It's a shame ... You could have advanced the knowledge here, but given your answers, I even wonder if I have to believe at the beginning of what you said ...


But you believe what you want my friend!

Sorry to have touched your susceptibility, but that's the risk when playing divas, style: "I know, but I do not want to waste time to inquire" ...


If you reflected a little, you would understand that if I did not want to waste time informing people, I would never have intervened on the forum.
What I refuse is closed people like you who say white when the other says black!
If not reassure you, I do not have the infused science and what I learned, I know it therefore I can make others benefit from it; provided, however, that they do not say anything by way of answers or comments.

Regarding to learn to speak to people differently [/ i], I return your advice to you: go and reread your big answer in bold on the operation of the engines and come back to tell me that it was friendly, friendly and everything ... and everything ...



Yes and well I persist and sign!


PS: where's that an insult?


pffffffffff [

Here ? Interesting as appreciations ... Any examples please?
It is all well and good to speak in a vacuum when you start to be vindictive with others, but at some point you have to justify yourself by something other than general remarks and "pfffff" ...

The only thing I did was to question you to deepen the subject of fuel oil, I don't see what makes you angry :?: :|

Again, what interests me is the technique.

Hello
Focus on oil!
it looks like walking in a corridor full of petroleum jelly
it’s oil that’s the point. forum feels like attending an ice hockey battle.
Slap the pulley a little ...

Likewise!
If you want, tell me what you want to hear about fuel oil (that it has no drawbacks in an engine for example) and I will tell you.
Like this everything will be fine! : Cheesy:

For the 1) Viscosity
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 ...

There you still have questions that call for answers that are obvious to me?

Otherwise bye bye.

Well...
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 ...

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.

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". .

And then, of course, I'm the one who's going to be blamed because "i have to learn to talk to people"... : roll:
This is the typical example of what I consider to be a behavior of diva !
If you think about it a little, you will see that all my questions, my curiosity about technology, were well founded and that therefore, before sending me out for a ride like the last moron, from the top of your supposed technical superiority, you might have be able to ask you some questions.

When we lecture with the morgue you show, we try to be on top if we want to avoid flashbacks ... : Mrgreen:

That said, thank you for having given me a few minutes of your time, which I have no doubt for a moment, must be very precious. : Wink:

For the diester, no problem for the operation of an HDI up to 50% max.
A small modification of the HP pump is nevertheless necessary.


The old generation PSA diesels (1.5D AX, Saxo and 106 for example) were designed to work with 30% diester without modification.
This proportion has increased over the years from what you write.

In addition, I read some of your posts, you seem to put all the "latest generation" injections in the same basket but nevertheless, all of these supply systems are very different from one manufacturer to another . Can we therefore generalize the modifications or should they be made on a case-by-case basis?

I actually think that we should not generalize and that the modifications should be based on the type of engine and especially the type of injection (common rail, pump injector).
Now, it is certain that to do something good (reliability, consumption, pollution), all (or almost) the cartography of the computers must be redone as well as the adaptation of the injection elements (HP pumps, injectors etc.) .).
I really think that this work can only be carried out by the manufacturer by producing an engine / injection equipment / mapping unit adapted to the fuel oil.
The other initiatives will remain in my opinion marginal and of the order of DIY (even if very well done).

For the proportion, it is correct, it tends to increase and according to the results of tests and tests in longevity, certain manufacturers agree to recognize the normal functioning of their engines with nearly 50% of diester.
However 50% of diester is really the limit of the tolerable!

Well, I hope I have answered your questions.
I specify that I am not a detractor of fuel oil but that I try to put things in their place by being as objective as possible, whatever the network of installer which multiplies (business requires!) .
So my last word will be:
MISTRUST.
