    Couple of things I haven't seen mentioned in depth.

    One is the electrical turbocharger needed to get this running, a blown two stoke will not start unless it has a source of boost air. Most of the known designs Commer, Junkers etc use superchargers which also use a lot of power.

    Second thing is noise, anyone who has anything to do with these engines knows how noisy they are as regards exhaust.

    On the Commer the two exhaust boxes were literally the size of the engine, not a problem on a truck, you usually have much unused space around the chassis but other applications could seriously limit this.

    Personally I don't like the design, too many moving parts to wear out / cause problems but it's just the sort of design if well presented to fish for military funding money.

      BUT every engine manufacturer is set up to design and build ottoman 4 stroke motors... The know after 100 years that if you do x you get y...

      They are not going to start a new design when there is no need to...

      I think you are getting your Ottoman Empire mixed up with the Otto cycle engine.

        If you want "simple" have a look at the Napier Deltic engine

        & working ->

        Interesting info here -

        I used to be indecisive. Now I'm not so sure , but I'm not a complete idiot - some bits are still missing

          I didn't watch the whole video to see the valve system, but here is an old example of an opposed balanced engine. It ran a hay press, and it's called teh Lightning.
