Yes I have seen this video.
Produced by a DOW member Sergei “Serg” Legunov. He in Ukrainian with his own youtube channel GenGaz.
He started this topic and others here on the DOW:
He asked us for reference help. Then later did produce and release that video.
Read that short topic thru to post #8 where he from his 600+ articles and books read has developed very interesting ideas on diesel engines woodgas converting. Well worth considiering.
Yes in this video the Mecedes is for sure his converted car. Like DonM saw the black wood chunks look to be heavily torrifed wood chunks. Note no dust pouring them in. Not charcoal.
The system (one of 2-5 he says low tar ones, he now knows of) I do not know the origins of this drawing. But do note that the 1st heat exchanger/dropping chamber would have probably forced air in and that then very highly heat boosted air goes into the gasifiers double row of air nozzles. Like a W.K does. That hearth tube very heavily insulated looking with internal refractory bricks? The second illustrated heat exchanger would have to have a forced air flow. And that indicated 70C outlet air from it then used for wood conditioning.
And he talks about nearly clear condensates. That talk plus the black block chunks sizing says this is not an actual charcoal gasifier.
But the blacked wooden fuel blocks, not raw brown wood and lack of hopper monorator features says not a raw wood gasifier either.
Him and other Ukrainians, and Russians I’ve talked to . . . along with some in South America, Africa, S.E. Asia are developing under different restrictions from us in the U.S./Cananda, even Western Europe.
So in my opinion he is not actually cheating using a pre-modified improved input fuel-wood. After all that is what charcoal is.
