Thats what Im saying, our valve is both PWM and proportional working with different types of signals. SO if you want it to buzz like a bumble bee use the PWM frequency, if you want it proportional use the 0-5V signal. What ever floats your boat.

Lastly I understand your point about flow capability and pressure rating. We didn't just buy these valves off the shelf and wham they worked.

All we wanted to do was offer customers a different choice. Something that was faster than the pump version.

 

And I know a certain water injection company that tells everyone they own a patent on a safety device as well.

All I can say is that they (Clippard) are licensing the technology from someone else, they dont own the patent on anything.

Proportion valve is current driven or chopped DC (300Hz-500Hz). Fuel injector works between 30-65Hz.

With the best intention in the world and with however complex electronic control, a proportional valve cannot work the same way as the fuel injector.

Educate me please.

 

Since water mixing was not a concern to my setup, this is why I decided on the fuel injector A fuel injector does a damn good job of controlling things.

 

I meant to say that use the valve based on the fuel injector signal using hardware/software to convert the signal to something the valve understands, either opening to a certain position or PWM. Sorry for the confusion, but I certainly see your point.

what a liar

 

what are these mr coolingmist?

 

Mr Slow Car,

I will repeat for you one last time.

I have never purchased anything from Clippard or any distributor of clippard. Our valves are not in any way manufactured by clippard.

I cant say it any more clear than that.

Just because they look similar doesn't mean two manufacturers don't make an ALMOST identical product. To get around a patent, there isn't much you need to change to a design. trust me, the company I work for does that to competitors products everyday,lol.

Manufacturers can even sell their design to another company.

 

I believe the proportional valve - by defination, whoever makes it, should all behave the same.

Just to clarify , there are two types of inline solenoid valves:

1. PWM valve: control flow by ratio of open/close period (aerosol button) - used by aquamist.
2. Proportional valve: control flow by amount of lift over an opening (water tap)- used by coolingmist.

There is a significant difference on atomisation quality at low flow. Will be explained on the "indepth study..." in due course.

 

Hi guys!
I am back on the WI project...
I already have pump, injector, fuel pressure regulator and hose...
I should start calibrating this week end and install soon...
I will post some picts in the next few days with my experiments...
Cheers,

 

Best of luck! Keep us posted. Once warm weather arrives, my setup will get put to the test

 

Can't wait.

 

Hi Guys,
So I did some tests today and here are the results of this first approach:
My items:
-Bosch Fuel Pump
-FPR Aeromotive 1000-6
-Pressure gauge 0-100 PSI
-Fuel Injector from a Hyundai ATOS (the smallest I found!)
-Some hose...

The approach of the day was: Evaluating system future :-) and I have some good news...
1- Excepting a small leak on the circuit (my mistake!) everything works fine.
2-My Bosch pump with the FPR is giving me a final pressure from 20 to 56 PSI.
3-Injector is working fine!

I made some measurements and that's what I get:
It takes 3'40 min to fill a 600ml Coke @ 48 PSI :-)
So I can decuce that my injector size is 164 CC/min

Now the good new is that this injector is a "4points type shower" so I should be able to split flow /2 with some epoxy to get 82 CC/min and with a 30PSI FPR adjustment, it should give me what I need: 51.2 CC/min.
========================================
For all of you: With this item configuration, the system can be adjusted from 512CC/min Fuel injector size to 812CC/min just moving the FPR....
========================================
What's next???
-I want to calibrate my injector to 51.2 CC/min cause my goal is to mix 10% water vs Fuel and I run OEM fuel injector that are 512 CC/min.
-I will work this week on the electronic, my plan is to get the 4 fuel injectors signals thru some optos and pilot a transistor to manage the WI.
-I need to make more tests to check injector response time for final adjustments...
->I definitively want to inject a small amount of water on each fuel injector pulse to minimize condensation and help all cylinders to have their water :-)))
(I will publish the whole story and theories when this will be done!)
========================================
So this is what I have for you today but stay in touch, I'll be back soon with the next step...

All comments are welcome!

Cheers,
