    Interesting to see the inside of combustion chamber

    Thanks for Sharing, very interresting

    Unfortunately I cant see the video here at work. Is it that video of the 4 valve engine thats been floating around youtube and such? If it Is, I just happen to know the engine.
    Ok Now I can see it being on the home computer, yep I know the engine....I worked on it!

    Any idea how the video was captured?
    Of course, High speed digital photography thats crank angle triggered. Im not allowed to divulge specifics however as its considered " intellectual property" by my employer, everything we do in engineering is. We have to jump through all sorts of hoops to share some things at confrences. Oh well. Enjoy!

    Looks to be a bore-scope with a high speed camera on the end of it. Gotta be a tad difficult to prevent carbon buildup on the viewing port, which I'd hazard a guess is quartz or some incredibly clear pyrex.

    Excellent video, at any rate. Shows the relationship between valve operation, piston position, and ignition timing. Looked like a multi-spark ignition, too.

    Nope. Single spark event.
