Scary amazing! Notice how fast that exhaust valve closes each time? So fast the time-lapse camera doesn't even pick up the movement. I wonder what cam that thing is using. Also, I noticed the degrees of rotation are running at the bottom. Beats the hell out of a degreeing wheel!!!!
Awesome videos! The rotory engine looks like the pieces from the "Spirograph" toy I had in the '70's!
Hell yeah Spirograph! Kids don't know what they're missing these days. I think I'm gonna get one for my boy actually...
In VoTech my teacher had a single glass cylinder 4-stroke. It was neat to watch run. Thanks for the vids!
i just found that inside the cyl video just yesterday while looking at a resto video in a mustangmedic.com
The video clip stops partway through the exhaust stroke and re-starts at the beginning. That's why you don't see it close.
