Can the manifold connection to the block be reversed -

Will

it

fit such

that the exit pipe points toward to front cover rather than

the

flywheel?

Just thinking about future projects.  Looking forward to seeing you

and

Robin again at Sun & Fun

Ed Anderson

Thanks Ed we will be there. This year I have volunteered so I will be

spending

a lot of time in the engine work shop tent in the afternoons.
Robin wants to head out and fly the 182 back on Wednesday but I might

just

put her

on a UAL jet and send her home :-)>

Great! will see you there.  Should get a lot of attendance after your
article on the rotary in SA.  I was invited and gave a talk to the local

EAA

chapter about the rotary engine - had a fair turnout of about 30 folks -
lots of questions and several mentioned reading your article and

commented

on it favorably.

Ed, as I recall you built a fuel injector test rig. Am I wrong?

Paul Lamar

In a manner of speaking, yes.  I have a injection trigger device/timer which
provides different pulse widths and rates.  Hook it up to a 12 volt battery
and plug a socket on your injector and you can hear it "click".  I also took
an old fuel pump and hooked it up to a Mazda injector rail.  I plug the
injectors in backwards first, fire up the pump to get 40 psi and then
trigger the injectors which of course causes the cleaning fluid to flow
backwards through the injector cleaning out the injector screen basket.  I
then put the injectors in correctly and flow the fluid through them into a
plastic beaker (much taller and bigger than I really need for this, but it
was graduated in CCs.

For safety reasons, I do not use gasoline, but one of the injector cleaning
fluid, its has much more viscoity than gasoline so I don't bother trying to
check the flow rate, I just check that all the injectors I am using flow the
same amount.

I'll post a photograph of the rig, but it uses a pump, pressure regulator,
fuel rail, recovery tank and the beaker (And the J C Whitney injector
trigger mentioned earlier).  It certainly detects injectors with major
defects like - stuck shut or stuck open or seriously reduced flow.  I can
tell you using 16 year old injectors at the continous high rate that we do,
you will find a large percentage bad - or at least I did.  I had a couple of
mysterious malfunctions that were eventually traced to malfunctioning fuel
injectors.  Anybody planning on using NO2 will certainly want tested
injectors.
