Understanding BS6 Norms

From 11st April 2020, India will absolutely adopt the stricter BS6 emission norms – a transition that can be termed as the largest technological bounce for the automotive sector. The shift, by skipping BS5, has now not handiest befell in record time – around three and a half of years – however additionally under outstanding pressure, as both the oil organizations and the auto enterprise labored relentlessly to prepare in time for the hard closing date of April 2020.

However, now not all automakers have controlled to make this transition fast sufficient, resulting in lots of fashions and powertrains being phased out. The implementation will results in additional expense Naturally, the speak surrounding the shift has raised many questions and left many automobile consumers flummoxed. But we’ll break it down and tell what you want to understand.

What are Bharat Stage Emission Standards?

Based on the European regulations, Bharat Stage Emission Standards (BSES) are are emission standards instituted by the Government of India to regulate the output of air pollutants from internal combustion engines and Spark-ignition engines equipment, including motor vehicles. The standards and the timeline for implementation are set by the Central Pollution Control Board under the Ministry of Environment, Forest and Climate Change.
The BSES were first introduced in 2000 and all new vehicles manufactured after the implementation of the norms have to be compliant with the regulations which are in action at the time of launch of the vehicle. Currently, we are following Bharat Stage 4 norms. The Govt. of India decided to skip BS5 and will directly implement BS 6 norms from April 1, 2020.

What is Bharat Stage 6?

The Bharat Stage 6 (BSVI) norm is the sixth mandate for vehicular emissions and a much welcome change amidst the rampant air pollution in India. BS 6 is a stricter, more restrictive norm that will give a jumpstart to India’s long battle with air pollution. With the roll-out of the BS6 norms, India will come at par with the US and European equivalent emissions norms.

What is the distinction among BS4 and BS6 emission limits?

Under the imminent emission regime, NOx levels will go down by way of 25% for petrol engines and a drastic 68% for diesel engines. The latter can also be met with the requirement of a severe 82% discount in PM ranges. And for the first time, petrol engines (with direct injection) will attract law for their particulate-be counted manufacturing.

What will be the effect of BS6 norms on the car prices?

Industry experts consider the excessive cost of upgrading diesel and petrol cars to meet BS6 norms will definitely lead to higher ex-showroom prices of the cars, however, it will not push them past the reach of clients. While it is expected that small BS6 petrol engines will cost around INR 30-50,000 more than their BS4 counterparts, the small BS6 diesel engines will now cost a whopping INR 80,000 to 1,20,000 more than their BS4 counterparts. The value by which the BS6 engines are set to get expensive is even more for the larger displacement engines. Toyota recently announced that the Toyota Fortuner and the Toyota Innova Crysta are set to get expensive by INR 2-2.5 lakhs once the BS6 norms come into action.

What make BS6 different from BS4?

Firstly, the norm will bring in a change in the fuel type as the BS6 compliant engine requires BS6 fuel. A BS6 vehicle using BS4 fuel will not adhere to the BS6 norms. The BS6 will be available all across India post the introduction of BS6 norms. However, in Delhi and NCR, BS6 fuel is already being distributed after the Govt. of India orders.
A vital difference between BS6 and the outgoing BS4 fuel is that the BS6 fuel contains 5 times fewer sulphur traces (10 parts per million) compared to BS4 (50 ppm). NOx (Nitrogen Oxide) level will be brought down by a staggering 70% for Diesel engine and 25% for Petrol Engines
The BS6 brings along a plethora of changes, most significant being the mandatory OBD (Onboard Diagnostics) for all vehicles.
RDE (Real Driving Emission) will be introduced for the first time that will measure the vehicle’s emission in real-world conditions against simulated conditions.
Introduction of DPF (Diesel Particulate Filter) and SCR (Selective Catalytic Reduction) for Diesel engines.

What is BS6 ready engine?

A Bharat Stage 6 ready engine has major modifications to its components to make it cleaner and adhere to the BS6 emission norm. Modifications like improved fuel quality composition and a DPF (Diesel Particulate Filter) and SCR (Selective Catalytic Reduction) in diesel cars are put to use to make the vehicle BS6 ready.

What are the predominant forms of pollutants?

Internal combustion engines (ICEs) are generally infamous for the manufacturing of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx). Particulate matter (PM), or carbon soot, is every other by-product of diesel in addition to direct-injection petrol engines.

Can BS4 automobiles run on BS6 fuel?

Operating BS4 vehicles on the cleanser fuel shouldn’t pose any extreme challenges because the only major distinction between BS4 and BS6 grade fuels is the significant reduction in sulphur content,which is mainly restricted to diesel. Moreover, the use of BS6 fuel may be anticipated to yield a moderate discount in emission stages even in the older engines. However, since Sulphur in diesel is used to lubricate the injectors. Lower amounts of suplhur in the diesel may lead to premature wear of the injectors.

Will BS4 vehicles be banned?

Yes, after 1st April 2020. As in line with the Supreme Court’s verdict on October 2018, registration of a new BS4 vehicle will be completely banned. The court docket has even given an ultimatum to car manufacturers to clean their antique inventory of BS4 cars earlier than the closing date. The court docket has additionally made it clear that no extension may be given to car agencies for old BS4 car inventory clearance at any cost.

Effect of BS6 norms on car performance and fuel efficiency?

Lowering environmental emissions can really take a hit on a car’s performance. A cleaner engine carries a generally slower combustion process. Adding to this, are major exhaust modifications which further bottlenecks the overall performance of the cars. Therefore, BS6 compliant cars will be down on performance. However it is worth noting that many cars still come in same state of tune, even after the transition to the BS6 norms.
