It is not suitable on these engines.

But it was on previous, and then people run Heaters, 2nd tanks etc.

 

But Taxes / Excises & Duties are the incomes the Governments want.

 

The eleven million engines are getting as little alterations as VW get away when Governments allow the 'fixes',

and that is highly unlikely to involve 'modifying' to use Veg Oil.

(There is enough issues with the percentage of Bio they are able to run.)

Why just "today's"?

 

OK, award won outright for a succession of posts, all of which hint at conspiracy theories.  Congratulations!

^^^^ Your count is growing as you post about my post. LOL

Referring back to a question I asked in another thread before the VW scandal broke would running Veg oil instead of diesel prevent the emitting of harmful particles including NOX? As veg oil is not a mineral oil derivative surely the particles generated in the smoke are less harmful and not carcinogenic. Could Veg oil be the solution?

 

But my Greenline has a sticker inside the fuel filler cap specifically saying Bio Diesel MUST NOT be used.  Just how much modification would be needed?

.

 

Great!! He's gone quiet!  Was it something I said?

So if I've got it right, VAG have caused worldwide starvation as well as the death of countless squirrels in the trees above our roads?

Still loving the diesel Yeti.....

No place does anyone say VW caused the worlds starvation problems.

 

But growing crops to fuel cars and burn to produce electricity while people around the world have not enough to eat is a scandal.

But then some are more interested in funnies.

Weld done you have managed to turn my technical question into a pointless geopolitical morality issue. If you can't answer my technical question then please let someone else who can before you run the thread off on a tangent. Just a simple yes or no will do.

 

Again for someone with the knowledge: can the E189 with a few simple mods be made to run on veg oil and would the exhaust contain NOX / pass the text?

 

if NO (I know the previous engines in the MK1 can run it ok), is it the common rail system that stops veg oil being used on the MK2?

No it is not easy, practical or Economic to have the Engines running Veg Oil.    For the Technical Reasons of the System as designed.

If it's in warranty, I doubt if any German engineer would approve it.

If it's not.......it's yours obviously and I sure there is a technical section that could give useful advise.

The old PD engines probably would but the higher rail pressure ones are extremely unforgiving.

I think peak combustion temps would be very similar with biofuel. No reason to suspect lower NOx AFAIK.

Again for the avoidance of doubt  = 'Easy, practical and economic' were not factors in my question and are not expressly technical in nature.

What Im asking is with regards to the viscosity of the liquid potentially killing the fuel pump and injectors due to the higher pressure run in

common rails. I was asking if a modification is possible to allow this to work your reasons for it not working are not technical but cost based.

You also haven't answered if the exhaust contains NOX which is the crux of the question.

Scholarly articles for veg fuel Nox.

& its all there.

No, give up!  Must be a different language in Tayside.

Found an article that said cooking oil produced less NOx but Biodiesel produced slightly more so that answers the question. Even though its less I suspect its enough to fail the test in California so not really worth perusing regardless of if a Common rail can be made to run on it.

VAG, and nearly all other manufacturers, do not recommend or approve the use of more than 10% veg oil in the modern, high pressure pumped engines.

Well VW and Hitler had this thing going on, So I blame Hitler for all this mess.

No.

The pumps are too high pressure and the fuel cannot cope with that.

Bio fuel does not contain sufficient lubricants so pumps fail quickly.

Injectors wear out more quickly, as above.

Bio is also generally more acidic. so can cause problems with hoses and seals.

Unfortunately, the 'ingredients' that form NOx gases are nitrogen and oxygen; rather abundant in our atmosphere. The key to avoiding their generation is lower peak temperatures in the combustion chambers, regardless of fuel type.

Or less oxygen in there.

Godwin's Law invoked for the third time.

Can we blame him as well? Actually that's only 1 Hitler reference to every 700 posts or so. Not a bad average.

 

The rate these emissions revelations are coming, there wont be a VW to blame soon.

Goneoffskion1, for reference the above is a technical Answer.

isn't Godwins law something to do with the Hitler mention, ending threads too?

Bio.  

and Straight Vegetable Oil (SVO) and Used Vegetable oil (Waste Vegetable Oil - WVO) are very different things.

 

When we produced VWO for our own vehicles we then added the Drain Cleaner & other spirits we wanted to produce

the Bio Fuel', which we ran in the simpler (EDIT) engines,  TDI 200 Land Rover engines and the likes.

Up to 2,500 litres a year for Personal Use.
