World's tiniest V-12

Video, 9:25

Pretty cool. Nice machining. Too bad I don't read the language the captions are in. It doesn't seem to have a lubrication system. Not sure about cooling.

I don't see the ignition system. Assuming its real, how is it firing?

[Johnny L.A.]

You know, that did occur to me when I watched it earlier today. It slipped my mind when I posted. Maybe compression is high enough to provide sufficient heat for ignition? It does have a 'tapa de distribucion', which is 'distributor cover' in Spanish. But it must mean something other than what 'distributor' means here.

Once again I misread the thread title. I though it said V-2 and was wondering if you had enough of them could you blitz someone.

This article says it runs on compressed air and provides translations of the captions.

Amazing craftsmanship.

While a remarkable feat of engineer and love, I don't think it's the smallest V-12.
I didn't see any size measurements on that engine, but a Czech manufacturer, Gasparin, has been building CO2 powered engines for many years, they have a V-12 measuring a mere 72mm in length (a little over half the diameter of a DVD to give an idea). And you can buy it for a mere 1300 bucks or so.. Here's a video of one doing its thing.
The rotary motors are awesome too.

Gasparin also built, IIRC, the smallest piston engine ever with a displacement of one cubic millimeter.

The extra cool thing is that this motors are meant to be mounted in flying models, so for example you can have a pigeon sized Red Baron Fokker triplane with a working rotating radial engine.
Years ago I remember mulling over the idea of buying one (the cheaper single cylinder type) for one of my free flight airmodels, but never did.

I gotta say that is the worst music in history for engineering demonstration, it just really wrecks the video. For a movie epilog good, a bunch of Lathing, horrible.

I had a small single-cylinder CO₂-powered motor as a teenager. I never could get the thing to work for more than a few seconds. It's too bad that the V-12 isn't ICE. It's an amazing feat of craftsmanship, but I can't help thinking that there are a whole lot of parts moving that don't need to be moving and adding their weight. (Not the point, of course; just how I think.)

Someone on Runner Pat's link posted a link to a small V-12 ICE. Here's the page via Google Translate.

pshaw!!!!!
that v-12 is just a child's toy! and it sounds like one when it's running.Little tapetty-tap-tap sounds.
Plus, it only took 1220 hours of work.

Now, if you wanna see a really impressive miniature v-12 engine, built into an ASTOUNDINGLY impressive, fully functioning and perfectly accurate miniature Ferari, take a look at this.

and listen to it roar......

The hobbyist who built it says it took 20 thousand hours.

You just have to stand back, and tip your hat in awe at some people's dedication.....
The first video is pretty damn good. But the second one just blows me away.

I was just going to post that one. It's a 103cc fully functional hand built Ferrari V-12 race engine. It produces 8 hp at 10,500 rpm!

Here's a page with additional info and photos:

Here's the builder's web site. It also covers the other cars he's working on:
