Dave, Whats not to like?
BTW If you stop drooling long enough you will notice in the text that they have changed the STROKE (e-shaft offset) AND widened the rotor housings. This will be an all new engine. That doesn't mean that the 13B can't be improved using these technologies though. I have been promoting DI for the rotary for some time. Of course with the desire to go back to carbs on the other list it has mainly fallen on deaf ears. To some extent using the old style mechanical injection I can understand the reluctance. The new common-rail piezo injector systems are another matter though. You should be able to improve the efficiency and power. I'm glad that Mazda thinks so too! No longer a voice in the wilderness. OH yea, the fact that the fuel is being injected far from the exhaust manifold isn't a bad thing either! At least in our aircraft applications.

I LIKE it... I like it a LOT.

I wonder if the increased displacement is from thicker rotors, or
increased lateral dimensions...

Thicker means easier adaptation in my mind for existing PSRU's.. if the
bolt pattern remains the same. The mounting plates would need to be
remachined...

I'm all about lighter, and I LOVE the idea of direct injection - no
throttle lag, minimal wasted fuel - however single injector per rotor
looks like the name of the game here.

So.. have an engine that makes MORE power than a 13B yet weighs less and
is in theory more efficient.

Looks like a nice upgrade in the future..
