Where on earth can I find a PWD operated proportional (?) liquid valve. I see a ton of reference to such a valve but can find no direct reference to an actual product.. I've rambled around all the haunts and can find nothing. With such a designation.
I have a relatively simple project I'm working that would be very slick if I can make it work. I am installing h20/mthanol injection on a supercharged car. Ideally I would have complete control of the % of h20/meth to the air/fuel mixture.
This is usually done in a very imprecise manor. I happen to have a spare AIC (additional injector controller) It takes readings from all over the engine and in conjunction a user programmed "Map", calculates the precise PWM signals for the injector.
What I would like to do is drive a small proportional/ "pwm valve" for the water injection. I can find none. It would need to do no more than a $50 fuel injector. (& why wouldn't a fuel injector work...corrosion?)
So where are these PMW valves?
Thanks in advance
Not: the injectors run at 300 HZ to 15,000 HZ, my h20 injection works with 100psi at 12 v. Not sure of the fuel injector voltage input.
