Bharat Stage Emission Standards

The central government has mandated that all vehicle manufacturers, both two-wheelers and four-wheelers, should manufacture, sell and register only BS6 (BS-VI) vehicles from 1 April 2020.

In this article, you will learn about BS4 vs BS6 norms associated with Automobiles.

✅What is bs4 (bs-iv)-

Let’s understand the former BS4 (BSIV) emission norms, engine, performance, and its significance.

The 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 most visible change was the AHO (Automatic Headlamp On).

• Low capacity motorcycles were added with more efficient carburetors and a newly added layer of the catalytic converter in the exhaust systems.

✅What is bs6 (bs-vi)-

The BS6 emission standard is the sixth iteration of the emission norm and comparatively, it’s a substantial leap in terms of reducing pollution compared to the outgoing BS4. This is also because the BS5 (BS-V) has been skipped in an effort to move to better emission norms.

•  All the motorcycles having carburetor will shift to more advanced and efficient EFI systems.

•  Electronics control the EFI system to atomize fuel inside the combustion chamber.

✅History of BSES (Bharat stage emission standards)-

• Introduced in the year 2000.

• Hey are set by the Central Pollution Control Board under the Ministry of Environment and Climate Change.

• Objective: To keep the air pollutants emitted by the internal combustion engine of vehicles under control.

• They are based on European (EURO) emission standards.

• Bharat Stage (BS) emission norms were first brought into effect in 2000 under the head “India 2000”. This was followed by BS2 in 2001 and BS3 in 2005.

✅What are difference  bs4 (bs-iv) and bs6 (bs-vi)-

• Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) is being introduced with the roll-out of Bharat Stage VI norms, which were not a part of Bharat Stage IV.   

• Real Driving Emission (RDE) will be introduced in India for the first time with the implementation of Bharat Stage VI emission norms. It will measure a vehicle’s emission in real-time conditions against laboratory conditions.  

• Onboard Diagnostics (OD) has been made mandatory for all vehicles. 

• Sulphur and Nitrogen Oxide content: Sulphur traces in BS6 fuel is five times lower (10 ppm) as compared to sulphur traces in BS4 fuel (50 ppm). Further, the nitrogen oxide level for BS6-grade diesel engines and petrol engines will be brought down by 70% and 25%, respectively. 

A BS6 vehicle using BS4 fuel will not adhere to the required emission norms due to higher levels. Hence, a BS6 vehicle has to use only BS6 fuel to achieve the desired emission levels.  

 

From 2020, when the BS6 norm kicks in, BS6 fuel will also be dispensed across the country’s petrol pumps from the same date onwards. 

✅What will happen to the existing bikes and cars-

Users of petrol cars have little to worry about compliance as there is very little difference between BS4 and BS6 fuels. However, the same isn’t the case with diesel vehicles. 

 

With BS6 fuel already available in many cities, owners of older generation cars can opt for it at filling stations.

• Buyback- Yes that’s what a company can do. Hero MotoCorp for example assured it’s dealers recently that it will buy back the unsold BS4 inventory. While Hero has been generous, others haven’t been so forthcoming.

• Scrapping- Unfortunately while a BS4 vehicle, given the present conditions, cannot be registered post-April 30, 2020, it will have to be scrapped. A dealer cannot sell the vehicle and will incur heavy losses in this method.

• A dealer can register the car or bike under his employee’s name and then sell the vehicle as a used one.

• An auto manufacturer can always take back the model, modify it according to BS6 standards, and sell it. However, if these are minor modifications, like in the case of petrol-powered cars, might not need ARAI approval

• After buying back these vehicles, the manufacturer can export them to markets that still follow the previous norms or equivalent of BS4.

✅Impact of BS-6 norms on the auto component industry-

India has traditionally been a laggard in terms of enforcing and implementing emission norms for the manufacturing sector. Indian auto industry is not an exception to this either. For instance in the capital city of Delhi, vehicles contribute 59%, 50% and 18% of the overall emissions of carbon monoxide, hydrocarbons and nitrous oxides respectively.

The move to BS-VI norms from BS-IV norms will bring down NOx emissions by 25% in petrol engine vehicle and by 68% in diesel engine vehicles. PM emissions, a major component of outdoor air pollution, are also expected to come down drastically by over 80% in diesel engine vehicles.

• Technological Upgrade and Investment

• Adoption of Technology as per Indian requirements

• More Complex, Electronic Vehicles 

 

✅Why we skipped BS-V-

This led to ,india’s emission norms now stricter than europe & japan.

In a natural progression, we would have moved to BS5 norms from the older BS4 regulations which were implemented just three years ago! And the BS6 emission norms were initially planned to be implemented in 2024.

However, we decided to skip BS5 and go ahead with BS6 – That is full four years ahead of schedule! 

So, the next time you ride your BS6 motorcycle, feel good about the fact that it is the most environment friendly, greenest vehicle in the world😃 

 

 ✅What's worse air pollution can do to the environment-

• Deterioration of the environment: 

• Affects human  health

• Global warming

• Climate change

• Smog effect

• Extinction of animal species

✅FAQs-

❓ What happens if you fill BS6 fuel in BS4 car?

☑ You can fill BS-VI fuel in BS-IV cars or older models.The BS-VI fuel has lesser sulphur; however, it contains additives which helps in the lubrication of the engine.

❓ Is bs6 more fuel efficient?

☑ The BS6 Maruti Suzuki Dzire is 7hp more powerful and more fuel efficient than its predecessor. The Dzire powered by a BS6compliant 1.2-litre petrol engine that churns out 83 hp and 113 Nm of torque.

 

❓ Will bs6 bikes increase mileage? 

 

☑ Bajaj recently launched the BS6 version of the 'Most Affordable Bike' in India. ... This engine is a BS6-compliant, fuel-injected unit which produces 7.7bhp and 8.34Nm of torque and comes mated to a four-speed gearbox. It has seen a nominal increase in mileage as compared to its BS4 counterpart.
