NEW DELHI: India will switch to the world's cleanest petrol and diesel from April 1 as it leapfrogs straight to Euro-VI emission compliant fuels from Euro-IV grades now - a feat achieved in just three years and not seen in any of the large economies around the globe.
India will join the select league of nations using petrol and diesel containing just 10 parts per million of sulphur as it looks to cut vehicular emissions that are said to be one of the reasons for the choking pollution in major cities.
Sanjiv Singh, Chairman of Indian Oil Corp (IOC) - the firm that controls roughly half of the country's fuel market, said almost all refineries began producing ultra-low sulphur BS-VI (equivalent to Euro-VI grade) petrol and diesel by the end of 2019 and oil companies have now undertaken the tedious task of replacing every drop of fuel in the country with the new one.
"We are absolutely on track for supplying
BS-VI fuel from April 1. Almost all refineries have begun supplying BS-VI fuel and the same has reached storage depots across the country," he said.

From storage depots, the fuel has started travelling to petrol pumps and in the next few weeks all of them will only have BS-VI grade petrol and diesel, he said. "We are 100 per cent confident that fuel that will flow from nozzles at all the petrol pumps in the country on April 1 will be BS-VI emission compliant fuel."
India adopted Euro-III equivalent (or Bharat Stage-III) fuel with a sulphur content of 350 ppm in 2010 and then took seven years to move to BS-IV that had a sulphur content of 50 ppm. From BS-IV to BS-VI it took just three years.
"It was a conscious decision to leapfrog to BS-VI as first upgrading to BS-V and then shifting to BS-VI would have prolonged the journey to 4 to 6 years. Besides, oil refineries, as well as automobile manufacturers, would have had to make investments twice - first to producing BS-V grade fuel and engines and then BS-VI ones," he said.
State-owned oil refineries spent about Rs 35,000 crore to upgrade plants that could produce ultra-low sulphur fuel. This investment is on top of Rs 60,000 crore they spent on refinery upgrades in the previous switchovers.
BS-VI has a sulphur content of just 10 ppm and emission standards are as good as CNG.

Originally, Delhi and its adjoining towns were to have BS-VI fuel supplies by April 2019 and the rest of the country was to get same supplies from April 2020.
But oil marketing companies switched over to supply of BS-VI grade fuels in the national capital territory of Delhi on April 1, 2018.
The supply of BS-VI fuels was further extended to four contiguous districts of Rajasthan and eight of Uttar Pradesh in the National Capital Region (NCR) on April 1, 2019, together with the city of Agra.
BS-VI grade fuels were made available in 7 districts of Haryana from October 1, 2019.
Singh said the new fuel will result in a reduction in NOx in BS-VI compliant vehicles by 25 per cent in petrol cars and by 70 per cent in diesel cars.
The switchover, he said, is a tedious task as every drop of old, higher-sulphur content fuel has to be flushed out in depots, pipelines and tanks before being replaced by BS-VI.
"We are confident of disruption-free switchover to BS-VI supplies across the country," he said. "What we will be supplying is the best quality available anywhere in the world. You don't have any better fuel that is supplied in any part of the world. Perhaps our BS-VI fuel will be better than equivalent fuel in some parts of the US and Europe."
India adopted a fuel upgradation programme in the early 1990s. Low lead gasoline (petrol) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, unleaded gasoline was mandated nationwide.
Similarly, BS-2000 (Euro-I equivalent, BS-1) vehicle emission norms were introduced for new vehicles from April 2000. BS-II (Euro-II equivalent) emission norms for new cars were introduced in Delhi from 2000 and extended to the other metro cities in 2001.
Benzene limits have been reduced progressively from 5 per cent in 2000 to 1 per cent nationwide. Lead content in gasoline was removed in phases and only unleaded gasoline is being produced and sold from February 1, 2000.
The octane number of gasoline signifies the improved performance of the engine. Loss in octane number due to phasing out of lead was made up by installing new facilities in the refinery and changes in refinery operation. RON (Research Octane Number) of gasoline for BS-2000 spec was increased to 88. This has over time been increased to 91.
Singh said sulphur reduction will reduce Particulate Matter (PM) emissions even in the in-use older generation diesel vehicles.

Will BS VI fuel destroy BS IV engine? We explain!

By Insights Desk - February 19, 2020


The BS VI norms will come into effect from April 1, 2020. This would mean two things: One, automakers would no longer be able to sell vehicles that do not confirm to BS VI norms; Two, oil retailers will stop selling the BS IV fuel and instead roll out the BS VI fuel.
So what happens to all the car and bikes that were engineered to run on BS IV fuel?
First, the good news. If you have petrol engine-based car or bike, don’t worry. There is very little change to chemical constitution of the fuel.
If you have a diesel car or SUV, then change in the fuel composition is significant. The ‘low sulphur diesel’ that you buy currently has 50 PPM [parts per million]. The BS VI diesel will only have 10 PPM of sulphur, which of course is much cleaner and therefore, better for the environment.
Why Sulphur Matters
Sulphur in the fuel helps works as a lubricant for injectors in a diesel engine. Diesel engines have injectors that transform diesel from a liquid state to an atomised spray which then combusts in the cylinder. Some of the fuel is actually allowed to leak to lubricate the injector as it has moving parts. [The fuel is subsequently channelled back to the fuel tank.] If you have a low level of Sulphur in your fuel, it will affect the lubrication inside injectors and damage tem over period of time.
If that happens, the fuel supply to engine will be erratic, the combustion inefficient and all this would result in higher rather than lower emissions. This in fact happen the last time India switched standards and moved to BS IV.
Diesels in Trouble, then?
Not really. The fuel companies say that they are adding alternate lubricants to make up for reduced sulphur content in the BS VI fuel. So, that should take care of the injector wear and tear issues.
What if the BS VI Fuel Rollout Gets Delayed?
While Delhi has switched to BS VI fuel already and it is certain that all of NCR will meet the April 1, 2020 deadline, the whole country may or may not follow suit. Then the question becomes: what happens to BS VI cars if they run on BS IV fuel?
Maruti and Kia say nothing. In fact, Kia says it has tested Seltos for a 100,000 km with BS IV fuel and didn’t see any signs of excessive wear and tear. Interestingly, Kia’s sister firm Hyundai says there will be some wear and tear but only over long periods. For instance, the particulate filter might get clogged or might require change faster if the car runs on BS IV fuel. But we are talking 8,000-10,000 km run here. And once again, this will apply largely to diesel cars.
However, unless both the car and the fuel are BS VI compliant, there will be no gains in emissions. But what about fuel efficiency or power? Well, that another story.

BS6: Why are small engines losing power?
15th Feb 2020 9:00 am
Multiple small-capacity motorcycles have been losing power with the shift to BS6. Here's why.
Author
Rishaad Mody
The past few months have seen a steady stream of BS6 two-wheeler launches/unveils, and almost every one of them has seen a small loss in power and torque. Why is this happening, and why didn’t we see anything as dramatic during the switch from BS3 to BS4? The reason is because BS6 demands a huge step up in terms of emissions control, so much so that nearly every manufacturer has had to switch from carburettors to the more finely controllable fuel-injection (FI) systems. But simply moving to FI isn’t the only cost factor, and another big price implication to consider is the extra precious metal required in the exhaust catalytic converter.
To make a rather broad generalisation, engines that produce more power require more catalyst material. When your motorcycle is a premium machine, raising the price by a few thousands doesn’t really hurt, and that’s why most of the performance-oriented machines from TVS, KTM and others seem to be retaining their power figures. But when you operate at the cutting edge of frugal engineering, every rupee counts, and so these manufacturers found themselves looking at a price-to-performance ratio that was extremely tricky to balance out.
Most seem to have concluded that the riding experience for customers is more important than the specifications on paper. And that riding experience lies largely in the shape and altitude of the engine’s torque curve. With the switch to BS6, everyone seems to be trying to smooth their engine’s power delivery and bring the torque curve lower down in the rev range to where the engines are operating more efficiently. Doing so results in more efficient combustion, which results in fewer emissions for the catalyst material to clean up – i.e. less catalyst material required! Stronger performance at lower RPMs will keep the target customers happy as well. Manufacturers like Honda have developed entirely new small-capacity engines to meet this objective.
Chatting with company officials reveals just how challenging this process was. For example, exhaust back pressure from all that catalyst material, and even the additional electrical load from addition of an FI system can have an effect, and this will be more noticeable on small engines.
Then there’s the fact that engines have traditionally been tuned to run very lean in India and this is one of the reasons why our fuel-efficiency numbers are so good. We could get away with this because India largely has the same topographic and weather conditions. However, lean burning causes more NOx emissions, so we now have to move closer to stoichiometric (or perfect) combustion where all the fuel is burnt. More fuel is burnt in this process, which will result in a small drop in fuel efficiency, but then again, that should be offset by the lowered torque curves.
It’s all quite fascinating and if you’re out there riding a new BS6 two-wheeler, it's nice to know just how much work has gone into making sure you have a cleaner form of transport.

I read this Article and the attitude of Maruti Suzuki is responsible for this.
Maruti Suzuki writes off Rs 125 crore on obsolete BS-IV parts

COVID-19 Lockdown: Maruti Suzuki Registers Rs 125 Crore Worth Of Unsold BS4 Cars As Company Loss

I would demand that higher Management team [Executive teams] salary be reduced for this fisaco. Shareholders please make sure you push this in AGM meetings.
Maruti is in business for decades. Do not they know what is the lead time is between the car dispatched from Assembly line till and car is registered!
Government was very clear during BS4 implementation that BS6 would be implemented on April 01, 2020. Maruti took this for granted!! So why Maruti failed to launch BS6 compliant engines on time and why in first place built up inventory of BS4.

A bench headed by Justice Arun Mishra said Bharat Stage-IV vehicles sold after March 31 this year and those whose details have not been uploaded on the e-Vahan portal of the government will not be registered.



The Supreme Court Wednesday recalled its March 27 order by which it had allowed sale of BS-IV vehicles for 10 days across India, except in Delhi-NCR, after lifting of COVID-19 induced lockdown, a directive which will impact registration of many of these vehicles.
Warning the automobile dealers of not taking advantage of the apex court by "playing fraud", a bench headed by Justice Arun Mishra observed that its earlier directives have been violated and BS-IV vehicles were sold during the lockdown in last week of March and after March 31 also.

"Do not take advantage of this court by playing fraud" the bench, also comprising Justices S A Nazeer and Indira Banerjee, said while hearing the matter through video-conferencing.
The bench said Bharat Stage (BS)-IV vehicles sold after March 31 this year and those whose details have not been uploaded on the e-Vahan portal of the government will not be registered.


The top court had on March 27 said it was permitting sale of 10 per cent of unsold BS-IV vehicles to make up for six days lost due to the nationwide lockdown which was imposed on March 25.
In October 2018, the court had said no BS-IV vehicle would be sold or registered in India from April 1, 2020.
During the hearing on Wednesday, the bench observed that sale of BS-IV vehicles had increased in the last week of March, when the nationwide lockdown was in force, and there were online transactions also.
Senior advocate Aparajita Singh, who is assisting the top court as an amicus curiae in the matter, said the court has recalled its March 27 order.
The bench observed that automobile dealers association have not followed its earlier order and have violated the court's directives.
It said that BS-IV vehicles were sold during the lockdown in last week of March and after March 31 also and now their registration was being sought despite the fact that order was passed way back in 2018.
The association's counsel referred to an earlier order and argued that court had said if BS-IV vehicle is sold before March 31, then registration would be done.
To this, the bench asked how dealers have sold these vehicles during the lockdown period in March.
It observed that details of more than 17,000 vehicles have not been uploaded on the government's e-Vahan portal.
The bench said it would ask the government to check the e-Vahan data and would allow registration of those BS-IV vehicles, whose details are uploaded on the portal till March 31.
It also asked the government to place before it the data of vehicles which were uploaded on the e-Vahan portal after 31 March.
The court asked the automobile dealers association to furnish details of vehicles sold by them to the government.
The bench has posted the matter for hearing on July 23.
As per an affidavit filed by an automobile dealers association in the top court, less than 10 per cent of unsold inventory of BS-IV vehicles was sold within 10 days of lifting of the lockdown.
It said that orders passed by the apex court in October 2018 and March 27 this year have been complied with and there "is no flouting" of the directives.
It also provides the data regarding uploading of data in the e-Vahan portal till March 31 this year.
In 2016, the Centre had also announced that India would skip the BS-V norms and adopt BS-VI by 2020.
BS emission norms are standards instituted by the government to regulate output of air pollutants from motor vehicles.
On June 15, the apex court had made it clear that no sale and registration of BS-IV vehicles would be permitted in the country and pulled up the automobile dealers association for violating its earlier order that had given some limited relaxation.
A livid top court had noted that as per the compliance affidavit filed regarding its March 27 order, more than 2,25,000 vehicles were waiting registration as on March 31 and this exceeded the figure which it had specified.
It had allowed registration of 1.05 lakh two-wheelers, 2,250 passenger cars and 2,000 commercial vehicles which were sold but not registered across the country.
It had said that registration of vehicles, which were to be sold out of the permitted 10 per cent, cannot be made without its permission and without giving particulars as ordered by the court in March.
In March this year, the apex court was informed about the unsold inventory of BS-IV vehicles -- around seven lakh two wheelers, 15,000 passenger cars and 12,000 commercial vehicles.

It was told that there were 1,05,000 two-wheelers, 2,250 passenger cars and 2,000 commercial vehicles, which were sold but not registered throughout the country.
The top court had then ordered that vehicles, which were sold but not registered, be registered by the authorities by April 30.
