Dear Paul and Others,

I am in the process of building a Pietenpol aircraft and, as such,
am a member of a Pietenpol Forum of builders. A member recently
posted the attached pictures and asked if anyone could ID the
engine. Can you help? Is it a rotary engine? I am not sure if he is
interested in putting a rotary engine on a Pietenpol, but he asked.
I know that the Pietenpol may have the distinction of having had
more choices of powerplants  than any other aircraft. Over 30
different engines have been documented. Do you know of any builders
that hung a rotary engine on a Pietenpol? I would be interested to
know and will, of course, pass the information along to the other
Pietenpol builders. Thanks in advance for any information provided.

Looks like a seven cylinder liquid cooled radial.

Perhaps 2 cycle. Could be sleeve valve.

A one rotor would make a great Pietenpol engine.

The silvery thing with a black filter canister above it and another
one to the right of it looks a lot like a diesel injection pump ?????????

And is that a 6 loop V-belt reduction drive????????

Apparently, it's a five cylinder turbodiesel radial engine.  Never
seen before. A fake?  EB.



It could be mechanical gasoline injection.
