Butane Injection

[opofus]

Has anyone tinkered with Butane / Propane injection? I am interested in kits, or a parts list if available. Or...a complete how to guide.

You can do the same thing with hydrogen, and the fuel is cheaper.

Compressed hydrogen is cheaper than propane??

i like it! i wana do it! soon but i have alot of questions? anyone have answers? i havent heard much about this?

#1 in the link to that thread earlier, he mentioned running it to the airbox? i though propane was an intake horn kind of thing? #2 can this do any damage whatsoever to the engine, by running to much or something? #3 how will egt's react and how much real power do you see? especially on a truck running a lot of fuel? and #4 most important, but least worrisome... how explosive is this? can it ignite from only strait heat? or does it require a spark?

thanks
Derek

A friend of mine is running a Hydrogen generator on his '06 CTD. He picked up 2.5 MPG across the board even grossing 22,000lbs.

Distilled water is cheaper than propane.

i answered most of my own questions? but i still have a couple

can you run a setup that is fumigated into the intake all the time? wouldnt it cause the engine to idle high/runaway? because the way some of these guys talked about it was like it was a all the time kinda thing?

and still secondly is can you inject/fumigate too much? REALLY dont wana ruin something, so i gotta make sure? how safe is this really? i am interested in doing it, but honestly a little worried...

thanks,
Derek

Propane (and definitely hydrogen) start at a low pressure and need to be introduced before the turbo to draw it in under high load.

They can both do damage to the engine, but you have to be getting pretty crazy before you're risking it. The little kits that guys run to get better economy are pretty safe. Advanced timing at high boost and low RPM's are when you're most likely to see it cook off, just like preignition on a gasoline motor running too low of an octane. Without an ignition source, both fuels are less likely to cook off than Diesel fuel is, but they're also both gases and are therefore more likely to find an ignition source.

Propane and hydrogen both work on the same theory once they get to the cylinder, the only difference is that hydrogen has less energy per volume and requires you to cleverly circumvent the rules of the universe before you can see its benefits.

Say what?

i've seen hydrogen ignite in air at 50#s [in a refinery, pipe leak] makes a pretty good cutting torch. this one sprayed on the leg of a 300' column and brought it dowwwwwn., tc

back when I was a kid we used natural gas on our staionary diesels on the pipeline. It used the NG like a sparkplug to get a better burn on the diesel. Same thing with the hybrid hydrogen units they sell right now. You get a more complete burn of the diesel you are spraying in the cylinder.



Like it or not they do work.
