I watch this and think two things...
1. Is it fake? Something just doesn't seem right? I guess I am looking for a more controlled burn as well as it seems like it is pulling more air/fuel into the cyl than I would expect. I also don't understand why the camera seems to vibrate around as much as it does. I can imagine it vibrating due to the engine operation, but it seems to be vibrating at a rate higher than the apparent RPM of the engine. But maybe it is shockwaves in the block/head that are causing it.
2. It probably is real and maybe it is just challenging my pre-conceptions?
Related video that is pretty cool. Shows animated construction as well as operation of a 4-cyl, 16-valve, DOHC 4-cycle engine.
