I had my runaway situations, when the engine failed to start after several start attempts caused by missing compression, it could be a sticking exhaust valve. Then after full compression again, the engine started with very heavy pre-ignitions because of the unburned fuel in the combustion chamber that ignited far to earley, and ran on that fuel for a few seconds with very high speed. That is why I made a safety valve, mostly to prevent the heavy pre-ignitions.
I would like to thank you all very much, for your kind and warm comments.
Best regards. Find.
hej et forslag til video, jeg ser mange ønsker at se en video hvor du bygger en at dine motorer , man kunne nøjes med de mest intressante ting, og tage det over flere videoer, hilsner fra klemensker
Hej Find. Jeg tror at mange af dine følgere, ville være vilde med at se, hvordan du bygger dine maskiner.
Fantastic! I cannot begin to understand the work that went into that engine but I can see it was huge. So much detail, everything done so well. You are a fine engineer sir and the safety valve is simple Genius. A very impressive engine and concept with the valve. If I had 10% of your skills and Smarts I'd be a very happy man. Thanks for showing us this.
Completely agree... these engines are amazing; Find is truly a master craftsman. Long time no see, as a subscriber to your channel as well!
Your Engines and Tools are Amazing, i just wish you would show more Machining and Building of them. Superb Craftsmanship.
Very sweet! How many liters per week does it use? I could listen to that idling forever! BTW, that's one Diesel that WILL fit in my Honda! LOL. (Old joke).
Mighty car mods!
@@roastingpeanuts some guys made a car run off of a weed eater motor lmao
@@yeet3071 There's a lot of videos of people putting weedeater carbs on like 302 v8's & stuff too
Absolutely beautiful work. And thank you for taking the time to share it with us.
Find, A very beautiful and well running engine. You did a fantastic build. Thank You 👍
Jim 👍
I am always fascinated by how the fuel injection system is so precise and controllable by the governor.
This is the ultimate mix of art and engineering. Gorgeous!!
I think there should be a gallery of such machines on display for people like us. Does anyone know if such a place exists?
@@Goaterd Yes. Type in "Find Hansen"
Beautiful engine. Thank you for sharing it! The large Caterpillar 3600 series engines I work on have cylinder pressure safety valves similar to this. Very good idea!
His voice is louder than his diesel engine, amazing.
I've said it before and I'll say it again, your engines are true mechanical works of art!
A combustion engine is really cool from a mechanical point of view. I hope they'll survive by use of synthetic fuels.
I hope they’ll survive by use of renewable fuels such as bio-diesel
@@Goaterd peanut oil. Which I believe was used in early diesel engines.
It's a peaceful sound.
Such beautiful work and a fine model! Thanks for sharing this. Wishing I had the skill and talent to do such works!
A creation of absolute beauty embodied, you are an inspiration.
The workmanship is amazing. I'd love to have something like this some day
What craftsmanship, you are truly craftsman
Incredible workmanship. Thankyou for sharing
That is a beautifully crafted engine. Nicely done!
Your accent is superb & the knowledge your presenting is awesome! Ty friend!
You did a beautiful job building this!
A beautiful piece of work that runs superbly. Thank you for sharing with us.
Gorgeous engine. Interesting presentation! Thanks for this.
Could you upload a video showing or discussing the build process? Also would be cool if you built something for it to power. Extraordinary!
I am in awe of your machines, every time. You are a true master!
Wonderful, your engines and craftsmanship are fantastic.
Great looking engine Find! thanks for the insight.
What a work of art Sr and amazing craftsmanship would live to see any build videos if it.
Beautiful craftsmanship and mechanics.
Beautiful fine running engine. Good work as always.
An exquisite work of Art!
Great video, love those small engines, always fascinate me to look att while it is running.
Gday, absolutely beautiful engine, thanks very much for sharing, cheers
Absolutely gorgeous engine and craftsmanship.
What a beautiful piece of engineering that is. All engineered to work well and look good - I agree that flywheel is particularly nice. And very interesting to hear the rough calculations of the forces involved - much bigger than I would have guessed. I bet that flywheel escape got your attention, I suppose it's fortunate that it isn't typically very high revs, but still quite a bit of mass and energy to let loose in the workshop. Thank you for posting.
Thank you Mr Hansen, I really enjoyed this video
Well done for the video thanks for sharing. Amazing as always.
Beautifully built engine. You are a true craftsman.
Thank you for sharing your experience and knowledge with us. :-)
hy Find ! thank you for the Help with the Oil can ! please keep the videos comng ! we all love them so much !
Such a beautiful little machine!
Thank you.
Wow.. an amazing piece of precision engineering... It runs very sweetly. starts very easily..
Wieder ein Meisterstück. Von so einer Kompression kann ich nur träumen mit meiner Bohrmaschine als Bearbeitungszentrum. Sehr schöner Motor.
I really love your engines. Beautiful works of art, and full of clever little inventions -- like this safety valve.
That's a really beautiful engine, thanks for sharing:-)
A beautiful engine built by the man who is running it, what better praise for the man. Thank you for sharing.
That was very interesting well done . Thank you for sharing
Runs superbly, music to the ears!
SO HAPPY TO HEAR YOU AGAIN!!!!!
Very interesting!
Beautiful engine you made!
Thank you for posting! Seems like ancient history now, but in the 70's & 80's small kit engines were still made in the USA. Gasoline & steam powered were most common. Diesels weren't easy to find, but still available. This was to teach school children the basics of internal combustion engines, & inspire a new generation of future engineers... My personal experience as a child was with gas powered model airplane engines, & the Capsela modular toy set, from which a variety of cars, bulldozers, & boats could be built. Also water pump, air pump, for model aquaduct & water reservoirs to be built in a sandbox or terrarium
You can still find steam models, and glow and gas engine powered models are still around but certainly sold as "big boys toys". While IC power will always have a place in certain models it has largely been replaced by electric, brushless when you need all out power and brushed for when you need fine control of speed. Also small scale aeronautics has gone full high tech with FPV UAV's both winged and multirotor. Engine models like the one in this video are finely crafted pieces by a small handful of people, mostly retired machinists and mechanics that have dedicated themselves to making running art!
@@chrisegan7537 A hundred thank you's for your reply, Chris! I haven't thought about small scale model engines in 40 years. And the only reason it came to mind in the 1st place was my stumbling across this video. Cheers! 💜
@@chrisegan7537 Miniature jets have been around awhile now. But they're still very new to me. Here's a model aircraft exposition from germany I just found lastnight. I think you'll enjoy it. It has a couple of stealth SR-71's, & a VERY large F-series fighter jet. F14? F16? I could tell as a kid, but not anymore. Enjoy!

@@magnificentmuttley154 Model jets are cool, but I'm trying to find one of the OS glow rotary engines (like in a Mazda) to adapt to a tether car or RC car.
ANOTHER super, interesting model and demo !! VERY many thanks !!
Beautiful work you do.
This is very cool, thank you for sharing this!
Your projects are always immaculate, when do you have the time? :-)
The safety valve you have fitted was often fitted to old diesel engines in the early 20th century, it was not intended for over speed protection but for cylinder overpressure limiting to prevent blowing of head gaskets or in extreme situations cylinder liners splitting in high load conditions. Early gaskets and metallurgy had their weaknesses.
A positive way to stop an overspeeding engine that was used by General Motors on their 2 stroke diesels was to have a spring loaded flap in the air inlet duct, the flap was held open by a cam and pawl, in an overspeed the pawl was lifted allowing the cam and flap to rotate and close the air inlet, it was a last resort stop as the high negative pressures developed in the inlet duct could draw the oil seals out of the Rootes blowers.
Love your projects.
A very fine working Compression Ignition Engine model and demonstration the pressure relief valve function, very great job and highly respected machine works.
Wonderfull, Your engines makes me calm and happy, it is so nice to se the craftmanship in what you do. My hands have let me down, so I have to enjoy other peoples work. Thank you. ;o)
Again a wonderful video. My hat off to you sir.
Fascinating,,,,Thank-you for the video.
Love these engines.
Thank you for your film. Very interesting indeed.

It is nice to see this model engine channel can get 50k views on a video in a month.
It's amazing , you are so hardworking and creative sir thanks for making the video
Brilliant, thanks for sharing!
Once you did a close up wow what beauty
Just something great about any engine with a governor.
I always wanted to use one of these to trickle charge batteries
Und wieder ein tolles Video von einem tollen Motor und einem Genius, der ihn geschaffen hat.
Gefällt mir sehr, tolle Arbeit. Danke fürs zeigen.

You're back!
Thank you Mr Hansen 👍
Marvelous machining
wonderful engine you must be very proud of this beauty
Work of art.!!
I wonder if Herr Diesel had any such runaways ?
A thing off great beauty sir .
thanks for sharing keep up the good work.
Gorgeous as usual
Awesome, a small dynamo to power a light is all I would need with that , thank you
👏👏👏👏👏👏👏👏👏👏Simply Beautiful!! Congrats!!
Beautiful work.
On a side note…you could easily make your own espresso machine…funny how much of our modern conveniences tech overlap.
Me encantan sus inventos ,lo felicito
Smukt håndværk, og godt med sikkerhed :-)
Herzliche Grüße aus Österreich!
Greetings from Austria!
👍 Danke fürs Hochladen!
👍 Thanks for uploading!
👍 Very good and beautiful, thank you!
👍 Sehr gut und schön, danke!
Would be interesting to put a belt driving a generator on it and see how many watts it can produce before stall. It'd be fun to see if such hobby engines produce enough power to still be useful.
I do a lot of restoration work on 18th century verge fusee watches. Would like to attempt building one of these.
A beautiful engine. Would be great to run a generator.
fantastic engine
very neat thankyou for sharing! where did you start this hobby? where to get started with mini diesel engines?
Beautiful.
Another way could be adapt the adjustment handle for the compression, so if a runway occurs, you can stop the compression and so it stops the engine? I noticed that even with the safety valve opening, the engine still gains speed.
Absolutely fantastic! Would love to see the in real.
Hello Hanson,I’m currently attempting a 2 cylinder diesel, amazing work you doing, what Center lobe angle and duration did you use on camshaft? Thanks
Beautiful
I never would have put a safety valve on an engine like this. Mostly I just wouldn't have thought it necessary. It does make a certain sense here though
Beauty of an engine, do you run straight kerosene/lamp oil or do you add a little bit of lube to the fuel mix?
