3D Printed V8 Engine Uses Solenoids

Normally when you think of a V8 engine you think of pistons driven by exploding fuel, pushing a crankshaft. [Miller’s Planet’s] version doesn’t use pistons, instead it uses solenoids along with a 3D printed crankshaft. The finished product would make a great science project or classroom demonstration of how a crankshaft converts a reciprocal linear motion into a rotary motion.

There are a lot of 3D printed parts and the links are in the post. A lot of the video (see below) is filmed in the wordless-workshop style with just a few text overlays to explain what is happening. But towards the middle, you’ll hear an explanation of how a solenoid produces force. The real payoff though is at the end, when you get to watch the contraption in motion.
