Hey all,

This japanese guy I work with at Delphi had all of these cool technical
books written in japanese and I found this on rotary engines. I though
it was pretty cool so I decided to share. Diagrams look standard fare
but there may be some info in the words that are useful. Doug?
I do have a question about the diagram on page 19. You can see the rotor
housing is straight on the old version and v shaped on the newer
version. Just for weight or is there a flow benefit to this. Also you
can see that water chamber on the side housings are different. Same
question.

Here are a couple of screen shots on Rob's doc pdf.

Rob,

These pages talk about the coating technology which was 'new' then.   A
fluorine polymer coating over the stainless steel housing.

As to your housing question perhaps it is talked about on the next page.

My guess is the fluid dynamics as well as the housing strength is better
on the right hand current 13B rotor housings.  Stronger because of the
truss shape and more metal in the middle,  better flow perhaps because
of the channel shape.

I'll give you the whole thing when you come over.
