in 1986 you could only show this to your friends and colleagues. now 1000s of people can see.

Sir, may I offer my congratulations. You know, such masterpieces should never be in the dark hidden away for may years, but they should occupy an exhibition case in the most prominent position in a home, as this is something to be proud of.

Should be displayed in the Smithsonian!!!!

Your adjustable compression mechanism is fantastic! Scratch that, the entire engine is brilliant! It started so easily! I'm amazed the engine ran so smoothly while adjusting; that was a rather extreme change in compression ratio. Thank you for uploading this demonstration!

No idea how this was recommended to me 5years later………what does changing the compression ratio do ?

@@magnustveten492 Thank you for reminding me to watch this again. Changing the compression can be done for several reasons, including increasing/reducing output of an engine to optimize it for power or economy depending on the application, or to account for atmospheric changes. In this case, the method of adjustment would also change the harmonics and powerband of the engine, allowing it to generate peak power at different speeds instead of one static point. But the neatest part of this system (just my opinion) is the fact that because it's a 2-stroke, wherein the pistons act as valves and cover/uncover the intake and exhaust ports as they travel, this system is also effectively an infinitely adjustable variable valve timing (VVT) system. This little engine blew my mind.

@@AtlasJotun thanks for that explanation :) what you say make sense and makes me appreciate the engine more :)

What an incredible engine! Thank you for sharing this amazing engine.

Wonderful, both in terms of engineering, and aesthetics! And also the video is very well produced. Thank you for sharing this. It is a pleasure to see people do great things just for the joy of it!

You are one very clever man. I am a big fan of the opposed piston engine. Your design is simple yet very sophisticated.

This man is beyond ingenious!!!!!! Great machinist too , incredible attention to detail !!!!!! This man might be the guy who trains geniuses and craftsmen!!!!

Wow! What a craftsman! Best of luck! Thanks for the video.

I take my hat off to you Sir for having the brains and ability to build such a beautiful engine, John from sunny Devon UK

Whoa, that is a crazy little engine - I'm very impressed! I love the stuff you make. :)

I hope that all of your amazing thought and intricate work is preserved for generations to come. Not just digitally. Your work is incredible. Thank you for sharing your craftsmanship and knowledge.

These engines should be in a proper museum! Wonderful exhibitions of mechanical engineering.

G’day and greetings from Tasmania Australia 🇦🇺 you have done a truly beautiful engine the machine is terrific. Thank you for showing it and explaining how it works. Regards John Kinnane

Another wonderful piece of work. Your engines are all great works of art, I just love them! I wish I could afford one.

You, Sir, are the Tesla of the engine world!

this is one the most beautiful engines i ve ever seen.

This is so beautiful, you are a genius, well done

Find Hansen, great engineering ! A genius and a first class craftsman. Thank you for sharing !

Wow! The incredible amount of craftsmanship and engineering of this engine is astounding

Hi Find, what a wonderful engine. I have searched the internet trying to find some drawings which would be similar to yours, it has been a hopeless task. Your knowledge and experience as an engineer is absolutely outstanding. These quality engines of yours are priceless. I just wish there was some way that this knowledge could be passed onto future generations. I have found all of your engines to be unique, this one is no exception. I would gladly purchase plans if I could. Thank you most kindly for sharing this lovely moment with us. Kind regards from England UK

Bravo! Changing the stroke! Opposite flywheels! Excellent proof of theory. Thank you for sharing.

amazingly complicated design my friend :) very interesting

its not really complicated at all... the fly wheels at 2x crank speed double as counter balance shafts... variable comp concept is seriously flawed though in a spark ignition engine though... thats exactly what a throttle does... the effect of controlling port timing is a major step up... diesel's a totally different c/r principle though

Very interesting, I have never seen an engine like this before. Your construction skill is most impressive. Thankyou for sharing !

you are a genius man

You're always made impossible things possible, Find, thank you so much for posting such great engines. Your another rotary radial two-stroke is the most exciting for me, because I can't imagine how fuel is sucked in and how it missfire less then even most 4-stroke model engines

Truly clever design. Excellent fabrication. Great proof of concept. I expect long term lubrication is the only thing limiting practical use.

Unbelievable craftsmanship. Truly a work of art.

Mr. Hansen, you make me proud of my home country 🇩🇰

This is not a engine, but it's a clock. Complimenti. Andrea

Beautiful work here - my respect to you sir.

You are a very clever and interesting man. Thanks for uploading the engines you have built.

I'm planning on building a dirt bike with an adjustable-compression opposed-piston engine. The fact that you built this in 1987 makes me hopeful it will be possible to build an efficient & compact version with today's parts and technology. Thank you for posting!

That is truly a work of art. I am a machinist and since I have gotten started in the trade I have wanted to make something as nice as this. good job.

A great piece of kit, Put in a prominent place to display it , I feel confident that guests to your house would get a real buzz out of seeing it run.. I would , You'd have to frisk me when I left to make sure I hadn't popped it into my manbag lol

You are a genius Sir............so much detail !, thank you

Must have been fun to build. Very nice work !

Very neat Mr. Hansen. I like the system to change compression and also the counter rotating flywheels... Thanks for posting!

Outstanding engineering and knowledge combined. Thank you once again.

You are a GENIUS !!

Brilliant engineer

Beautiful piece of machinery, very well done.

Magnificent piece of work! I make one of a kind stationary steam engines and yours dwarf anything I have made. Thank you for sharing your work. Fred USA

Very clever design, looks really cool too. Mad props!

this is an example of a wonderful piece of kit. thanks for showing it :->

An amazing designed opposed piston engine!⚙️👍

Engineering genius.

Genius. Mechanical variable compression.

Cool to see such a different kind of engine.

That is very clever, I have not seen one with adjustable crankshafts before.

Very interesting engine, Find. Lot's of innovative features.

Nice ! A true craftsman and a genius !!!

WONDERFUL ! Very interesting - thank you !

Absolutely fantastic. What a wonderful piece of engineering. Being a machinist I would love to have the plans to make my own. Excellent Hr. Find.

Wow, that is incredible. Thanks for sharing!

Very impressive , you are very clever mr 👍😃

Awesome, wish I had the tools to make one , love your videos!!

Beautiful. Would make an amazing motorcycle engine.

Fantastic! Excellent work!

u built the thing and it works that's prity smart that thing looks roadworior steem punk and its art:)

Wonderful machine work and design. You need to make Model Trains and custom hunting rifles, 2 of my favorite things.

Very impressive 👍

Sehr schöne Arbeit, super und sehr interessant

Can you make a video about yourself and how you build this stuff?

This is a good experimental setup, I'm sure it could be used to demonstrate the relation of fuel properties, timing and compression ratio.

Das ist Klasse ! Ein Meisterwerk !!! 😀👍👏

Stunning.

your the man! sweet engines

Fascinating!

I was silent till the other flywheel was adjusted. Cool

4:39.. my favorite part...

xlent work! and timely as there is much renewed r&d happening now with o p engines for consumer use.

Beautiful

You sir, are a BAD ASS!! Amazing intricate detailed work. What was or is your line of work? I love watchin these videos. The three cylinder rotating engine, with one coil that excited the plugs as the went by, so fuckin cool!!! Great job dude!!

you are genius !

nice sir I like engines

Amazing motors! Really pieces of Art! What tools and machines do you use to build these wonderful engines?

This is quite wonderful. Beautiful design.

Truly, an amazing creation. Are your engines based on historical sources, or are completely your original designs? I suppose, like all machines, a little bit of both. Whatever they are, they’re absolutely fabulous. Thank you.

wow. !!!!

Awesome :)

Tillykke

Only from Europe..Wunderbahr !

Genius. I wonder if it is natural aspiration or forced induction.

Fantastic skills you have! By any chance you are selling a motor?

Please build the first running dckers double cycle engine to see on youtube....new ic engine deckers double cycle.....

Is that the flyback from an old TV? There's no reason why that wouldn't make an acceptable coil for the ignition... I do really like the way you put your thinking into this one, not just as second thought.

Voice crafty work

Hello sir this is just an amazing project to evil do you sell any of these projects? There's something to be saved and I just find this amazing. I know how to build stuff but not at this level. I would love to be able to look at it and run it and enjoy it and share it. Thank you my name is Bob Ordewald and I'm in Virginia USA

genius

How is this engine lubricated? Oil in the fuel?

can you get a video of it revving?

Can the compression be adjusted high enough to run without spark?

Hej Find. Dine motorer er virkelig flotte! Er det muligt at man kan komme og se dem? Mvh Christian

hej find hvad har du af baggrund, det er nogle imponerende maskiner du får bygget :D

Thats amazing! My only question is why would you want to adjust it so that one piston almost doesn't move? That pretty much defeats the purpose of it being an OP engine

@klausbrinck2137

Just for experimenting of what the best result would be. It is a unit good for research, but in real-life, compression shouldn´t be adjustable, since, through experimenting with this model, the optimal compression should have been ascertained.

Any plans available for this engine?

FRON BRASIL OK MACHINE.

I wish i ciuld hang out with you for a while so you could teach me you have lits of knoldge i would love to learn

Can you put it on a dino meter and check the output horsepower in the torque output and see what you got
