Greetings Paul,
I came across the attached article which may be of interest.
Kind regards
Aden (Perth)


Aden sent a bunch of pdf files totaling over 5 meg which
is too large to publish so I extracted some jpg's.
Note that Audi was able to gain only 8 to 10 % in fuel
consumption reduction but that including upping the
compression ratio by a point. Therefor without upping
the compression ratio of the rotary you won't see
nearly the improvement in fuel consumption.
Every little bit helps however. My question so far
unanswered is what happens to the NOX and how
is it reduced to meet EPA rules? As far as I know
and as I recall NOX is greatly increased when engines
are run lean.

-------------------------------
After rereading the article there is such a thing as a
NOx "accumulator" used what ever that is.
Bosch also claims up to 40% reduction in fuel
consumption. Obviously at light load. Should help in
the city cycle and maybe aircraft cruise power levels.
Interestingly enough the throttle is wide open in the
lean mode and the power is controlled by the amount
of fuel injected just like a diesel engine.
The RX8 engine already uses a fly by wire throttle.
