Wiam
you can get into some problems using svo (straight vegitable oil) with certain engines that cause premature failure..........some of the kit sellers dont pass on this info

Also the kits can be easily constructed out of common household and off the shelf parts for 1/4 the cost.

The problems encountered with the DI type engine using SVO/WVO are that polimerisation of lubricating oil and unburned fuel. This is caused mainly because the fuel is thicker, leading to poorer atomisation especially when cold, and so there is a greater chance of unburned SVO accumulating in the piston bowl, (combustion chamber), and contaminating the ring-land area of the piston where it may harden and cause the ring to siese in its groove with a loss of compression. Also, affected would be the valves, etc.
Indirect injection engines such as mercedes older style excel with svo

Buzz I guess that will not work on my new tractor, it is direct injection. Thanks for the info. Could you explain a little more on difference between direct/indirect injection. I had figured cheaper ways than kit.

Well with DI it is critical to heat fuel to 175 f. Some manufacturers are better than others at tolerating SVO.
What can I tell more specifically

I remember hearing about these super carb patents back in the 50's. Back then I actually believed the stories were true, but now I know better. One of the problems with patents is they are a public disclosure of your invention, so anybody can read about your idea and even make one to use, but not to sell. There are certainly some patents that have been granted with some extraordinary claims, but they cannot be duplicated. Back then gas sold for twenty some cents per gallon and most cars got less than 10 mpg. You could even buy stock cars with two fours or even six two barrel carbs. Some people say the miracle carbs that were kept under wraps were actually fuel injection systems that are now reality.

Hydrogen has long been promoted as the fuel of the future and maybe some day that will be true, but it still does not seem to be making much progress. The first problem with hydrogen is that currently it takes too much energy to produce. The second problem is a huge one of logistics. If I remember the number right, Exxon has ten per cent of the gasoline market in the US today and they sell one BILLION gallons every three days. I can't imagine what it would take to produce, transport, and sell hydrogen that has to be contained under high pressures and replace even ten percent of the energy consumption in this country.

Bio Diesel can be burned in any newer diesel engines that has the viton seals in the injection pumps or fuel lines. The only problem is that it cannot be used in the colder temperatures unless you preheat the fuel in the tank. There are people running straight soy diesel in the summer, but they have problems even with blends when the temperature gets down close to freezing. The story I saw with the guy that burns french fry oil has a heat coil from the cooling system in his fuel tank and actually has a separate tank of diesel fuel for starting and warm up .

Indirect injection was the system in the older engines (7.3 Ford before powerstroke) where the fuel nozzle and glow plug were in a separate "prechamber" connected to the cylinder. In this systen the fuel could be injected under lower pressures and the injection pumps cost less. With the development of the new high pressure pumps, the engine makers can now direct inject into the cylinder. Direct injection results in a 15 % increase in efficiency and lower emissions.

I remember when gas was 25 cents a gallon. Of course, $2/hr was a really good job. Everything is relative.

As for the hydrogen, I saw a program on PBS about the new types of cars. They showed hydrogen technology in the US and in Europe.

In the US, they were talking about problems of transportation and storage. The arguements you just made. They sounded like we were pretty far from the technology.

In Iceland, they had stand alone hydrogen plants. The geothermals in Iceland make it possible. But, you could just pull up to the station and fill up like a traditional car. It made it look like we are pretty far behind in technology.

Some of the largest investors in hydrogen production are the oil companies. BP Shell and Exxon-Mobil are the biggest. I wonder if they know something we don't.

Like maybe we are burning through the known reserves of oil at an alarming rate?

I've been looking around the net and have found alot of plans and I think enough information to get a wood gassifier going. My question is, does any one have any practical experience to know ,since the size of the gassifier is built to the hp rating of the engine, how long on a 5 hp engine could you get one to burn between refueling as it seems to smolder. Lets say I was burning hard wood.

Buzz and I have exchanged info several times. He fully understands where the electricity comes from. Simple source. I am still wanting to develop the idea, maybe in Costa Rica.

The Ticos are very enterprising people.

I think I know what y'all are using but I can't find any reference on the web. How about a hint.

I'm in need of educat'n

Egon · « **Reply #27 on:** September 03, 2005, 06:59:00 AM »

Iceland has a Hydrogen gas filling station. It's made possible as they use natural thermal energy to produce electricity to produce hydrogen.

The easiest engine to experiment with, is an old "one lunger", like Jeff B and Harold are collecting. They can be used straight out of the field.

I once had an old "Edison" Genset and the original Nickel-Iron Batteries. I played around with it, whenever I was charging the batteries, to use for lighting in our house. I took a 100# Propane tank, with regulator, and ran a plastic line directly into the opening of the carb.

I had a petcock in the line, so I could adjust the flow. Too much would slow the engine and produce a little black smoke. Too little would bog the engine.

Today, everyone wants a "right off the shelf" get the best mileage possible, RIGHT NOW. What ever happened to EXPERIMENTING, people

I have the info for producing Hydrogen, but, I am not sharing at this time.

If some enterprising engineering type would like to offer a LITTLE time, to help me develop the key part, I would be more open with the info.

Today, I will start my first batch of Bio-Diesel. Even though I have to move, and have NO spare time, I WILL do this. Can't just sit around and complain.

Fla._Deadheader · « **Reply #29 on:** September 03, 2005, 03:07:26 PM »

UPdate

Got 3 test batches of Biodiesel sittin on the kitchen counter.

Where da heck is Buzz

? I got some note comparin to do

Right now, using excessive amounts for titration, I can see $1.40/ gallon. SHOULD be able to ½ that, at least

floyd · « **Reply #30 on:** September 03, 2005, 04:40:40 PM »

If 1 uses svo some modifications should be done to the powerplant. fuel does better if heated. powerplant lasts longer if started on dead dinosauers then allowed to burn off all svo by introducing dino back inso it will start on dino next time around

Also overlooked is the distillation process leaves some BAD by products. AKA hazardous waste.

Using WVO, Floyd.

I bought the plans for a woodgas generator from the Mother Earth News article RonW mentioned.I have been slowly gathering parts such as old hotwater tanks as well as researching all the information I can on the subject.Right now I'm having a difficult time finding the wider diameter bare tanks at 22".The most common tanks used around here seem to be 18" dia.
There has been a few updates on the plans from the original article on the gas cooler/cleaner and the nozzles(tuyeres) The plans include 3, 24"x34"diagrams with decent photos,measurements,charts and graphs to help choose the proper sized generator and nozzles as well as a complete materials list.

I plan on building the generator as a hobby much like I did when I built a Model A a few years back.
It was enjoyable to me and I learned a lot and met some interesting people along the way.

Here are a few more links to Woodgas

Pics,old and new

Great technical link from FOA

Fires that fit

For some really great pictures of cars,trucks,buses and even motorcycles powered by woodgas, run a google image search on either holzgas which is German ,or gengas which is Swedish.

Paul, To bad we are so far away from each other. I have a couple of those tanks laying around. I have always been interested in this also so keep us updated on your project. I think it would be a great fit for a saw mill. Heat and electricity that would be great.

I am collecting the makings of a biodiesel project myself. I will have to talk to Buzz and OWW on that soon also.

Paul_H · « **Reply #34 on:** January 25, 2007, 04:56:36 PM »

Farmerdoug,

I've been gathering up more materials and have decided to start on the 18" feed tank and the cast iron hearth while waiting to hear word on the 22"tanks.I have the local plumbers and the recycle centers(garbage collectors) keeping an eye out for the larger tanks.I've put up a $20 finders fee too.

The past few days I've poured over the plans and have some measurements recorded in my binder to make things a little easier.The hearth is two cast iron frying pans welded back to back with a hole about 3" cut out.One pan is 8' and the smaller is 6" and I'll keep it warm on the old BBQ while I tack it.
We still have to figure what vehicle we'll power with this but I'm thinking either a late 70's GM PU or a Ford ranger sized truck.Have to decide before I cut out the hearth.

How far along are you on collecting the fixings for a Biodiesel plant? There is a guy just down the road from me that has most of the major items but hasn't kicked himself in the butt yet.

Fla._Deadheader · « **Reply #35 on:** January 25, 2007, 06:40:21 PM »

Paul, is it possible that you only need 55 gallon drums.

They measure 22" across

Paul_H · « **Reply #36 on:** January 25, 2007, 06:56:52 PM »

Harold,
I was hoping to use a HW tank because I like the looks of the domed top for shedding water and also the lid design that comes with the plan but I'll have a good look at the 55 gal drums too,thanks.

farmerdoug · « **Reply #37 on:** January 25, 2007, 07:04:07 PM »

Paul, I have about half of the items on my list. The project is in the garage which has no heat and an air door so it is on hold at the moment.

Check with the well guys too. I think a water tank would work great.

FD, I would not use a drum as the thin metal will burn out quickly. The metal of a water tank is much heavier and will last alot longer.

Farmerdoug

Fla._Deadheader · « **Reply #38 on:** January 25, 2007, 07:31:06 PM »

I've seen Barrel stoves last for several years. Just use hi-temp paint

Might be that cold water tanks are a different size

They have domed tops

SwampDonkey · « **Reply #39 on:** January 25, 2007, 08:14:03 PM »

Let's make Hydrogen with soda cans

I know the guy in the article, right up your alley Fla_Deadheader.
