Hi Paul. Did was there ever version of diesel rotary? Thanks.

Not so far.

Is it possible for me to order a custom made rotor with compression
ratio of 18:1? I could come up with way to adapt pump and injectors
to it. The biggest concern with diesel is the turbulent of the
combustion chamber however. Do you think the rotor action can make
complete fuel burnt possible? Do you see any draw back with a diesel
rotary base on the 13b? Thanks.

Not possible. A depression in the rotor face is necessary to allow
combustion.

I guess that also from purely geometrical reasons, a single stage
Wankel RCE can't attain such a high CR, the top limit is described
somewhere, but I don't remember where; anyway, there's an old photo
of people in MAN machining a very big size rotor, that If I remember
well has no or little combustion recess. In the 1981 K Yamamoto book?
In the 'Wankel motor und sein erfinder' site? Thanks for your
attention. Best regards. Salut

Jose,

It appears the rotor in the first pic is still being machined, looks
like a giant lathe behind it. The rotor being placed in the housing
the second pic very clearly has a large and long depression, much
larger than Mazda's.

Mr Paul and friends.

I think just about compression ratio. turbo charger easily make it
possible.

for me I just considering engine as generator. it's also extremely
easier.

and I also think about extra piston at intake side. because Rotary
engine's intake part never get pressure.

so It's very easy to put an extra device on that. so It easily adding
much more copress ratio and much more air intake easily.

Not just rotating rotor we can install additional air sucking
mechanism at engine.

I will show or upload video in future. after some time.

Hello again!: I've found that the German company
www.wankelsupertec.de <http://www.wankelsupertec.de is developing a
RCE able to run on Diesel fuel. Have a good week, best regards.

They have been around for years and so far I have not seen or heard
of one running. Fantastic claims with no hardware demonstrated. A lot
like RPI.

So here is my question: is it possible to set up a reburn system so
one charge gets ignited over two engine cycle?  So the second burn
would be like the old Honda CVCC lean burn system on the second one?
Perhaps add a rich squirt to do the second burn?

It has been experimented with but so far no production engines.
One cycle pre chamber. Two engine cycles not possible with the Wankel config.
