He lobs over, looks at the installation, asks a few poi= nted=20 questions, and sees the problem almost immediately. Both Rocky &= I=20 ended up with very sore and very flat foreheads that night - (You kno= w=20 how you slap your forehead when someone points out the=20 blatantly obvious??) - not to mention very sheepish and embarrassed l= ooks=20 on out faces.

I have been pursuing an interesting project and truly hope you mi= ght=20 know someone that can give me the information that I need. I have been looki= ng=20 at the possibility of direct injection for the rotary. I've made serious=20 inquiries to Orbital which started on your side of the big pond, ( they have= a=20 USA division as well), and got some info which I needed. The Orbital system=20= is=20 in use on many 2 stroke high power apps. like Mercury outboards, Apprilla=20 scooters, and Sea-do watercraft. The system isn't a direct injection like a=20 diesel, it maxes out at 9 Bar. This system could solve several rotary proble= ms=20 though. 1. Fuel injection and metering away from the exhaust side of the eng= ine.=20 2. Better mixture control since the charge can be put in after the ports clo= se.=20 3. Fewer problems with charge "blow out" by exhaust overlap also because the= =20 ports are closed prior to injection. 4. Possible charge stratification to bu= rn=20 lean mixtures and improve BSFC. The system uses a system with 2 injectors pe= r=20 injection site. one is a conventional fuel injector from any source ND, Bosc= h,=20 GM, etc. The second and different injector is an air injector that is=20 pressurized to 9 bar and blows the fuel into the chamber. I NEED A ECU THAT=20= CAN=20 TRIGGER 2 INJECTION PULSES PER POWER STROKE IN CLOSE SUCCESSION WITH THE SEC= OND=20 EVENT (AIR) BEING TIMING CRITICAL. The other wrinkle is that I am going to b= e=20 running a 20B which means I'll need a minimum of 6 injector control pulses o= r 12=20 if I run two injectors per rotor. I was hoping you might know one of the Mot= ec=20 guys well enough to see if they might comment/bid on such a system? Here's=20 hoping. Lastly in a much later incarnation it might be possible to run the=20 engine on "fuel control" without throttle valves, (like a DI diesel) and imp= rove=20 efficiency further. The last is a pipedream at present, but the other=20 possibilities are real. Interestingly the needed air pump, which would come=20= from=20 a Mercury outboard has the oil injection pump for the 2 cycle built into it=20 which could be used for the tip seal lubrication (either 2 cycle or sump=20 oil)
