Isn't there a law of motor performance that says that two motors putting
out the same horsepower are consuming the same amount of air&fuel, assuming
efficiency differences were not significant?
I'm guessing that the problem is with that last
assumption. I bet we're operating at an efficiency level that's
unimaginable to the folks at Lycoming.
I still like
the Ellison, and think that anyone who doesn't believe it's an injector, should
set one up one day. Step one is to purge the air from the system.
You do this by blowing air at the venturi with the fuel pump on. The
shower of fuel that comes from that absolutely has to be seen to be
believed! I would seriously consider using one on the single rotor, since
one would be plenty. In all of this Ellison discussion, someone
already pointed out that they don't recommend running auto fuel in them. I
think lots of people do, but the fuel you buy can change additives from one tank
to the next, and the next one you get might be the one that melts the
diaphragm.
Example- I
restored a 65 Corvette years ago, and had a Holley double pumper carb. I
had a T fitting that split the fuel supply to go to both bowls. This
fitting happened to be plastic, and worked fine for as long as I owned the
car. Eventually, I sold it, and build an AC Cobra replica, also with a
Holley double pumper, and the same T fitting. I drove this for a year or
so, then one day smelled fuel, and opened the hood to see fuel spraying out of
that fitting. The station I always bought gas from had a big sign out
front advertising some new wizbang additive, which apparently attacked the
plastic. Rest assured that I immediately made a frantic call to
the guy who bought my Corvette.
Just wanted
to give everyone something else to worry about :-)
