special V8 multifuel vehicle

" And this attitude is why there is almost no engine work being performed on this forum "

I think it is because of all the wild speculation. Plus the specter of EPA fines. Plus this is a damn litigious country I live in. I thought about a throttle interceptor for the prius, but with the cases of toyotas driving into houses and blaming throttle issues, I don't even know if I can share it without making myself or anyone else liable. And that itself doesn't even mess with emissions (though good luck explaining that to a bureaucrat).

So it is utter crap to point fingers.

And please forgive the overzealous denizens of this forum. Many are not scientists, and those who are have very narrow specialties as those of us in the sciences are wont to have. They easily get excited about pie tins and used sign boards and denigrate anyone who wants to do anything mind bending with engines. The few on this forum who do work with engine modifications have often come under duress from experts who have never set foot inside a dyno lab.

Feel free to stick around for a bit. Just ignore the "negative Nancy" crowd of experts and maybe you can get a constructive thread going.

And yes, I have built vapor carbs, GEETS and reformer engines. They all have their positives and their pitfalls. But, when you side step the hocus pocus surrounding them, they all have some good science.


rusty,
the only thing i dont agree with is the geet. i actually met paul, i spent about a week helping him move out of oklahoma, i gave him 300$ for designs, then spent about a grand on the right hoses and welded up a vehicle sized geet, when it didnt work paul wouldnt help, wouldnt refund, and i was pretty mad about that. i understand fully annotated engineering drawings, and paul gave me scribbles with measurements for my money then left me high and dry. i believe his little plasma vortex tube belongs in the unicorn coral.. just because its not what he claims it to be, but it is a vapor carb. i have seen it able to use heavy oils as fuel but with constant air adjustments needed and no intake or exhaust flow its not practical at all

Frank is right, my dad bought the fullsize bronco custom ordered from ford back in may 1989. it was the first vehicle i rode home from the hospital in, and i thought it was the coolest truck id ever seen growing up. theres no way ill ever get rid of it, and some will think i have destroyed it with my modifications. i bought an f350 in scramento and flew out to get it for next to nothing, drove the 460 4x4 5 speed f350 back on 7 cylinders across the country and rebuilt the parts into my bronco. i have military runflat tires that are cheap but heavy, the military 37's, and it is a beast to drive down the south canadian river, with the combo i can lay down rubber on dry pavement and it is the most fun ive ever had. absolutely abused it all till about 2 years ago and started fixing every single thing the RIGHT WAY. now its got everything rebuilt, i just need to drop in the stereo, and wire up everything, finish the rear bumper, and do the alternative fuel experiment and its ready to drive. i actually have made money buying a parts truck for near nothing, then selling the 351 and c6 and dana 44's & everything else i dont need. now if i could get it puffing some syngas (from hydrocarbon waste) for long range hi way cruising i would be in heaven, i could drive my favorite truck state to state, out to pizmo ect.. AND NOT SPEND A FORTUNE DOING IT

It's really screwing with my head that the vehicle you came home from the hospital in is a factor in your decision making. Did you imprint on the truck instead of your mom or something?!?


finally this book makes sense!

its ok, you dont have to understand, i just love that bronco. ill never get the money back ive spent on it, its ok. it can drive straight over a prius like its a speed bump. and thats why its so much fun.

its just something about taking the top off and driving through the woods, down the highway, hitting 4x4 and crawling though the mud or up to the top of a mountain and seeing for miles, through a river to the otherside, going places youve never been before, and even taking a camping trip to the lake or woods and instead of sleeping on the ground looking up at the stars with my girl, broncos are just great.

ive driven out to blue hole in arkansas, its amazing

ok, but you have to agree that it a purely emotional choice, it has nothing to do with efficiency. Science has basically "left the building" in that regard... Had you made the trip 2-up with a bed roll on a tt600 (in half the time) you might be making a different plea now.

[dustyfirewalker]

science hasnt left the building, theres reasons to choose a big engine when you know your killing some power for the multifuel ability, im not going for ultimate mpgs, just going for reducing operating costs. if it gets horrible mileage, but i pour something i got for free into the tank i think thats ok. i guestimate based on what ive seen before i will dead reckon with 10-13 mpg highway without pulling my relatively light weight jetboat to the lake or towing anything else. but like i said if i can get a few shops close to mine who pay to get rid of their oil to give it to me, or a veggie oil connect, or a machine shops waste solvent (about the consistency of diesel) with enough of that it will be fine. i actually drove to dallas down i35 and had a 1/4 tank to drive in dallas before leaving OU/TX and filling up for the trip back. if i could do that again and just pay for starting up and shutting down on gasoline, and maybe throw 10-25% gas in the tank. thats a huge fuel savings in my mind. (that was driving with a 460 to dallas in my truck pretty much exactly the way it is now)


also i do have an xr 250, xr400, ktm525 dual sport, yzf600r, i regularly ride them all, i love motorcycles, and love picking my lines up a mountain pass or through a creek on a hot day. riding in the mountains is the best way to become a better rider. but i still like my truck, and i can even throw 2 bikes in the back of the bronco if i want. thats the reason i want a pick up for dialy driving, i go pick up parts, and do work out of it alot. i need to be able to throw a bunch of tools/crap in the back. and the big vehicles are whats eating the most gas, so im shooting to reduce that

[P-hack]

I'm still not clear what you want to do though, you talked about using pvc and roadkill for fuel (I'm assuming cowpies aren't off limits either), which makes sense, kinda, with a gassifier type of arrangement, but now you are talking about pouring stuff in your truck.

Early on you mentioned ease of use and operation, but of course the more you have to refuel the large vehicle, the more work, which also seems something of a contradiction.

[dustyfirewalker]

i was refering to a woodgas set up, where beleive it or not you can throw anything but rocks glass metal in and it will burn into syngas that fuels the engine, and all your left with is ash,

its large, and bulky. the reason (ill say it again) is because of larger engines, and because wood has relatively low energy content to gasoline, wayne said 16lbs wood= a gallon of gas or something close to that, so what my "idea" is use hydrocarbons that have lots of potential energy instead of something with less energy. this means i dont need 55gal drums, i just need something just large enough to heat waste oils or other flammables up to a temperature that the will "crack" or partially oxidize, or smoke. this is what will produce syngas,

so if i do it right, by the time these oils poured into my fuel tank, then sent to a carb, then heated, then atomized+mixed with hot air+steam, then heated further, then get into the cylinder, they will burn. and make the engine do what it is supposed to do run. without smoke

others have just poured it in the tank and ran plasma ignition like you saw in the videos, they get smoky exhaust, the oil wasnt hot enough or vaporized enough to burn cleanly, i dont want that, but if its minimal i might just deal with it. i will do anything i can to make it appear as if its normal exhaust with out using a catalytic converter.

others have heated the oils up with a heat exchanger and it didnt smoke marcello has run a generator with waste motor oil and small amount of gas when warm and he just runs his intake charge past the exhaust pipe! just getting it hot enough and no smoke! nothing else and he got a spark engine running on waste oils cleanly, and he shows diesel, veggie oil, wmo, atf it all works. now i want that for my truck and im building something similar.

so im going to heat them up, add steam for smooth combustion and making sure detonation doesnt occur, and start up and shut down on something that will easily start the engine. thats the plan. it might change if i have a lot of tailpipe smoke, i might add things to fix that. but my goal is to get an engine thats happy burning a WIDE VARIETY of liquids i pour in the tank. i believe with a gas engine i will have a greater variety than a diesel. IP's and injectors for diesels are expensive. a quadrajet is way cheaper. ive thought about this along time, and im so close to having it ready to test.

if you get oil hot enough, or gasoline, or ethanol, ANYTHING

you get smoke

https://www.youtube.com/watch?v=qqzJzcjNr6c

that smoke will run your spark engine, and no smoke will exit the tailpipe.

same thing as woodgas, just different fuel, you get to pour what ever oil/hydrocarbon/alcohol into your fuel tank and run it if you build it right.

and quite often around the point it smokes, if oxygen is present it could ignite, marcello shows it didnt effect the engine, but i still want to use flame arrestors so when it happens in my carb spacer it will be stopped by a certain point, and wont reach the carb either.

The difference between 10 and 35 mpg is pretty huge, especially after a few months of the miles adding up. Plus, if you got a beater car, you could experiment to your heart's desire and not worry a whole lot about destroying it. Once you find something that works, then put it to work on the Bronco.

This video is pretty interesting. I also find it amusing that he lets the flames touch the fan and his wall. Does he want his house to catch fire??

So the basic theory here is, get a second fuel cell, heat it with engine exhaust, run the vapors/fumes into the carb and then shut the gasoline supply off? How are the vapors regulated? If you are idling, will too much vapor build up? How do the vapors keep up at wide open throttle on that tiny, fuel sipping 460?

[P-hack]

ok, so you may have glossed over this, but how do you heat the oil?

Do you appreciate that I'm not attacking you personally, just that as-delivered there are many gaps in your proposal that someone who isn't you is going to wonder how long you have been doing all your emissions testing with your nose?
