Nu-uhhhhh....you can say "can't". Hehehehe
Uhhh...I found that little mesh you're talking about when I accidentally
ran over one of my factory injectors. (Pretty cool lookin in there.)

Subject: DML: Re: Fuel Injectors
I was going to say "You can't just take them off and clean them yourself
- send them off..." but it was then that I realized I had used the word
"can't". Since that word doesn't compute w/some of us - lets discuss
this further.
Professionals take them off and clean them - why can't we? I have
studied (few mins) a couple that I've held in my hand. I understand
that they have a filter "basket" in the top (fuel entering) section.
This filter basket is normally replaced (along w/o-rings), the injectors
flowed for a baseline, then cleaned, then flowed and cleaned until
within a certain tolerance of each other. Ones that don't flow like the
majority are replaced. Sounds simple enough.
I looked for this fileter "basket" and didn't see anything but possibly
a very small hard (possibly metal) o-ring looking thing sunk flush into
the top of the injector. I assume this is the filter basket w/only the
top rim exposed. Looking down into the fuel entry hole w/a flashlight
confirmed that possibly a thin metal mesh is just below. How you get
that sucker out
- I dunno.
Next is cleaning. A pressurized (around 50psi) fuel/solvent source is
needed along w/a jig to hold the injector upright (and seal the
pressurized fuel/solvent). The bottom will need to be partially
submerged below the rim of (or at least pointed at and close by) a
container to catch the outgoing fuel. Preferable a cylinder w/graduated
marks for measuring output volume for a given time.
That brings us to how to "flow" them. You will need to supply a voltage
on one pin (continuously I think) and then use the gnd circuit as your
trigger. Firing the injectors for a fixed time period will serve for
comparison purposes. There is no real need to be as precise as a number
of milliseconds provided that your total period of "on-time" is
consistent.
Fuel injectors come in either high-impedence or low-impedence designs.
There are "saturated" and "peak-and-hold" types of drivers for the
corresponding design (can't remember which goes w/which). I'm not sure
if you absolutely REQUIRE these drivers to do something like flow them.
It is true that to get the proper characteristics out of them you need
the appropriate driver - but just to flow them for a few seconds? I
dunno. Anybody know? The drivers are readily available if need be.
Hell - Bernd is probably working on some as we speak 8)
Comments?
