In the wake of ever-rising air pollution levels in India, the Central Pollution Control Board (CPCB) has established regulations known as the Bharat Stage Emission Standards. These emission standards have been made compulsory by the Government of India to keep pollution levels in check by controlling air pollutants emitted by the internal combustion engine of vehicles.
Before we get to know the differences between BS6 and BS4 engines, let us learn what is Bharat Stage 6 and what is Bharat stage 4.
What Is Bharat Stage 6?
The Bharat Stage Emission Standards (BSES) has recently brought in Bharat Stage 6 or BS6, the sixth iteration of the vehicular emission norms. With the implementation of BS6, India’s emission norms will become equivalent to those of developed countries.
What Is Bharat Stage 4?
The Bharat stage 4 or BS4 emission norms were introduced in 2017. According to the Bharat stage 4 emission criteria, 50 parts per million sulphur content was permitted as opposed to 10 parts per million mandated now by the BS6 norms.
Differences Between the BS6 and BS4 Engine
The BS6 emission norms are stricter than the BS4 criteria. A vital difference is that the BS6 engine requires fuel containing five times lower sulphur traces as compared to the BS4-fuelled engine. Also, Nitrogen Oxide (NOx) levels under BS6 norms has been brought down by 70% for diesel and 25% for petrol engines.
BS6 compliant petrol cars are designed to emit no more than 60mg/km of NOx emissions, and the particulate matter (PM) limit is at 4.5mg/km. Furthermore, the emission norms for diesel engines are more stringent; NOx emission is required to be reduced from 250mg/km to 80mg/km. The PM emission is to go down from 25mg/km to 4.5mg/km, and the HC and NOx emissions must be decreased from 300mg/km to 170mg/km.
Under the BS6 norms, Onboard Diagnostics (OBD) will become mandatory for all vehicles. Another significant change is the introduction ofDiesel Particulate Filter (DPF) andSelective Catalytic Reduction (SCR) in diesel engines. Additionally, Real Driving Emission (RDE) will be introduced that will measure the vehicle’s emission in real-world conditions.
The Best Option for Car Owners
Recently, the Government mandated that no Bharat Stage 4 vehicle will be sold after April 2020. In this situation, it is ideal to purchase cars that are compliant with BS6 norms. But, it may be difficult afford a swanky new BS6-compliant vehicle without exhausting your savings. An outstanding alternative to a new car is to purchase a second-hand BS6-compliant vehicle with a pre-owned car loan. Availing used car loans to buy used cars is a smart way to adhere to the Bharat stage emission standards without burning a hole in your pocket.
