Amaciammmmm... I like this pic because it prompts peeps into believing that the engine is carefully drawn. Of course lah, in actual fact, it isn't. The real pic involves intricate and incomprehensible engine parts; but that is just not my forte. If got AutoCAD or Pro-E software then can ah, but even so, I'm not good with it.
I merely filled that up with random shapes and toning to make it look as such. Haha bet you all got fooled by that don't ya??
