Tiny 12ml V12 engine... speechless

[e46_UDM]

(source: http://cbt.com.my)Not everyone can build an internal combustion engine, let alone one as complicated as a V12 engine. Or completely machine the components and hand assemble one that has only 12ml of displacement. Mind you that is a 0.012-litre V12 engine, the cylinder bore is only 11.3mm and the stroke is just 10mm. The engine is made from aluminium, stainless steel, and bronze, comprises of 261 parts, screwed together by 222 screws, and took 1,220 hours to build. It isn't just some mere static model to serve as the ultimate engineer's paperweight, as later in the video the engine is show running with all of its 24 valves buzzing like a metallic bug. Enjoy!

Great construction video but that's still pneumatic, this is internal combustion.
