I have searched the forums, and, while I found several posts that were similar, they weren't simple enough; typically, posters were looking for something close to this, but had a few extra functions. Any help would be greatly appreciated.
I am working on a project with a friend, and we need a more precise fuel delivery mechanism.
My initial thought was of trying to control a fuel injector somehow, with a potentiometer to control the amount of time the injector was open. Since injectors are typically only open for milliseconds at a time, I was thinking that a small solenoid might do a better job, as it will need to be open for somewhere between .5 and 2 seconds, and i would probably have to make the injector open a bunch of times to achieve that length of time. (Going to be trial and error to determine the exact time...) I was thinking (I know, I know... I probably shouldn't do that) that a small circuit to energize the solenoid based on what the pot was set to, would be ideal.
I have never designed a functioning circuit, though I wish I knew more about electronics so that I could. I have some fun ideas. I have built several circuits designed by other people, and have modified some of them to be more what I needed, so I am capable of building them... But design is way outside of my league at this point. I am a noob, so hopefully you'll go easy on me (I do have the basic fundamental understanding of what components do, and can read "more than basic" schematics, though)
I saw several posts about similar circuits using a 555 chip. Would I be able to vary the energize time using a pot with this chip? Or would a different route be easier?
Any ideas or schematics would be a huge help!
Thank you very much for your time.
