Heavy fuel means it burns diesel but it is not a true diesel.
Power is down from burning gasoline so it makes no sense with the
intrinsic increased cost of diesel fuel.

BTW Do you have a tail dragger training FPO up there Rob?

Hi Paul,

Not near here (I'm in Porterville South Africa - it's near Cape Town).

There are two centres which teach on tail draggers about an hour's drive away.

I became very interested in rotary engines some years back, when I considered buying the
Sinus from Pipistrel in Slovenia. Unfortunately, the factory will only fit ROTAX engines; and
won't even consider any other option as a factory fit. I hoped at the time that the power plant
from Wankel itself might persuade them to look at the idea, but I don't need to tell you what
response I got...

...not helped at all by Wankel's neglecting (then and now) to answer any of my queries.

Anyway, back to the drawing board. I don't really want to do a self-build-from-scratch, but it appears that I might have no option.

"Heavy Fuel" apparently refers to Jet A1, which (probably) requires a spark - not, as I
supposed, to diesel. I wonder whether diesel would ignite "normally"..?

Thanks for the chat-list - I found it during my search for rotary answers.

Very helpful, informative and entertaining.

Rob


What a coincidence. We have a Porterville here in SoCal.

They are rumored to be working on a two rotor.
Austro engines is also working a 75 HP one rotor for motor gliders.
None diesel burning as it is difficult to get the required compression
ratio with the current Wankel geometry.
