That is one of the coolest things I have ever seen,

That was cool! Any idea on what V12 design it was based upon?

Very, very cool.

1. I wonder what kind of fuel it uses.
2. I wonder how long you can run it before it gets too hot or needs to be re-oiled.

That thing is sweet. I used to be into remote-control cars with gas engines. They were single-cylinder and ran off alcohol fuel (20% nitro-meth too). Tons of power produced out of something so small.

^^^ Yeah, I was thinking a mix of Nitro-methane.

When I was a kid, my best friend was into those nitro powered cars. Those things were stupid fast.

Didn't notice any gasket material or out of a tube... His tolerances must be tight.

Love to buy a basic kit like this to build with my little one.

Looked like it was being 'motored' on compressed air (no ignition) so no combustion, and no heat.

Without pressure oiling, i'd squirt the hell out of everything after each run.

Cam gears were 1:1, not 2:1, so every downstroke was a power stroke.

Either a 2-stroke diesel (note the lack of spark plugs, ignition system, etc.) or as aircarver says, "powered" by compressed air. Don't know which, but if I put all that work into such a beautiful machine it would actually run on its own.

Still... what a gorgeous labor of love. :cool:

I work on Locomotives for a living, that's just amazing. Exactly what I do on a much smaller scale.

.

The smallest engines have always been the CO2 type (compressed air). Below a certain cylinder size, thermal efficiency gets so bad that fuel burning engines have too much trouble keeping themselves warm enough to run well.

In tiny engines, the ratio of cylinder surface area to cylinder volume is such that you have too much cold metal sucking the heat right out of your working gases and taking all the pressure away before the piston gets a chance to move in respond to the pressure. Just like the reason why a thousand tiny ice cubes melt faster than the same amount of ice in one large chunk.

Still cool, but it don't burn fuel.

Looks sort of like a GE -9 FDL engine, but if it's a two stroke it could be modeled off of an EMD.

Compressed air

2. I wonder how long you can run it before it gets too hot or needs to be re-oiled.

Since there is no combustion taking place in the cylinders, probably a long time

Ergo: it's not an engine, but a motor ...

From the youtube link: "v-12 engine with compressed air injection,hand made using taditional methods:12 cm3 of displacement,the diameter of the cyllinder is 11,3 mm,the stroke of the pistons 10mm,it works with only 0,1kg/cm2.Is constructed with stainless steel,aluminum and bronze.Patelo dedicate this engine to his grandchildren:Sara,Carmen,Jose and Pablo.This engine is for education,exhibitons,etc.,that is the reason to work with compressed air, to avoid contamination.He has made the plans and all parts, except the screws.The engine is not for sale.Thanks to everybody for the comments and sorry for my bad English."

Very true........seems some an unfamiliar with the definition.
