    I have always had a long-term fascination with innovative alternative engine designs.
    Thanks to a bumper crop of talented CAD designers, the web is full of mesmerizing animations.
    Some are almost hypnotic. Enjoy...

    Friend of mine built one of these back in the '80s.

    Very Cool! I wonder if Coates has gotten anywhere with this stuff...

    Ah, yes, the spherical rotary valves.
    Their animation won't imbed, so you have to click on these links:

    Here's a 100 CuIn Harley with the Coates valve system.

    You've already posted two versions of the Duke Engine but here is another video of it.

    Neat application that will run on existing OHC short block designs. Been following this one for a while.

    A little more on Free Valve Technology

    I love it! Variable-valve, free-valve tech was mostly concept and pipe dream back in the '80s. Was hoping to live long enuff to see this stuff come to fruition...

    I like the looks of this single pin crank engine.
    I'll bet it has lots of tourque

    I took a VW VR6 apart one time. I realized quickly that even if I wanted to I wouldn't be able to bore it because the boring bar I was using referenced off the deck and the cylinders weren't 90 degrees to the deck. Besides, the cylinders may have been Nikasil, I can't remember. Also, how often do you see a 14 degree V6 with one cylinder head? Nuts!

    Oh, yeah. As much as I appreciate and admire these innovative designs, there's no way I could afford the exotic tooling to work on them.
