Lets you see exactly how the inlet valve opens, letting the air/fuel mix into the combustion chamber, with the piston going down getting a vacuum which helps draw the mixture into the chamber. The piston then rises again, compressing the mixture, and under compression, and with the spark from the spark plug the mixture ignites, just as the piston starts going down again. The exhaust valve then opens, just as the piston begins to rise, pushing the exhaust gases out into the exhaust system.

Nope but the flame front does - it really hangs on to all surfaces especially the inlet valve doesn't it?
Shame it's not an A. You can see how a hot plug could cause detonation!

That is pretty amazing i like the way you can see the spark before tdc and the combustion start would be great to see it on different state tune engines like cam overlap

That is proper cool! Agree - would be cool to see some overlap. I also was surprised at how the flames seem to hand around the edges!!
