The company becomes the first 3W single-cylinder diesel engine maker in the country to secure BS-VI certification. This is a significant step to support three-wheeler makers in India.

Absolutely horrifying news for the environment conscious person in me.

I was gleefully waiting for these overloaded, abused, black smoke belching single cylinder diesels to be taken away from our roads.

Absolutely horrifying news for the SAFETY conscious person in me. I have seen first hand how these deathly contraptions can turn turtle, not to mention the errant ignorant drivers pointing out their mere one inch fingers to indicate a turn!

:Frustrati

Any details about this engine? 3 Wheeler - Philosophy underlying it is very low cost. A low cost engine is very unlikely to meet automotive BS6 norms. So how have they done it? (Am assuming that the norms for automobiles and 3 wheelers are identical).

On a positive note, I think it's good that the three wheelers will also be BS6 compliant as other vehicles, so hopefully they will help reduce the emissions whatever little bit they can.

With the introduction of the Bajaj Qute which I'm starting to spot more and more often nowadays (and I hope similar 4-wheeled competing products follow, in the quadricycle segment), I wish they'd enact a law to completely obsolete 3-wheeled rickshaws atleast for human transport.

And maybe give incentives to present owners to upgrade to the likes of Qute.

If it meets the norms, that is good, right? In India, there is a good use case for such vehicles

if meeting the norms is the only target, then even our national diesel engine can be made to. It's a question of real world operating conditions.

They are seldom utilized to haul it's stipulated load; overloading and (a different kind of) pedal to the metal driving. Or fix floor boards in every angle possible to make 'seat' for additional passengers; not to mention the near perfect suicide mission driving which fails only because road users rush in all directions to give passage.

The points you mention above are something very different which have to be addressed separately. All I'm saying is that these vehicles have lot of use cases in our country and it would be good to have them meet the emission norms. I personally have used them to lot to transport personal effects that, for eg, do not fit into my car.
Agree that they are misused many a time beyond their capacity, overspeeding etc, but these are to be handled separately and not necessarily restricted to 3 wheelers like these.
One raw apple does not mean you throw the full basket out

It’s a good product. At the right time. Do they provide technical details of how they achieved it? As I understand BS6 diesel has less sulphur and therefore is less able to lubricate the injectors.

I read that 80,000 people die due to coal powered plants specifically.
Here is that link:https://www.theguardian.com/world/20...ons-greenpeace

Is there anything like bs6 coal?

The solution should ideally come from our Oil Marketing Companies (OMCs). Euro 6 grade diesel elsewhere in the world comes with synthetic lubricity additives which supplement the erstwhile Sulfur content and keep up the slippery nature of diesel. One assumes that India's OMCs will do the same. If not, we're looking at armageddon. India's logistics should grind to a halt if BS 4 and older diesel engine injectors fail when run on BS 6 diesel.

It’s worse than that. The article below says that this diesel has double the water content compared to regular diesel.
At low temperature the water is expelled.
It means that you cannot leave your car unused for a long time. It is likely that the bacteria grows in it.

How will an insurance surveyor know if an injector or engine is damaged due to wrong fuel?

You need him to be qualified as a bio chemist and petroleum expert.

What about agricultural pump sets?

It means that fuel stations will have to have another pump for this new bs6 diesel. Since Maruti has already announced that they won’t make bs4 diesel cars from 2020 who will benefit from all this?

Not used anymore, solar powered pumps replacing/replaced them.

As for tractors, we plan to use it with 2T oil mix, since they all are just DI.

Funny you should mention this; I vaguely recall seeing news reports of bacterial slime formation in the fuel tank of newly purchased BS 6 diesel cars...Sulfur is anti-bacterial too (why it is an ingredient in skin ointments). So while lubricity additives can keep diesel slippery enough, slime formation seems to be in the offing for diesel vehicles going forward!
But why would an insurance surveyor even be in this grim picture. If it is vehicle maintenance pains we're talking about, insurance coverage doesn't apply here.
Ideally, all fuel bunks are supposed to totally switch over to BS 6 fuel countrywide. But I've heard rumblings that our OMCs cannot roll out BS 6 fuel countrywide, come June 2020.

I was thinking if there is a warranty claim on an engine that got damaged using the wrong grade of fuel, such a claim may be tricky.
I agree it’s not very likely.
