Anyone know info about propane injection in a gas engine.

I know it can be done for deisel engines but like to know if it can be done for a gas engine. (I know the compression is higher for propane.)

thanks
Greg

I have a computer and hand controller from development prototype system developed here.
I am trying to decide if I use it on my truck or my LTD.
It can definitely be done.
What were you wanting to know?

 

Yes, you can run propane on a gas engine. My cousin just converted his cheby 350 to propane last month. I'm not sure if you NEED higher compression for propane, but his was already a high compression engine before he converted.

On average, I'm told you lose about 10% of your horse power, though. We also found out that not everyone can fill the tanks (he uses forklift tanks). It kinda stinks too.

No-- wanted to know if you can use propane injected in with pump gas.

thanks

 

Sorry. Misunderstood.

I suppose you could. Don't know what you'd gain or how you'd regulate it, though. You could set it up like a Nitrous system.

Just out of curiosity, why would someone do that?

Propane is for diesel trucks it works just like NOS for Gas if you put Propane in a gas motor kiss it and you goodbye. Propane will explode when the spark hits it diesels work on compression of the cylinders not spark.

 

That's funny.

Of course the propane will explode when the spark hits it. So does gas. That's kinda the idea behind internal combustion engines, isn't it?

LP is actually less flamable than gasoline and needs more oxygen to burn than gas does. Making it almost SAFER to run than gas.

I guess Kevin doesn't understand internal combustion engines go ahead and hook up propane to your gas motor just do me a favor and video tape it cause I would love to see the motor come apart. what your looking for is the O2 in nos not the explosion "simple chemistry". with propane your going to get an uncontrollable explosion. Yes propane is more stable than gas unless it is under pressure i.e. in a cylinder wall with a piston pushing it and a spark from the plug. NOS is safe and cheap if your looking for the kick read the instuctions and don't go wild a fifty shot will give most truck guys what they are looking for and requires little to no engine mods you could even get into the 100 to 150 range fairly cheap and easy. save yourself sometime and money and leave the propane for the diesel guys.

 

Are you saying that NO gas motor can run propane as it's primary fuel source? Or are you only talking about as a secondary boost source?

Kevin K.

 

I would be willing to bet that adding propane to a motor running on gas will simply choke it out due to to rich of a fuel mixture.
As a simple test why not fire up a lawnmower, run a hose from a propane tank to the carb turn it on and see what happens.
I have squirted propane from a torch (no flame) into an idling motor only to have it die.
The motor 'sees' to much fuel and chokes out.

 

Greg,

Here is an old post from another message board. It's kinda old, but it might be a lead.

Propane Injection

Check these guys out, too.

However, since I don't "understand internal combustion engines", these guys must not either.

Hope this helps.

Thanks kjkozak2, and all,

I checked out the sites a little-- looks very interesting.

They are still in discussion and I like the added octane posibilities and the cooling to
help with slight pinging.

I have been running propane on my '87 F150 - 300 Cu in six 4spd std for over three years withour a hiccup. It is "Dual Fuel" gas propane and I change seamlessly between gas & propane. Up here i BC (Canada) propane is about half the price of gas. My oil is still clean after 3,000 milesso I go 6,000 miles between changes. I just put my '95 F250 - 460 5 speed on propane and it too runs like a champ.

 

Wolfd,

Do you notice any decrease in performance when on propane? They say 5-10%, but I don't think I would be able tell the difference. What about compression? Did you have to increase it at all or are your engines stock?

Also, do you have hot water coming from the radiator to cool the regulator?

I'd like to fully convert my 460 because of the cost of gas and the steep angles I drive when off-roading. Don't want to have to rebuilt the engine to do it though.

Thanks!
