    HUSA,
    Slow down mate, feed it in slowly - it's very interesting of course, but we need time to study it all and try to digest everything!!

    The Karol Ansdale Engine.
    Obviously the design wasn't finalised and up and running, possibly not even reaching the prototype stage. There is no sign of it on the net that I can find but this has been taken from a very old scrapbook I had tucked away.
    Having had a quick look again, I can see that I hadn't sat down all those years ago and thought about the concept thoroughly enough to properly understand it !
    Looking quickly at it again (after a lot of years), I feel that the surface speeds (at the sealing surfaces) may be have been too high, then again maybe not because the section containing the pistons/cylinders probably rotate at half speed. Got to study it more myself!

    I are pretty sure it is a uniflow design like this one, Neil Hintz did.

    Is that one using O ring seals as opposed to head gaskets?

    Being quite new to the scene, I had no idea that Neil had a uniflow engine actually in a bike! - guess he's tried everything possible, that's over 20 years at least - still as keen as ever - remarkable!

    I was hoping Neil would share a little it had conrods and pistons from a weedeater I think.
    From what I understand they had to stop the racing as the homemade ignition interfering with the Ohaka bases electronic equipment.

    You only need head gaskets if a head is fitted, so maybe they are base gaskets
    My neighbours diary says I have boundary issues

    Commer TS3

    "The engine was unusual in being an opposed piston engine where each horizontal cylinder contains two pistons, one at each end, that move in opposition to each other.[5] Even more unusually, both sets of pistons drove only a single crankshaft; most opposed piston engines have a separate crankshaft at each end of the cylinder. The TS3 engine used a single crankshaft beneath the cylinders, each piston driving it through a connecting rod, a rocker lever and a second connecting rod. The crankshaft had six crankpins and there were six rockers.[6]
    The engine was a two-stroke, compression-ignition diesel engine with uniflow-ported cylinders.[6] Scavenging was performed by a Roots blower.[7] and was mounted on the front of the engine and driven by a long quill shaft from a chain drive at the rear of the engine. Although the engines gained a reputation for good performance, this quill shaft was somewhat prone to breaking if over-worked."

    True that. I made that assumption because the piston crowns were facing that way. And I guess I am used to seeing a head on TOP or SIDE of an engine.

    I think I watched either that one or a TS4 on low gear, was very interesting.

    Dads got on in the back yard, it has some patents on either the block or the supercharger relating to Kadencey as in Michel Kadenacy

    Below Honda EXP2 fuel injected but created autoignition to clean up exhausts it used a trapping valve
