“World’s Smallest” Working V-12 Motor

“World’s Smallest” Working V-12 Motor

A Spanish craftsman named Patelo skillfully designed and fabricated this tiny working V-12 motor from stock stainless steel, aluminum, and bronze for his grandchildren Sara, Carmen, Jose and Pablo. It took more than 1200 hours of work. Not counting the 222 screws, he machined all 261 pieces himself. The engine operates via compressed-air injection, has 12cm3 total displacement, 11.3mm cylinder heads, and a 10mm stroke on each piston.
