Tracy,
Sorry to beat this to death but I am a little dense......If injectors fire on the intake cycle
of their respective rotor and are not batch fired and the intake cycles of the rotors are
phased 180 degrees of the eccentric shaft apart how do you avoid pulseing the injectors
every 180 degrees (twice per eccentric shaft rotation) ??

Yes, Ed has it correct. I would add that the injection is not batch fired but is port, i.e., the injection pulse is timed to coincide with the intake stroke of the rotor it is feeding.

Dean,
Here's my take on it. For all six faces to go through their cycle requires
1080 deg of e shaft rotation. So if you have six faces (3 x 2 rotors) then
each face requires 1080/6 = 180 degrees of e shaft rotation to complete its
cycle. So two faces (one on each rotor) would complete their cycle (intake,
compression, combustion, exhaust) in 360 deg of the e shaft rotation.
I believe the EC2 fires all four injectors (assuming it has staged) once
during that 360 deg rotation of the e eshaft providing sufficient fuel for
the two faces (approx 2 x 40 cid = 80 cid) of ingested air/fuel mixture.
But, Tracy is obviously the one who really knows {:>)
