The fuel rail would just have to be rotated 180 also and that would make the change pretty simple. Not easy, simple! If it turns out to be ugly, you could always paint it some other color than red! :>) Bill B -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Ernest Christley Sent: Friday, August 05, 2011 1:19 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Ideas for direct injection Jeff Whaley wrote: > Ernest, not that I'm a genius but the only way you might be able to do > a) is to supply the chamber with compressed air at low psi . but I doubt > if the spark plug holes and rotor face will align with the area under > the oil injector bosses. > > Jeff > > The alignment is really good, actually. I've attached a picture of the completed manifold. Those shiny spots right above the injectors are the oil injector bosses. Looking at this picture has me thinking of a different modification...turning the fuel rail 90*, and drilling the upright part of the support. That would direct the injectors into the outer runners at about a 30* angle. OTOH, I do have one of those self-contained HVLP sprayers that could give a me a good supply of air into the chamber.
