Does anyone know how the apex seal on the Wankel engine is lubricated? Is oil added to the fuel or injected at some point on the perimeter or is it not lubricated at all?

Thanks for pointing out these engine sites. They make very interesting reading. I was aware of these type problems in aircraft applications but these articles point out just how common and severe they can be.
I guess my point is that the statement by Herschel Smith makes it sound as...

I don't understand the bit about this engine having "inherent dynamic imbalance". Since all cylinders are in the same plane and opposite pistons have equal and opposite accelerations, this engine should be in perfect dynamic balance.

Thanks Terry,
I had suspected it was something like what you say. I wonder if the play in the linkage was due to inaccuracies in machining the cam back in those days. Today, with CNC machining, it would a snap.
May I ask from where you got your information.
Fairchild built and tested a number of Caminez engines, see ( www.prototype-design.com/images/caminez.jpg ) back in the 1920's. A few were even flown in planes. Does anyone know exactly why this engine did not make it into production? I suspect it was due to failure at the cam to roller-follower...
Just answering my own question. I recently came across a very good discussion of wankel port timing including typical values for various states of tune. Go to http://personal.riverusers.com/~yawpower/dectech.html
Does anyone know what the typical port timings (inlet & exhaust) are for a Wankel rotary like the Mazda RX engine? I assume that with respect to top and bottem dead center, they are similar to a reciprocaters' poppet valve timings but slightly different to allow for the fact that ports normally...
