxide (NOx) emissions from a petrol vehicle is established at 80 mg/km under BS4 standards. |
Hydrocarbon+NOx emissions |
In diesel cars, BS6 standards limit hydrocarbon+NOx emissions to 170 mg/km |
In diesel cars, BS4 standards limit hydrocarbon+NOx emissions to 300 mg/km |
Harmful Gases |
BS6 engines exhaust less volume of harmful gases (nitrous oxide, carbon dioxide, and other greenhouse gases) |
BS4 engines exhaust more volume of harmful gases (nitrous oxide, carbon dioxide, and other greenhouse gases) as compared to BS6 |
Combination of hydrocarbon and NOx |
It has declined by 43% in the BS6 diesel engine exhausts. |
The combination is comparatively higher in BS4 than BS6 |
Volume of Particulate Matter |
The BS6 engines running on BS6 fuel produce 50% less the volume of Particulate Matter (both PM2.5 and PM10)
|
BS4 engine produces more the volume of Particulate Matter in compare to BS6 |
Impact Of Vehicle-Generated Air Pollution On The Environment
Air pollution has a high impact on the air quality index (AQI), and due to this, multiple health issues such as respiratory and heart ailments, cancer, throat and lung infections, etc., also have an impact on the environment in the following ways:
- Global Warming
- Contamination of air, soil, and water
- Acid rain and smog
- Exhaustion of fossil fuel, the source of petrol and diesel.
The Benefit Of BS6 Engine Over BS4 To The Environment
· BS6 norm helps the environment by reducing air pollution as with more sulfur content; motor vehicles emit toxic sulfur dioxide gas in the air. In the BS6 engine, there is a reduction in sulfur content.
· In the BS6-grade fuel, there is a steep decline (50% decline compared to BS4-grade fuel) in the volume of Particulate Matter (PM2.5 and PM10). PM2.5 is a dangerous pollutant that causes lung cancer.

Conclusion
The government of India has taken a great initiative to reduce pollution and save our environment; however, it is also the duty of citizens to support the government in this initiative by ensuring that buying new two-wheeler vehicles does not substitute BS6 norms.
