Found this on another site and thought I'd share. Pretty cool stuff.

Great video. Not what I had imagined. thanks for sharing

This was posted a couple months ago, still a cool vid.

This is cool!!!

That is cool. I wish that they showed the entire cycle, instead of just the ignition cycle.

I would have thought it would be more violent with more fire.
Thanks Eric it was really cool though.

No valve overlap at all?? I thought you wanted some valve overlap to help pull in the intake charge. Maybe this was a tractor or some industrial motor?

If there is any overlap you don't see it. The clip is missing the part of the exhaust valve fully closing and intake valve beginning to open.

You can't see the exhaust valve close, but you can see the complete intake valve sequence and the exhaust appears closed at the very start.
