project dual-fuel is a go
#23
the guy at restless wheels (in manassas) said that all propane is stored and used at the same pressure. so i do believe you can get it filled at any propane filling station. also, if you get a 20# tank (bbq grill style), you can swap them out at your local 7-11. be careful, because blue rhino uses a proprietary filling system on most tanks.

you should convert it to run off ethanol, then just get. A license to distill your own non-drinkable moonshine.
You really only need to make your truck run 30% richer via larger injectors or trick the efi.

Go IAN! hahaha. Very interesting, I hope it works out just as you'd like it to! BTW, in your platform in the rear that you're building, ......could you make spots for emergency tanks?

did some more research today, found lng kits. much cheaper fuel, slightly cheaper conversion kit, but no filling stations reasonably close. and i'm not sure if i could run dual-fuel
#34
^^ thanks
just thought about it for a bit: most kits available are for carb'd engines. they stopped making carb'd engines ~20ish years ago. i put 2 and 2 together and would venture to say that there would be no side-effects to older motors. and propane burns a heck of a lot cleaner than gas, so less grit and wear.
if i can ever get a hold of them, i will ask though

i work with propane powered engine all the time at work but its all in equipment not on road vehicles, although some of them are ford 4 cyl 1.4L engines. I honestly don't think your going to see much benefit going to LPG. LPG is high octane, witch is great if your running a high compression motor as you don't have to be worried about pre-ignition.. also LPG is less dense than gasoline means per gallon you will use MORE than on gasoline. there is more btu's in a gallon of gasoline than a gallon of LPG. A gallon of gasoline produces 125,000 BTUs of energy and a gallon of propane produces 91,000. So propane would need to be 30 percent cheaper than gasoline to make the operating costs equal. the biggest advantage is depending on where you live you may be able to get tax incentives for running LPG as opposed to gas because of less emissions. also LPG burns much cleaner leading to less carbon deposits in your motor and the ability to run increased oil change duration.

ezrider- thanks for the input. as i stated before, it's mainly proof-of-concept, extended range, and slightly lower cost. i really want to step away from gasoline alltogether, seeing as how the middle east controls our gas prices. it would be awesome if i could get/make a kit for use with any type of fuel. but until that day arives, i'll start with propane (and propane accessories)

i like the idea of getting away from gasoline as well. however all the same influences on gasoline are on lpg, if you really want to explore alternate fuels diesel engines are really the way to go. even though sources of used vegetable oil to make bio out of are largely dryed up and most places want to charge a arm and a leg for there used oil where they used to pay you to get rid of it for them. diesel engines can be run off just about any type of oil if its properly processed. atf, motor oil, kerosene vegetable oil,soybean oil, canola oil hydrolic oil ect ect. (not recommended on a lot newer diesel engines as fuel systems and injectors are a lot easier damaged.) id love to some day put a 4cyl cumming in my ole yota, or maybe some sort of engine from a tractor. i bet one could see 50mpg with the right combo in a small yota pickup.

I'm a little suprised that there are more BTU's in gas than LPG. My only experiance was on the farm my dad converted a John 4010 from gas(I think) to LPG. After the conversion the exhaust temperature increased greatly. You could see him in the feild at night, the exhaust pipe sticking out of the hood would be glowing cherry red.
