I have never seen a working example but the single cylinder ( 600 cubic inch ) 2 stroke semi diesels that Lanz made were supposed to be easily adapted to woodgas. ( just bolt it on the front )
So there if its all about the least number of parts find an old bulldog or Ursa…

Good Morning Mr Tone,
Having now again little girls in our lives has taught me a way to explain-with-pain the comparison of IC piston engines with all form of external combustion engines.
The children’s play ground merry-go-round!
These have six to eight segments. The steel bars between segments are your make go-around power input points.
To get it going all loaded up with many kids mass is quite the effort.
Either stand firmly on spot and golfers torso, twist hard pull through swing it from segment bar to segment bar.
Or grab on and run it around up to speed.
Once up to speed, really really hard to keep up that running around it! ( piston steam cycles limitations)
Instead: then Stand in one spot. Grad and twist the segments putting in a shorter duration, rapid intense pulses of energy flinging.
Faster and faster, the kids say.
Then just grab onto every other; or even every third segment bar (no time to torso twist anymore) using just arms-shoulders power input pulses. Easy then. Once you get your hand-eye; grab, and fling timing down.
IC piston engines with crankshafts we are just grabbing power in short segment angles of rotation.
The more cylinders the more overlapping power segments. The faster the running RPM the the more power segments to work with. Carry over smoothing between these power input pulses.
External piston combustion is a constant pressure/exhaust/reset/repeat. Great for starting torque. Falls down on cycling range. Nearly constant temps then. So virtually all power must come from only delivered pressure-volume.
Turbines; gas or steam . . . .choice must be made for starting torque or RPM power delivery. Or complex variable types trying to do both.
The real down falls of external combustion being the heat losses with remote systems delivery’s.
Or the all HOT, all of the time expensive materials demands; of the contact combustion types.
Anyhow. Anyone. Go do some merry-go-around make kids happy powering. And think what is happening. Try yourself different techniques.
You will see. Ha! Ha! Sore muscles and joints will tell their story!

I thought about those merry go rounds for powering an air compressor. Decided that if you put some kind of air foils or paddles at the perimeter that the wind that was powering one side would also be pushing against the other side negating the thrust. I guess there is a way to position the foils to alleviate that but that kind of engineering is way above my pay grade, Still a set up like that would produce a lot of torque which is what air compressors thrive on.
Tom,
At first I thought you were thinking of utilizing child labor. Ha! They need something worthwhile to do to prepare them for adulthood.
Yup I am with marcus on that one. My newest vehicle is my 2003 Dodge Ram. And guess what not able to gasifiy it. Bummer. The older vihicles are the easier to gasifiy this is the simple truth. The OBD 1 and early 2’s. are best in mpfi engines. Heck a brand new car forget it. Well a 100% EV with a gasifier/genset on the back maybe. Would that look funny or what a Tesla going down the road and no need to stop at a fast charging station. Lol. Someone should show Leon Musk.
Now that some of the DOW members are showing us that diesel engines can be gasified, this is a game changer for wood/charcoal gasification. Diesel engines getting 75 to 100 miles on a gallon of diesel? That would be Nice. And it could be your own bio diesel that you are making. That is really super nice game changer. Right?
Still I think it will have to be the older diesels not the new ones that they are making these days.

Diesels last longer by 100,000 miles, less profit to produce fuel. Gov. made emissions laws more restrictive to favor the gasoline engine. Oh and we wanted high perfomance fast cars too. Diesel you lose on that one.
A quite ride forget it. But I like the sound of my gasoline engine and tail pipes. Lots of factors ones we do not even know about too.
Now it is the silent ride of a EV’s, no noise polution.
Oh brother what next. What comes around goes around again and again just in a new wrappings and box for people to buy. H yes it is about making monies and big profits too. As they say nothing new under the sun. May be but I am not holding my breath until it comes.
Bob
I think gasoline stinks too. But diesel is safer to handle. Yes in the pass 20 years they have made a lot of improvements with diesel engines. But the older ones are better from what I am seeing and are easier to convert over to wood gas. Not the new style diesel’s that they making now, if so I would like to see one run on wood gas. Seeing is prove and facts that it can be done.
From the mid 90’s they the car manufactures have made it more difficult to make a vehicle to run on wood gas. Was this on purpose? Do you think they even know about making wood gas? Ofcourse they do and the oil companies and auto makers and governments all know about it and are all in the same bed together.
It was a good thing they didn’t realize it in the late 80’s and early 90’s with the OBD1 and early OBD2 systems and the MPFI engines. Oops, their mistake on that one. But they tried to corrected it. With the later OBD2 systems.
But not if you know how to work around the OBD2 mapps. It is over my head for now until I get more knowledge on the tools and work around prosses.
