Unreal.

Enjoy. I sure did.

Very, very cool.

Lots of questions:

Ignition? Did not see any plugs or wires, assume it must be sort of
a quasi diesel like a model airplane engine.

Lubrication? No sign of a pressurized lube system so assume it must
be done by hand.

It would take the patience and skill of a swiss watch maker to build
something like that. I wonder how many man hours.

It was fascinating to watch the crank shaft being turned using an off
center billet. Incredible precision involved for that and the cam
shafts.

Gene Kearns would appreciate this if he is still lurking under another
name. He'd need to downsize that 20 ft lathe of his by just a bit.


I know where Gene is, I think he has seen it by now... As to the
"ignition", it really looks to me like it is run on compressed air, no
ignition system, no carb, no plugs, no battery, no fuel rails..... One
plastic line coming in, I assume it's pressurized air

Deisel?


I dunno, the cylinders are tight but there are no compression rings. I
still don't think it's internal combustinon... No glow plugs either...

You're probably right about the compressed air, hadn't thought of
that.

I second the compressed air idea. If you could see the cam timing a
little better it would be easy to figure out. A compressed air machine
would be a 2 stroke with the intake valve opening around TDC and the
exhaust valve opening on the compression stroke. Pretty much a
compressor running backward.

Or a steam engine.

That same engine vid is on Youtube

http://www.youtube.com/watch?v=3YfTt...ature=youtu.be

And in English the description says:

"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."

So, now we know...

Solves that problem. Thanks, Tim.

There's no piston rings on a cox .049 model air plane engine either.
but those cool little glow plug fired diesels and their nitro-methane
blend fuel take care of their own.

You could be right, I'm going to watch it again, but you don't need glow
plugs to fire off a fuel and air mixture. Just compression.
