And where is the problem with the oil?

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 ...

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

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.
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". .

Otherwise bye bye.
And then, of course, I'm the one who's going to be blamed because "
i have to learn to talk to people"...
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 ...
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.
