Thread: Successful gasoline to propane generator conversion

  1. #1

    Exclamation Successful gasoline to propane generator conversion

    So, last week I ordered the SEK - 4A and SEK - 5A propane conversion kits from Century Fuel Products.

    http://www.usgemini.com/Generator-Conversion-Kit.html

    $240 for everything.

    They arrived today, and after about a half an hour positioning everything and making up fittings, and another half hour or 45 minutes to install, and the generator is up and running on propane power.



    5000 watts of heaters and 250 watts of halogen light.



    The low pressure demand regulator. The large set screw with lock nut at the top is the demand needle valve. You manually set this for optimum run at peak load and then lock it in place. The empty set screw sockets on the top of the rail are for the gasoline tank, which is removable on this model. These two holes required drilling through the frame.



    This is not the best shot of this, if anybody is really curious, let me know and I'll take a better picture. What you are looking at is the "injector block", basically a circular jet ring, milled out of aluminum, that bolts directly ahead of the stock carb with extension studs.

    This was the only problem that I ran into, these extension studs were threaded metric and I needed 1/4" x 20. No worries, a few minutes with a tap and die had them ready to go.

    The low pressure gas from the demand regulator is fed in here. Important to note is that all of the stock gasoline carb equipment is still in place. I have the tank removed for ease of work and clarity, but all that has to happen is to bolt the tank back on and hook up the fuel line to run regular gas. All the original carb parts, choke and air filter stay in place and will function normally.



    Another view of the demand regulator. The kit came with black iron closed nipples, elbows and a brass ball valve to make a shut off connection at this point, but I connected the line from the tank regulator directly to the demand regulator to cut down on weight, connections that might leak and things to get hung up on. Since it was going directly to the portable tank with a shut off valve three feet away, I didn't see the need unless I hook it up to the low pressure feed line off my 100 gallon propane tank. I don't anticipate using that unless $#@! really hits the fan.

    So far, runs like a champ, and now I can store emergency generator fuel without having to worry about it going bad in three months like the gasoline will nowadays.

    I highly recommend this kit.

    Post in the thread if you have any questions, I'll try to answer them

    Nice!

    I remember checking out a friends old milk truck that was converted over. I don't remember all of what was involved but it seemed very simple. I think it was like you say, everything still there but it I'm thinking it had a copper line running the propane gas in through the top of the carburetor. I also sort of remember the back of the milk truck littered with empty propane tanks.


    Now that I think about it, it all seemed so simple a person could, how do I say it,,, MacGyver a system together for a car if you had too.

    Yes, you could just run a line straight down the air breather or intake manifold or carb and make it work, but it would be unsafe and waste a lot of fuel.

    The demand regulator is the key component in all of this.

    You the man. Thanks for sharing! Definitely looking into this.

    I had a buddy who's dad had a Corvair with a propane conversion back in the early 80's. Never got to ride in it or really check it out though.

    I did the math for a Jeep conversion (258) out here but the expected mpg and cost of propane doesn't add up. For an emergency/occasional generator it would make sense for us.

    I can't remember what it had for a gas peddle. With your generator I think you've got a valve there and it can be adjusted to run a pretty steady speed. With a vehicle it might be pretty hairy trying to throttle it like a Model A.

    Thanks!

    Yeah, I don't think as an economy move it would pay off, this is simply to get to the point where I do not have to store gas around the property anymore. That is next to impossible with the $#@! gas being foisted off on us and I'm not willing to hump back and forth to the nearest FBO and pay $7 or $8 bucks a gallon for 100LL avgas.

    I've got 6 relatively new #20 BBQ tanks and 100 gallons of propane for the house, and anywhere from 200 to 500 gallons of #2 diesel in the heating oil tanks that, in a pinch could be used in the new Jetta, and the other two vehicles both have huge internal gasoline tanks.

    One five gallon container of premium with Sta-Bil for the small 2 strokes/lawnmowers, and I'm set.

    The throttle is set and governed mechanically, that is what maintains 60 cycles.

    The fuel is increased or decreased by the demand placed on the vacuum regulator.

    Basically, as the engine sucks harder, it releases more propane.

    Safety bonus, if the engine stalls or dies in use, the demand regulator shuts the flow of gas off.

    The Conch Trains in Key West used propane, (since the 70s). Had a good set up and ran Jeep engines.
    Not sure on MPG. But Propane is drastically cheaper than Gasoline,, and it stores.

    Nice set up. Grats.
    Liberty is lost through complacency and a subservient mindset. When we accept or even welcome automobile checkpoints, random searches, mandatory identification cards, and paramilitary police in our streets, we have lost a vital part of our American heritage. America was born of protest, revolution, and mistrust of government. Subservient societies neither maintain nor deserve freedom for long.

    Thanks, that was the primary reason for doing this.

    I had been keeping and rotating a fairly large amount of gasoline and it's just an aching PITA anymore, it really is next to impossible with the $#@! that is being passed off for gas anymore and the last thing I needed was to find out I had nothing but a bunch of phase separated $#@! instead of fuel, when I needed it.

    Awesome! Now I'd like to see someone I know build one of these. (Run gasoline engine off used motor oil and water).

    I'll take a stab at it. Somehow the heat from the exhaust is supposed to start a plasma reaction that converts the water and hydrocarbons into a burnable gas. It's clear to my how this works in "bingo fuel" reactor where carbon electrodes separate the water into hydrogen and oxygen and combine with water to make a usable fuel. But I don't know who the GEET reactor gets started. That's why I was hoping you, with your mechanical know how, could figure it out. One of my summer projects will be to attempt to build one and see what happens.

    Hmmm.....could this all be as simple as an oil/water fire.

    Why would you do that? (Serious question.)
    * Enforce Border Security – America should be guarding her own borders and enforcing her own laws instead of policing the world and implementing UN mandates.

    * No Amnesty - The Obama Administration’s endorsement of so-called “Comprehensive Immigration Reform,” granting amnesty to millions of illegal immigrants, will only encourage more law-breaking.

    * Abolish the Welfare State – Taxpayers cannot continue to pay the high costs to sustain this powerful incentive for illegal immigration. As Milton Friedman famously said, you can’t have open borders and a welfare state.

    * End Birthright Citizenship – As long as illegal immigrants know their children born here will be granted U.S. citizenship, we’ll never be able to control our immigration problem.

    Some "off grid" posts made me want to bump this, but I never saw your question, so of course could not answer it.

    The primary reason above everything else:

    $#@! gasoline sold these days with ethanol additives goes bad in about 2 months of storage, now matter how much you try and treat it.

    When it does, it can cause major engine damage, especially to two stroke engines.

    Keeping liquid fuel, (the EPA mandated ULS diesel is almost as bad) handy and fresh is next to impossible anymore.

    As long as the tanks don't get wet and rust out or leak, propane never goes bad.

    Important fact from an off grid or "prepper" POV.

    That's exactly why I did that to my generator. I also have the added convenience of the 1000 gallon propane tank I'm using to run my furnace, water heater and dryer with. Now I will never have to worry about not having fuel to run my generator in the dead of winter. As long as I have fuel to run my furnace, I'll have electricity to run it as well.

    that oil/water fire concept would work well with two gear pumps to control feed rate that are locked 2.5:1 water/oil

    feed the water gear pump with pressure regulated water and a pin valve...
    have water flow through gear pump that puts out 2.5 units per rotation
    have water gear pump shaft drive oil gear pump shaft that puts out 1.0 units per rotation
    feed the oil gear pump via gravity tank
    then you're maintaining steady water/oil ratio that would be more reliable than two independent drips
