Why MAT corrections can be so important. At least for the T/C, S/C cars. It would appear that WI would even be good for a N/A, since even in boost the MAT dropped to lower then what it was during cruise conditions.

The second log is with.
The results absolutely speak for themselves.

At the end of the WI on run something was going on, I have several items to check, but up to 95 things were much better.

What WI system are you running?

 

where is the water injected into?

 

Slightly reworked SMC.

 

Just in front of the throttle body.

 

I see a 140 deg difference there! Is that JUST water injection or did you turn off the 7th injector? If that's all water injection than congrats, looks like it's working really well.

 

7th injector wasn't used in either test.

That's been today's project. Somehow I wound up with a connector for it with two pink/black wires, for the 7th injector. So I had to peel open the harness to track it down. Yes, my pretty all new hand made EFI harness had an error in it............
I found the wire, now to reassemble things as well as they were.

Oh well, it's raining now, so I have something to do.

Oh, I also hope to repeat this with and without test with the 7th injector, and then again with/without propane.

 

Propane!!! Are you doing that for $/mile or just more testing?
I did notice a little turbo lag and then there was the wideband dropping in and out.... .

 

SMC? Details? Pics?? Website?

I've been looking at WI on my NA cars, actually. Was even looking at setting up a PWM output off the ECM (EGR maybe?) to drive a pump.

Pretty funny that you brought this up; I've been looking around for info and ran across this WI forum.. http://waterinjection.info/phpBB2/index.php

 

Where'd you notice the lag?. Or are you looking at the converter's characteristics?.

Propane in part guarantees a min AFR through out the combustion chamber. Or tailgating at cruiseins.

Maybe the PWM to run a solid state switching devise, I hope you don't mean running a pump directly off of the ecm.

Seems like a really effective setup would be setup to factor in several items. TPS, MAT, MAP, RPM, or something like that. Maybe a 555 as a ref pulse generator to a 749 and use that for running an injector for the Alky/water injection. The 555 sets the speed for the PWM, and then the VE table for the width of the pulses.

 

That makes sence .

 

I was thinking more along the lines of a windshield washer pump; nothing heavy duty. Use the ECM's output to vary the speed of the pump (and thus the output from the nozzle) with PWM. If that's not effective then use a full-size fuel pump and feed it with some solid-state stuff in between. I would think the ECM could easily handle a windshield washer pump though? At least this way you'd already have TPS/MAT/RPM/MAP to use to modify things, just some assembly code to work out. I suggested the EGR output because as I understand it, it can be made PWM, and the water cuts down on the NOx emissions anyway, which is what the EGR is for. Seemed like a logical switch!

In my searches on the 'net, I saw where they said a normal fuel injector would rust up pretty quick trying to use water, so I blew that idea off. Maybe not so with water/alky?

 

One of the tricks is to mist the water. You can't mist the water at 10-30 PSI, it takes pressure and a small nozzle. On the pulling tractor we run a Ford Start Motor to spin an agricultural spray pump, and the motor runs on 24v, and makes 200+ PSI. When you test fire the WI for it, it generates a cloud of water vapor. You want to generate SMALL droplets of water so that a) it absorbs heat instantly, and b) disassociates quickly in the first phase of it's reaction in the chamber.

All the guts of injectors that I've seen have been stainless steel.

Alky isn't that expensive, and has alot less surface tension to break to form small droplets, easier.

 

What kind of PSI are you running in your current setup? I'm seeing this Shurflo 100PSI pump being the most common - but will injectors withstand that kind of pressure..? (Obviously it'd have to be TPI injectors, not TBI.)

 

Heh, nice numbers… I take it that you're just spraying a set amount of water (turn on and spray, no real metering relative to what the engine is doing)? What is your trigger? How much water (gallons/hr, or maybe a really useful number like as a percentage of your fuel delivery or per hp or something)?

 

Yes, the SMC kit just uses a *jet*, and a variable pump speed adjustment. I turn it on at 4-5 PSI. You can use upwards of half the fuel comsumption with water.

The next setup is going to have some feedback and cut the BPC when the water is on. And will be using an injector, running the same PW as the fuel injectors. Lots of tinkering on getting Phase II correct.

 

Why not run it right off the injector driver? Ricardo and a few others suggest that the optimum water delivery rate will be a ratio to fuel delivery, so just pulse it off of the injector circuit and trigger the turn on from a map or mat threshold… You could even use a GN boost light sensor or a hobbs switch to turn the thing on and off.

I plan on doing something like that, but I plan on injecting the water much closer to the valve… I don't really care about manifold cooling but much more about it's effect in the chamber.

BPC?

So any idea what your actual flow rate was? Nozzle size/pressure across it? You've got nice data log numbers but they don't mean anything unless you've got an idea of what your delivery rate was.

 

This is just a WIP, I found a relatively cheap used setup, and just plugged it in to see IF there were any gains to be found. Now that I know what to expect, I can continue.

I have a 7th injector fuel injector that'll work fine for WI, and it has the suppport electronics with it.

No, the numbers tell the story the actual flow isn't as important as finding out of the concept works, and the rest will be tuning to get the engine running it's best. I don't care if it's a gal a min or gal an hour so long as I have enough tank storage capacity.

BPC= Base Pulse Constant.

 

grumpy this is all very interesting. on the propane that helping the detonation situation any ? im cursious to knwo becuase pump fuel sucks and id really like to put the screw to my car. also the logs for the WI look really promising. any idea on the air vloume displacement trade offs ? im wondering if putting a MAF in front of the turbo to measure airflow and see if there is a signficant enough drop on VE to warrant not using water injection. Ive always heard varying thoerys on the subject.

 

Ain't said nuttin about propane yet.

Water/Alky is used as a fuel replacement, there's no real change in the liquid volume in the air stream, hence the BPC correction.

Oh, you mean adding a MAF for data logging?. Ugh, something like the enclosed pic?. You mean like using a 8253 ecm and data logging that to record the air flow?, nope hadn't thought of that.

 

i should have known lol. ive been thinking about doing that with my honda to check on airflow etc. Hows that arrangement work out ?

im confused man. youve got DIS and the COP on there whats up with that ?

 

Still hammering on a few other lil projects, but I've had it working on the bench.

I had a long crank start problem. Turns out the non-EST part of the ignition module was dead. In diagnosing things, I had taken the DIS wiring off. But, while it was off, sorted out the bits for running a Quaick Start set of crank shutters. So now working on an Ultra Ingition system.

 

And don't even ask about the dual plugs per cylinder stuff, Doc would just go nuts. .
