World smallest v12 engine

The tiny polished V-12 engine features 12 cm3 of displacement with 11.3 mm cylinders and the stroke of the pistons 10mm. It runs on compressed air though it could be possibly running on gas but the machinist didn’t want to contaminate the air with combustion gasses. The Spanish machinist render 1,220 hours to complete the mini-V12 engine that includes tedious machining of 261 parts and 222 screws all in all. It’s one of the most delicate and detail-oriented creation of an engine we’ve seen so far, it is not for sale, –it’s  the machinist way to instruct viewers on the inner workings of such an engine.
