Hi, I've read a few topics here relative to propane conversion and I was surprised to find out that it seemed obvious that EFI engines could not run on propane. I don't know too much about the subject but what I know for sure, is that there is one company that offers propane conversion kits for EFI engines. (Got to www.poweredbypropane.net to find out...).
Perhaps, I know that these kits are expansive (around 1000$ w/o the tanks) because they are all electronically controlled and tuned. And the kit comes with a complete set of independent propane injectors (so you have to drill and tap holes in your intake manifold to fit them), and (that's what I find the most interesting), the kit is installed with selenoid operated valves that enables a switch from gasoline to propane and vice-versa with the flick of a switch. (the original gasoline system all remain intact). In fact, the engine is started on gasoline and only switched to propane when it has reached an its optimal operating temperature.
Also, they say that there is no power loss or drop in mileage when operating on propane because of the higher octane rating of propane compared to gasoline (even if propane has a lower calorific value than gasoline...)
Okay, that sounds pretty cool but you have to keep in mind (I do!) that all these informations are sypplied by the company itself... So, I would be pretty interested to share any informations about this technology especially if someone knows somebody who tried this system.
Finally, I don't want to start a hole debate on it but I'm suprised to see people saying that running on propane is not an economy compared to running on gasoline. As far as I am concerned, I already heard a couple of stories about some (carbed) vehicules being converted and having a considerable economy (but a power and mileage loss...the economy was made because of the price of propane and not because of the mileage...). Also, all those stories were concerning people that use to make lots of highway mileage. And finally, these conversions were made with old systems on carbed vehicules (it has nothing to do with the system I've described above).
I can't wait to see if people experienced the new system (the one sold on poweredbypropane.net...)
Thanks
