Beautiful engine, running so smoothly. thank you for sharing.

What a beauty. What a sound. This is by far the best model engine i have ever seen. Thank you!

Excellent! I love the roller bearings, push rods, and flywheel. That flywheel is straight too..I hate seeing janky wobbly flywheels. Beautiful engine!

Nice to hear that someone else likes Jan Hammer's music! Great engine, an absolute beaut

This is truly amazing how someone builds this thing from an idea. amazing work

Outstanding, now I need to find out how they work. Thank you for sharing what must be hundreds and hundreds of hour work to terminate in such a beautiful engine.

That is I'm sure the most beautiful engine I have ever seen! I love the sound and I know I could watch that for hours! Amazing work! 👏👏👏👏👏

Seeing the valves popping @5:10 reminded me of the U-96's diesel engines in Das Boot when the mechanics were flaming off excessive gas and the petty officer passed through and said, "That's a good way to waste fuel!"

your channel is hugely underrated. all of your engines are so elaborate and well-built

Very smooth and quiet. Geweldig.

Pure artwork. You are a true craftsman sir.

Thats a mechanical masterpiece, Ed. Well done !

This is beautiful, well done.

I actually does resemble a inline 4 engine. I'm really glad a video like this exists.

Excellent work must have taken a long time to build I have worked on marine engines it take me back an can appreciate the work that's gone in to it

Wonder what a radial would sound like? Fantastic work!

Wow, top engine, thump up

Very nice machine! A real 'vakman' :-)

Fantastic bit of engineering

Sehr schöne Maschine. Man könnte über den Flammen noch ein Rohr anbringen und in diesem dann gleichzeitig noch Kaffeewasser oder Teewasser heiß machen . Quasi eine richtig "moderne" Kaffeemaschine. Dann an Sonntagen so ne richtige Zeremonie gestalten . Klasse gebaut jedenfalls. 👍

Pure genius!!

You are amazing! Incredible work. Thank you for sharing.

It is a real masterpiece. Bravo

Some engines have a hood over the flame inlet so the flame doesn't come in contact with the engine parts above it, might reduce the carbon buildup. I wonder if there is a way of adjusting the amount of the flame in time with the inlet opening so as it opens the flame gets bigger, and when it closes the flame reduces. I know these vacuum engines were very inefficient in their day. Lovely work.

Sehr schöner Klang!

A STUNNING CREATION

The sound in slow motion is really nice.

Very nice build. I love it. I wonder if it could power some kind of device. That would look great on a bicycle even if only for assistance

that is a great little engine man. mad skills.

great work

Awesome work! :)

I like the sound of this one... what event timings are you using for the valves, and what bore/stroke are you using?

A beautiful piece of model engineering. I wonder if you have measured the power? I can't imagine a vacuum engine of a simular size developing more power than this one.

Excellent work! I apologize ahead I'f I'm mistaken, but It looks like you've made the cooling heat sinks on the cylinders out of Aluminum, press fit to a brass cylinder. Aluminum and Brass don't get along. they eat at each other through a process called Galvanic Corrosion. Again If I'm wrong, I apologize. I just hate to see a lot of work go bad due to mismatched materials.

I would love to see this engine in a vehicle!

nice video bro and good Invention

Very impressive, congratulations. :)

Just came across your channel and subscribed. Very nice work

Very nice machine! But in my opinion too complicated :)

Nagyszerű munka!

This would make a good preppers generator, no carbs, fuel injection, or electronics. What's do you think the power output might be?

Ein kleines Meisterwerk und sehr Gut umgesetzt !

Fantastisch!! Sehr cool!

What if to conserve fuel and avoid open flames a header was used to direct hot air into each chamber and use a single fire source? beautiful build by the way and a work of art so in this case open flames are cool...

Mechanical engineer extraordinaire ... dear Lord ..do you have any engines you could part with

Would love to see it's mass production..

grest job!

could you control the engine's speed by varying the temperature of the cylinder walls too? aka higher temp difference? what sorts of problems would that cause? perhaps a liquid cooled version?

Wow really nice I wish I had the equipment to make this it’s really nice though you did great

Cool engine.

Smooooooooooooooooooooth A+

Wow! How? 😮😮😮

que belleza y que terminacion de la piezas

КРУТО.

Could this run indefinitely -- so long as the flame or the heater is nearing to that inlet/outlet?

SUPER.

Why do these kind of engines need to warm up? I thought the cooler the cylinder is, the better, since it takes its energy from the temperature difference between the flame and the cylinder wall.

could have another engine (stirling engine) sopping up the excess heat from the unused flame.

Excellent

Is it possible to build a larger version of this type of engineer? I mean that would possibly weigh up to 200 pounds and above if possible.

Out of curiosity, what is the average thermal efficiency of this engine type?

Should make one with enclosed flame travel chanber

تحفة ميكانيكية

Do you have to Oil The Engine before each run?

How much does it take gas or whatever in hour/Liters. Looks good idea to me!

Why do you need to warm it up? Won't a cold cylinder mean a higher temp difference?

Can these produce enough usable energy to drive an automatic transmission?

Yout can build one FOR me?

How many weeks for programming the cnc?

Why dose the engine require a warm up time before starting?

Would you ever consider selling one in kit form?

What's the output power of this engine?

wow

What is the max RPM of this engine?

I'm curious, any idea how much horse power it produces?

Very similar to engine u-boot.

I want one

What is it's torque

So how much power does it make can you do anything with it make electricity or run a sewing machine or something

It's look like sewing machine.

how much horse power do you think it has

Why don't you try a engine that can use easily and filter h2O from sea water. Vaccume + sea water = release -H2O and -Energy

Inspiriert vom Lutz von Bengs?

Plans for sale?

Nice gta vice city theme song

4:45 The impulse is regulated by the number of gears left in the starter wheel, in this case, about 1/3 of a turn. A mechanical regulator, I hope to learn its proper name. It is very beautiful, like everything else in this machine. Thank you so much!

great add a egr system on that you wont need fuel at all any more that is one of the fuel cells secrets with adition with plazma ignition and waste spark ignition system

Lol confessional

какая мощность?,кпд?

bio ethanol

What I do NOT understand is why they engineered these engines upside-down! Consider this: if the flame inlet were directly in the center of the top of the cylinder head with the flame directly above that inlet, and then you TURNED THE ENTIRE ENGINE MECHANISM UPSIDE-DOWN, then those four flames wouldn't have to be blazing away wasting 90% of their energy into the atmosphere; they could instead be tiny little flames efficiently entering those inlets, couldn't they? Why do I have to do all the thinking around here?! :)

Very well done shows vast mechanical skills which I do not have. If you get done playing with it and would like to sell it I may be interested thank you for reading my post
