This is a video of the world's tiniest V-12 engine being made by hand-built craftsmanship. Now the video does not say this, but I'm guessing the motor works off compression ignition like a diesel. Which would be similar to the way an R/C car that runs on gas. This would explain why their is no lubricant added to the engine. The lubricant is in the fuel. It has 12 cm^3 of displacement, the cylinder bore is 11.3 mm and stroke of the pistons is 10 mm. Works with just 0.1 Kg/cm^2. It is constructed of stainless steel, aluminum and bronze. The creator is Patelo who dedicated the engine to his 4 oldest grandchildren: Sara, Carmen, Jose and Paul.
Giszmag - Anyone who appreciates the precision art of engine design ought to get a kick out of this offering from a Spanish engineer named Patelo. Starting with hunks of aluminum, bronze and stainless steel, he spent over 1200 hours designing, milling, turning and drilling what he claims is "probably" the world's smallest V12 engine. Powered by compressed air injection (0.1kg/sq cm), this little marvel boasts a total displacement of 12 cubic centimeters from its twelve 11.3 mm diameter pistons and works like a charm.
Built primarily for educational purposes, Patelo has no plans for selling the mini-motors. In fact, seemingly to prove this lengthy exercise in metallic accuracy was truly a labor of love, he dedicated the engine to his four grandchildren. He crafted all 261 pieces of the engine from scratch, but drew the line with the 222 screws, which he purchased, presumably so he'd have at least a little time to spend with the grandkids.


What a totally cool idea. Now he just has to build the car around it, and he'll have a working miniature car. Probably worth thousands. I would love to see that.
It's running off of compressed air.
Awesome. Great work, and unbelievable patience. I would love to see a straight 6 cylinder, OverHead Cam (OHC), vintage 1968 Pontiac motor division. An incredibly powerful 6 cylinder engine.
