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.



I remember reading eon's ago McCulloch had worked on such an engine, I never
could find a picture of it until I found these two links after a quick
search. Is this it, or am I way off here?

Yep that looks like it. A picture on the front of Pop Sci is the kiss of
death.

Yet another diesel aircraft engine bites the dust :)
Hope springs eternal :)

What is it about power to weight ratio aircraft diesel engine fans do not understand? :)
Perhaps they think airplanes fly on torque :)
