I’m going to have to send off for one of those window kits for my engine! No more wondering, “Does it have spark? Does it have fuel?”. ---

What other valves? There’s an intake and an exhaust valve. What else is needed? There are still some two-valve-per-cylinder engines around. ---

Wow, that is really cool. What were you searching for when you found that? ---

Cool, but I wonder why the video only shows three of the four strokes. The frame skips past the exhaust stroke and goes directly to the intake stroke. ---

They’ve actually been doing this for many years. I think the first time I saw a film about this was about 30+ years ago. The coolest thing I’ve seen was an R-4360 (yep, 71+ Liters) 28 cylinder radial aircraft engine that had been converted into a rotating, cut-away display model. Near 2 tons worth. It was absolutely beautiful to look at and utterly amazing to watch all of those internals while they were rotating. ---
