Is fuel injection compatible with LPG?

I'm thinking of doing some experimenting with completely electronic
controls - even the valves - and while I'm at it, going propane for long
life.

Can't do fully electronic control with a carb, though, so I'm wondering if
FI is compatible with LPG.

Unless I'm wrong about the need for FI - maybe electronic control of the
valves could be the equivalent?

Thanks for your answers!

This is hardly an answer to your question but here are some more questions
since you have me think about it:


A standard bug is not known for horsepower, so won't LPG make it much worse?

Doesn't LPG burn totally different? With the bug counting on a specific
combustion efficiency for optimal cooling, I wonder if LPG would need quite
a bit of adaptation in the cooling as well.

Woudn't the heads need to change? The valves probably need to be harder,
right?


Interesting pondering, though. Wonder if anyone's ever done that one
before..

You are starting with the wrong engine.

I've often wondered about this. It would seem that LPG at the right
pressure should work just the same as gasoline. I just really have no
idea what the right pressure would be.

Why would you need "fully elect control"?

I have a 1 cylinder 4 stroke engine sitting about 3 feet
from me. Carburated. Still able to run on gasoline too.
Has pressure regulator connected directly into the
carburator, and runs great off propane.

A neighbor has a 70's ford truck that is propane powered

they don't spit out smoke for sure

LPG makes less HP, making less heat. More heat, more power.

It can probably be done... Don't know the answer as to "how", but I know
that at least as far back as the '60s, the VW factory Quality Control tested
the engines using LP gas.
Good luck! BTW if you ever figure this one out, let us know or post it
on a site.
