What is the difference between BS4 and BS6 engine? What is difference between BS IV and BS VI? Does BS6 engine gives more mileage?
- The BS6 vehicles are over 50% less polluting than the BS4 vehicles.
- With the BS-6 standards, the NOx emission rate can come down by approximately 25% in the case of petrol engines and 70% in the case of diesel engines. The cancer-causing particulate matter emissions from the diesel engines will also come down by 80%.
The major objective of the BS-6 engines is to reduce the sulphur content in emission, as the intake of sulphur is very harmful to health (especially cause’s respiratory issues) in the long term. BS 6 fuel has lower sulphur content than the BS-4 fuel.
Some of the advantages of using BS-6 engines are:
- it is eco-friendly
- it is more refined
- more cleaner
- decreases the atmospheric pollution and improves the air quality
- it is equipped with fuel infusion resulting in better throttle response & fuel efficiency
- It mandates the installation of Selective Catalytic Reduction (SCR) technologies and Diesel Particulate Filters (DPF) inside the engine to reduce the emission of soot from the vehicle.
- OBD (on-board diagnostics) and RDE (Real Driving Emission) is the mandatory feature for all the BS-4 vehicles, and they are used to monitor the real-time emission from the exhaust gases of the vehicle.
- BS-4 fuels contain 50 parts per million (ppm) sulphur, but the BS-6 grade fuel consists of only 10 ppm sulphur content.
