Strange but simple engine.

Hi Guys

I found a series of very interesting you tube videos showing internal combustion engines of very simple design and build (see link below), I am convinced that one would be able to build some of them without even using a lathe.
It appears to be some type of non compression engine, obviously the intake will be a atmospheric valve but what about the exhaust, sleeve port perhaps? any ideas from you guys?
I believe this design will be ideal for a first time model engine builder, it is simple and if it runs it is sure to inspire some more builds.

Interesting engines....but unfortunately, I can't read German...so I have no clue just how these self-built engines work.

Thanks for the links.

Hey RussellT,

check out the valve/carburetor on the third video!

RussellT:
That's a very similar action to my mod up engine but I think only one set of ports :scratch:.  It doesn't use the screw thread retainer though.

It's quite an interesting design because it does simplify some things.  For example it seems to use the same port for inlet and exhaust and the carburation is more akin to direct injection, but I don't understand the whole engine - it doesn't have a compression chamber so my initial thought was 4 stroke, but the ports don't seem to allow a 4 stroke cycle. :scratch:

I can't read German - can anyone out there translate for us?

I love the fact that a single piece of pipe is air intake, carb, valve, and pivot.
