Hey Luuuxers :)
It is Spanish and was built from scratch at home.
For all those who, like me, appreciate the art of engine design, will be impressed with the creation of Spanish engineer named Patelo.
The creation took about 1200 hours. The time required to design and build all parts of the root. Engineers named the project "Probably the world`s smallest V12."
The engine works by compressed air and has a total capacity of 13 cubic centimeters. Built as an educational project, has 261 pieces of bronze, aluminum and stainless steel.
