SVO diesel
    #2876850 - 07/10/04 11:59 PM (12 years, 10 months ago)

i learned something interesting a few days ago.you can run a diesel motor with straight veggie oil (SVO). you do need a small regular or bio diesel tank to start with and run before shut down. basically, the veggie oil wont fire via compression unless the motor is up to temp. so, you run diesel until the motor is at operating temp, then switch to regular old veggie oil. basically, you go to a fastfood restaurant and get some used grease (SVO) and put it in a barrel. after a few days, psyphon of all but the bottom 4" into another barrel. repeat a few times to get all the major particles out. install a filter inline with your new veggie fuel tank to catch the small particles. finally, instal a tank switch in the cabin of the vehicle and you're set.

i am actively seeking a diesel car right now to test this with. i'll let you guys know the results.

Interesting, I didn't know you could run SVO through a diesel. Let us know how it works. :thumbup:

It's very straightforward to turn SVO into biodiesel

indeed it is, but it is safer and easier to just run the SVO.

I'm aquainted with someone who has done so using used veggie oil. Works pretty well but when driving behind him you get very hungry. Smells much like french fries.

I know a guy who has an old bullet style bus that can start up on and run on straight vegetable oil. He doesnt need a seperate tank at all.

During the late spring/summer/early fall the engine fires up just on the veggi oil. Pretty amazing.

Diesel engines these days are probably near impossible to fire up on straight veggi, even on the hottest days, so a seperate take with diesel is required (or the extra step of making biodiesel), but this old bus starts up fine. When it get colder out, he cuts in regular diesel to thin it out.

Thats what the whole principle of Biodiesel is, that you can run it straight. Most of the times it will require filtering to remove all the particles that might clog up the injectors or fill your cylinders with junk. Sure you have to have regular diesel to get it going, but it is supposedly cheaper, however, when anyone opens a restaurant, there is usually a company in every town that will empty the grease traps for free, because it is illegal to just dump the old oil down the drain. Another prohibitive factor is people who live in colder areas. If it gets cold enough, diesel will turn into a slush because of its low freezing point.

I'm sure you could go to a fast food restaurant and just steal the oil from their grease trap, but I'm sure someone else comes out regularly to empty it for them.

not really... biodiesel is refined svo, you need lye and a fairly large set-up to clean it up/make it useable.

the whole principle of svo is that you can run it straight

non-reliance on petroleum?

when really examined from an economic point of view, bio-diesel is not feasible as a sustainable petroleum substitute. it certainly is an interesting project for an individual to function "off the grid", but that's about it, in my mind..

one cool thing about diesel vehicles, they run fuel through engine compartments and circulate it back through the gas tank to prewarm the fuel. also, the german u boats ran off of soybean oil. back then diesel was considered a useless by-product of crude oil.

I've always wondered if it would be possible to render biomass fuel from human waste.

actually you can use human waste to feed algae that can be turned into bio-diesel........

and also collect methane form human waste as well

yeh, i also saw the other day that the ice caps have methane that they are releasing at an increasing rate. they said it was a bad thing caused by global warming but i was thinking, hey, good thing, energy source!!! go global warming giving us energy.

not really, there is no economically viable way to capture the methane being released from the caps, as there isnt any to collect it from landfills, as well as cow farts.....

I don't mean to hijack this thread but have any of you read about thermal depolymerization - http://en.wikipedia.org/wiki/Thermal_depolymerization

I was reading up on this a year ago when I heard of a company using turkey guts to make gas!

http://www.designnine.com/news/?q=taxonomy/term/19

"A three year old Philadelphia project to turn waste into gas, oil, and minerals has been so successful that the EPA and private investors are putting money behind expansion of the effort. One of the new sites will be in Missouri, near a turkey processing plant. The energy recycling plant will turn 200 tons of turkey guts into 10 tons of gas and 600 barrels of oil. The gas is used to power the plant, which is 85% efficient."

Actually, bypass fuel is used to cool the injectors. It goes back to the tank so that new, cool fuel can be taken in with each injection. It would take a long time to heat a tank of fuel with bypass alone. SVO cars need to have all kinds of heaters and stuff installed.

yeah i was actually reading a 50 some page thread about that in the biodieselnow forums last night.

apparently some of their numbers were based on some bad data, but its still a viable option.... very interesting tech.
