We know a lot about toggling bits in a register, however only a bit about how engines work. this one inspires us to throw ourselves into the field with reckless abandon. [Huib Visser] built this glass cylinder four-stroke engine as well as he took terrific care to make it beautiful. We don’t need our projects to be polished as well as gleaming, however we have to admit that this the opposite of what we see when popping the hood on our 12-year-old rust bucket out front.
You can’t see it in this image, however just on the other side of the fly-wheel is a smaller wheel with a cord wrapped around it that acts as the pull start. This gets the toothed timing belt going along with the cylinder. As part of the demo video we get a good look at how the rotary intake as well as exhaust valves work. [Huib] likewise took the time to demonstrate how the rare earth magnets as well as hall impact sensor reed switch synchronize the ignition system.
You won’t want to miss the end of the video which show it in action as It burns Coleman fuel (white gas) as well as is lubricated with WD-40. This is jaw dropping as well as it works like a charm, however still not that far removed from the concepts seen in [Lou’s] hardware store engine project.
UPDATE: Here’s write up this engine (translated) [Thanks ChalkBored]
