Yeah, I was just going to cool the LP to get it at a temperature and pressure where a standard fuel injector could handle it.
It's counter-productive though. One thing I've learned in studying this, ideally, you want to direct a stream of liquid LP right at the intake valve so as to get as much ...

Re: Source for LP GAS injectors

so how do you buy them? pricing

Looks like the real deal. I'd be interested in getting some info on those Kiehin injectors as well.

Off subject a bit..
I've been thinking about an experiment (not a practical idea for a regular driver), but just to see if it works....
Propane is at 55 PSI when it ...

All you need is to make sure the fuel doesn't start to vaporize. Only a slight increase in pressure is needed over that in the tank, as long as you regulate the heat input into the fuel system. The system ends up being very similar to a gasoline system, i.e., pump, bypass regulator (of sorts ...

Since the LPG is being stored in a state of equilibrium, as soon as you lower the pressure only slightly, it will being to vaporize.
It's critical that the LPG is in a complete liquid state as it is injected.
And for it to be a liquid at 10 Bar at Standard Temperature Pressure, the fuel would have ...

I found the owner of BDE, Ltd. (now closed and the rights to the liquid injectors sold) today. I spoke with him on the phone this evening.
BDE provided the injectors for the vehicle in the Ketterling paper (the link is posted earlier in this thread by miked).
They are true liquid (16 BAR) injectors ...

Couldn't get link to work...

Anyway, may sound crazy, but here's the diesel injector type I was referring to - eBay ads NOT allowed on these forums/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7950329526&category=46098
These will get cheaper as the "new" wears off.
Now to find some tech information.
I'm assuming super low Z ...

Ain't nothin' easy, is it? :?
I'm having trouble locating the Yahoo user group foto page you mentioned. Haven't learned my way around well yet.

So by my calculations, we're talking almost $200 USD per injector. Pretty pricey, huh?
That eats into the fuel cost savings aspect pretty heavily, and would only leave me with the glory of having something unique.
I'm confident that I can design and build all the peripherals (with the exception of ...

Great..........

I never expected to run across anything on liquid propane injection here.
There isn't a great deal of information available. This Vialle is the first bonafide company I've found that manufactures 15 Bar injectors. I checked out their website and noticed dealers in the Netherlands and Belgium. I also ...
