World’s Smallest V-12 Engine Made By A Spanish Engineer (Video)

After 1200 hours of designing and crafting the world’s smallest V12 engine, Spanish engineer, Patelo, finally has something to show all of the automotive fanatics in the world. Built entirely from scrap pieces and some large materials, the engine is powered by compressed air injection. The twelve 11.3mm pistons are capable of producing a displacement of 12 cubic cm.


This motor isn’t for sell though since Patelo is doing this just for fun and education. The one pictured here is slated to be given to his grandchildren.

Few more pictures are given below:
