Belgium: roll the tax-free oil !!

[professeur31]

It seems to me that you overlooked a few small details ... The people who operate engines with a high percentage of HV all (or almost, if not big risks ...) run in dual tanks, with preheating systems oil which bring its temperature to 75 ° -80 °, at which its viscosity is very little different from that of Diesel. The engine is supplied with HV only when this temperature is reached, which takes a few minutes, depending on the performance of the heaters.
If, as you say, "very high pressure injections (hp pump, injectors)"only take into account THAT viscosity, does this problem still exist? I would love to know ...

Yes, this problem still exists because the viscosity of the heated oil does not reach that of GO!
You should already know that for a common rail engine, even the temperature of the GO is important and that it is regulated to obtain an almost constant viscosity under all operating conditions.
When there are GO temperature management issues, the engine is already not working properly.
Do you see the problem?
Impossible to manage this correctly with the oil (at least with private means).

For this it would be necessary that the equipment supplier and the manufacturer agrees to take into account the fuel oil, manufactures the appropriate injection elements and reviews the laws of injection of its engine.

So why do some engines work so well? [...]

For the 2) I am talking about High pressures and not old generation engines that I consider to be forgotten because they are too polluting (they run on oil!).

And when you say "very good" it is only in appearance, for how long? and the pollution balance ...

I'm talking about new generation engines, Hdi and dCi in particular.
Well functioning only in appearance, maybe, I don't know ...
Generally, the "experimenters" are quite attentive to the operation of their engines, noting anything that seems suspicious, but I would be happy to agree that it is not enough and that the distance is not very great.
There are however "automotive professionals" on Oliomobile who do more extensive testing and disassemble their engines regularly to see what is going on.

Sorry, but I consider all this to be absolutely unscientific amateurism and without recognized validation protocol.

With regard to pollution, the forumOliomobile ers participated in a subscription to test the emissions of a Bora 1,9 TDI, with diesel, then 100% HV. The results both met Euro 3 standards. It is certainly not a "latest generation Common Rail" engine, but I do not think we can speak of an "old generation engine that is too polluting". .

So sorry!
Euro3 is exceeded from home exceeded!
We are Euro4 and Euro 5 is in preparation.
For forumeurs, I told you what I think above.
Again this is only my opinion and you can think otherwise, it is allowed!

The solution, then, would it be the old generation diesel powered by oil and decontaminated by water doping?

Uh, well it depends on which solution you are talking about!
I understand: easy adaptation, honorable perfs, reduced installation cost, low pollution, low consumption.

If this is the set you are looking for, I answer yes !!

OK thanks for these notes.
For viscosity, I have to find the curves, but we must not be very far ... but if you say that this is enough to make the difference, I would like to believe you.
It is true that explained like that is immediately clearer. (you see you can ... )

So in fact, this problem of viscosity would almost alone explain the "chilliness" of the manufacturers and the push towards the Diester which does not pose the same problems, if I follow you?

[...] Sorry but I consider all this as absolutely unscientific amateurism and without recognized validation protocol.

Not scientific, it seems clear to me, but amateurism is not completely true since some professional diesel engines also test ...

Can you tell me what you work in?

Exceeded ... mwouais ... until January 2006, Euro3 was still in force, right?
And Euro 5, is it for 2009 or 2010 if I'm not mistaken?

For forumors of Oliomobile, you think what you want (amateurism, etc ...) but the measurements carried out are all that is scientific ...

Good night.

Exactly! In any case, this is what they claim.

Uh yes, I'm a motor technician and I'm working in education right now.

Yes exact but we must look to the future.

And Euro 5, is it for 2009 or 2010 if I'm not mistaken?

In theory it was 2008 but hey ...

For forumors of Oliomobile, you think what you want (amateurism, etc ...) but the measurements carried out are all that is scientific ...

Perhaps, but I think that they do not have enough means at their level.
You see, it's not to criticize them badly (quite the contrary) but I think it would take them 1 year to obtain the results that a manufacturer would have in 1 week (whether in tests or improvements).
Believe me, only manufacturers are able to develop engines passing Euro 4 or 5 standards in oil carburation with the same reliability as GO carburation.
The only positive thing that I see in their approach, moreover quite respectable, it is precisely to attract the attention of the manufacturers to make appear the benefits of the oil (of which I am convinced but not in n ' no matter what condition).
Do you understand where I'm coming from?

So my last word will be:
MISTRUST.

... or rather caution!

[vttdechaine]

To say that Euro3 is out of date, I don't know.
We should especially compare the constraints of this regulation with the new one (Euro4).
If the gain is 2%, I do not believe that we can qualify the Euro3 to exceed.
As such, a car which would pass Euro3, could with a little development, pass Euro4.

My bike passes Euro 25!

And still 17,5 km today (28 yesterday) to go to work in town outside my agency

62 km in one week of work in HPV and VP Thermal.

What about HBV? In MIAM salads!

[Woodcutter]

8) My bike passes Euro 25! [...]

No, no, no! Because it is made by Chinese subcontractors for the Taiwanese, that you put petroleum grease on your chain and in your ball bearings and that your tires are not in natural rubber!

Well, I'm beaten, I would only have 17 km of mountain biking this evening (but with a "leisure" part )

[gegyx]

And how many hot showers after your sweating?
