I am in the process of converting a 6V92TA to burn recycled vegatable oil, a waste product of restaruants. The conversion is quite simple and involves the installation of a 50gal tank for diesel and conversion of the main tank to store and heat waste vegatable oil (WVO). The science: Diesels were originally designed to burn veg oil and even modern engines will burn WVO as long as it is heated to 170F (at this point the WVO's viscosity drops to 10 centistrokes, diesel fuel has a viscosity of 10 to 15 centistrokes)and burns cleanly and efficiently. Common issues: Coking: if the WVO is left in the injection system and burned as a fuel before it reaches 170F it can and will coke the injectors causing poor spray and the consiquent engine damage. Jelling: WVO becomes semi-solid below 40F, if left in the injection system below this temp, the WVO will clog the lines, injectors and pump. To avoid these issues two fuel tanks are used, the engine is started on Diesel and run to temp, the engine coolant heats the WVO and when 170F is reached a switch controlling an electric valve switches the fuel from diesel to WVO. 5 minutes before the engine is shut down it is switched back to diesel and run to purge the wvo from the fuel system. Advantages: WVO burns very clean reducing emissions by 60% Being made from plants which producted the oil by pulling carbon from the atmosphere, burning this product only puts into the atmosphere the same carbon which was used by the plant, and thereby does not contribute to green house gasses (unlike fossil fuels which pull carbon from deep within the earth and introduct it into the atmosphere) so you can hug a tree while driving. WVO is free, most restaurants pay $1.25 per gallon to have a company take it away and will be more than willing to let you have it. WVO is completely non-toxic and biodegradable. Simple, all you need to do is fill up at any McDonalds. Disadvantages: System must be installed. I have a VW diesel engine which has run WVO for about a year, I have taken it apart and all looks good. Many other engines have been converted including several GM units run as public transport, none have shown abnormal wear.

Chris, My own personal opinion is that unless you do a lot of miles, in otherwords you are on the road 50% of the time, I cannot see any real advantage considering the costs of the instal and the dangers and costs of breakdown due to coking, etc. Great for companies who have a fleet but not for an individual bus. Another thing to consider is whether one can get the oil as I have heard that a lot of major chain restaurants are not allowed to dispose of this oil in case the remover dumps it down the road or even causes a spill at the restaurant and the restaurant is liable for the clean-up. Also, a lot of them already have contracts for the removal. Like a lot of these great ideas, before long government will find a way to tax it and then it won't be cheap anymore. Peter. | ||

Chris considered doing the exact same thing.. The one problem I came up with was filtering. When I need to have a fillup is when I am on the road. If I am out an about traveling I would have to stop find a source with 100+ gals, then filter and fuel the bus. Sounds easy when you type it but a task when you would be actually doing it. I could take extra pre-filtered fuel with me. If taking pre-filtered how much? Depends on lenght of trip right? So I take the bays of the bus fill them with 55gal drums to transport fuel with me ready to go with pump to make fillup easier. Conversion is easy.. I would however if It was me instead of converting main-tank just add 2nd tank for WVO. This would allow the system to revert to normal usage with just removing the spare tank. Could a tank be built that would take up the entire 1st bay allowing maybe 400 gals of WVO to be carried? What about the extra weight of 400gals? How much does oil weigh? Oil appears more dense then water so maybe 10pds to a gal? What would adding 4000pds of extra weight to center of bus do? The biggest problem I see on the scale of use is the refueling when needed. I will convert a toad to use wvo where you can take 50gal with you with little problems. Just my thoughts.. | ||

It's becoming obvious to me that not only is this a good idea, it's in our national interest to find alternate ways to supply our thirst for fuel in this country. We are about 5% of the worlds population. We use about 30% of the resources. We create about 50% of the waste. The rest of the world sees this and gets pissed. One of the things I'd like to try is to pre-heat a smaller portion of the total supply of wv oil in order to be able to bring the system up to operating temperature quicker and also to cut down on the total amount of heat in the system. This might be done with a small insulated tank with a demand valve similar to a house type toilet tank. This would be a sealed tank with a failsafe overflow path back to the main wvo tank. What I'd really like to see is for the people of this country to lead the world in the areas of inovation and responsible use of this earths resources. I'd gladly pay tax on filtered wvo at the pump if that tax went to front a chain of alternative fueling stations. Bob | ||

Oil weighs less than water. SO your calcs are off a bit. I think one of the biggest hassles to this system is the filtering process. It takes a long time to filter all that WVO. To make a good system, I think you need a way to force filter the WVO in a reasonable amount of time. I.e. filtering the next batch the whole time you are driving down the road burning the previous batch. Not standing around in the MickyDees parking lot waiting for the WVO to filter thru. Travel in winter months makes the filtering that much slower. Also, in a DD two-stroke the injectors are cooled by the fuel and the excess is returned to the tank. So you would need to pre-heat the WVO so it can flow, but not so hot that it defeats the cooling of the injectors. Also, need to consider how the return flow of WVO will be re-routed so your switch-over valves really would be switching the supply and return lines. I certainly like the concept. I would love to run my bus on WVO. But I just don't have space (no bays) in my bus for the on-board processing equipment that I think you will need to make it practical and not just possible.

Hate to say it, but the first paragraph in the heading "Advantages" is totally without logic.

I believe I would check Your source in regard to restraunts " paying $1.25 a Gal. to have this oil hauled away " Actually this " Oil " is not really free. As a matter of fact this "Oil" is being sold to rendering companys by resturants. ( In some large chains it's actually figured in their profit & loss } I know this as a fact in the Mid-West & also Texas. { Texas find a guy $350 for helping himself to some of this " FREE OIL " } A lot of these tanks will have a padlock and the name of the owner. Most of this " Oil " is "cleaned" then sent to feed mills were it is mixed with livestock feed. It is a big enough industry that a co. in St. Louis is actually building tanks with heaters to place at restraunts to make pumping into tankers easier. When I was working we serviced a large fleet that hauled this "Oil", they used regular Diesel fuel in all their semi's ! I read a article about some guy's going to Mexico from the East Coast, I believe in a converted VW but could not find any " Free Oil " in the South-West. Remeber a Detroit uses it's Diesel Fuel to cool its injecters. There just ain't no Freebes left in this world ! Jose Just a dumb retired mechanic | ||

WVO it appears to be maybe heavier then actual oil. I dont know for sure that this is a correct statement.. I do know that oil floats on water but water seems to float on WVO. Maybe just a oddity. Seeing that the bus being considered has no bays I guess it is moot using one for storage. To make it work you still would have to carry enough WVO with you to use. | ||

Heating: I plan to use engine colant to heat the entire fuel tank as the oil runs better when warn and what the hell, it makes a great heat sink, then the oil will pass through a 1/2 ton refrigerant heat exchanger just before the pump. In practice this would be all you would need as long as the temp did not drop below 40F. Collecting: I have had no problem at all, every restauraunt manager I have spoken to has been very helpful and kind, I have even been given a free meal once! As for contracts Hmmmm, no one has said anything except one IHOP manager who told me that he would have to pay less to the disposal company and that would make his weekly profit go up and put him closer to his bonus. I planned a trip to Colorado this summer (I am in WA) and looked up restaurants along the path in a AAA road guide, I figured that Mexican food, fish and chip places and burger joints would have the most and I called several. I explained that I was driving a bus converted into a motorhome on a trip with my family, explained that the bus was a non-polluting experimental project which burned waste vegatable oil and asked if I could stop by on my way and "fuel up". Without exception every single place I called said they would be happy to give me all I could carry averageing 30 to 50 gallons, two said they had a 400 gallon tank I was welcome to. As for fear of spills... WVO is non-toxic and as far as I have found the EPA has no hazardous waste handeling sheet available for it or for salad dressing either. No one has said a thing about possible french fry liability. Filtering and tanks... Once heated the oil will pass through a Racor AF1000 filter which is a high volume diesel filter (.5 micron), in my system it first passes through a particle filter which pulls out any large bits, and the pick up tube which is inserted in the oil at the restauraunt, had a 40 micron screen in it. The tube is suspended in the oil tank and WVO is pumped via a transfer pump at 5 gal per minute through the filters and into the bus tank. Tanks: I plan to use the main tank (140gal) as the grease tank as it is larger, I will only be starting and shutting down the bus on Diesel so I figure a 50 gal tank will be fine, if one liked there is no reason that you could not fill the grease tank with diesel and if you wanted to reverse the conversion, simplu disconnect the coolant lines running through the copper coil installed in the fuel tank, remove the switch over valve and everything is as it was. Coking: As long as the engine does not burn grease at less than 170F, this is why you start on diesel, and all the WVO is purged from the pump and injectors prior to shutdown (run for 10 minutes on diesel before shutting down) there is no issue with coking. This conversion has been done a hundred times on farm equipment, semi trucks, urban busses, etc. The guy who owns www.greasel.com is converting his MCI! Return line: Use a 6 way solonoid valve and the return line is routed back to the pump inlet when on grease, otherwise the unused grease would be pumped back into the diesel tank or visaversa. All this is in the plan but a good point. As for cooling the injectors, when the engine is at temp the injectors are hotter than 170F simply because they are part of the engine, the preheated WVO is at the same temp as the coolant, which is less than the temp of the engine. Space: the whole transfer pump (to suck the grease up) filters and valves fit in a spacee slightly larger than a shoe box. If space is really the issue and there is no room in your plan for an other 50gal tank, the main tank could be devided. You would still have the same capacity but it would be split between the WVO and diesel side. BTW the WVO can be kept in a plastic marine tank and is as safe as transporting salad oil from the store to your home. Chris | ||

There is a yahoo groupjust for busnuts to exchange information on useing SVO or WVO. http://autos.groups.yahoo.com/group/wvobus/ Personally I intend to add a 150 gallon WVO heated tank in the rear bay of the 4106. At 8 to 9 MPG this will give me a range of a thousand miles at a cost of .25 to .30 cents per gallon versus 2.00 a gallon for dino diesel. New SVO can be purchased at almost any resturant supply company under 2.00 per gallon so at todays prices for diesel its still cheaper. Several motorhomes are already running on WVO without problems. There is a Mack semi on the greasel website that I contacted the owner. He now has over 100,000 running on WVO without any major problems. The power and milage are the same as the dino diesel, the emmisions are far, far less. No internal modifications are done to the motor. Your diesel genset can also be run on WVO.

Which one costs more? Finding out the engine runs on WVO or finding out the engine doesn't run on WVO? Of course theory is good, but I, like others, would be seriously concerned about the cooling of the injectors if the fuel being put through them is 170F to begin with. Not saying it cannot be done, but I would be extremely cautious about it... One other thing, Biodiesel and WVO concepts have been around since what, the early '80s? Why hasn't it caught on yet? I have yet to see any documented proof of a VW Rabbit or Jetta, or Golf running the 400,000km (sorry, Canadian here) or more that can be expected out of a dino-diesel engine. | ||

Henry B, I just read your post, must have skipped over it or my mind simply blocked it out due to it's lack of LOGIC. "It does not matter where the stored carbon comes from...either from tiny vegetable forms layed down..millions of years ago as coal or oil, or from the carbon taken up from the plants today...that are "recycled" as vege oil, carbon in the atmosphere is carbon in the atmosphere." Perhaps a little history refresher would make it clear: Long, long ago the atmosphere was much different than today (skip ahead) micro-organisims began to break down the gasses in the atmosphere and minerals in what was then the sea (skip ahead again) as these organisims died and settled they took the carbon with them and formed large deposits which form the oil we use today. Now if you can not see the difference between re-introducing that carbon back into the atmosphere and using carbon which is present in the current gas-plant exchange then think of it this way, one way adds carbon to the current atmosphere, the otehr does not. | ||

I imagine that would be readily available around the country at low cost or free, too. Also, back in the '80s, there was a lot of experimenting with pure alcohol in gas engines, where did that research lead?

I am certainly not opposed to new ideas, I'm just too timid to try them without a lot of information to support their practically" I was reading about the future in the past, when they were just beginning to make cars with engines. The big discussion was what fuel to burn. The first cars, according to the article, burnt ALCOHOL to run down the (not yet) roads of America. When Oil was found and it was cheaper to make gasoline than it was to make Alcohol, they shifted gears and fueled the cars with Gasoline. The technology for Alcohol burners is in the archives of the auto manufacturers. I would think, if it did'nt show up back in the 70's when we had the energy crisis, then there must be a reason that it was not brought back to existance in the transportation market.

"His" process may be patentable, but, there are many processes already being used that you can do at home with very little cost to you. As far as supplies while on the road, there are now several small compact filter units being made and soon to be more efficient units as the incentive grows due to higher and higher fuel cost. Be practical, just how many gallons do you use yearly? How many trips over a thousand miles round trip? Lets say you use around 120 gallons for a weekend trip, at 2.00 per gallon (don't you wish California) thats $240, at >30 cents per gallon for filtering WVO thats $36, a savings of $204! Thats just one holiday weekend trip. Now WVO weighs less than water (oil floats on water) I took a sample and it weighed 7.7 pounds un-filtered. Smaller fresh and black water tanks leave room in the rear bay for 150 gallon of WVO. Another tank under the bed above can store another 100 gallon to refill my heated tank as needed by opening a valve, easy and simple! Now I have around 230 gallon of WVO useable, or, aprox. 1850 miles without refill at a cost of $69, if that don't excite you than nothing will. http://autos.groups.yahoo.com/group/wvobus/ and check the files section for good information sites.

" No, but I'm not going to be the one to make the documented report and then pay several thousand dollars to have my Series 92 engine repaired after the experiment. The DD mechanics I have talked to doubt waste vegetable oil would work in the 2 cycle engines for a number of reasons, the main one being that these engines use the fuel to cool the injectors. Preheat the fuel, and you defeat the injector cooling. Now, I don't know how running the injectors hotter than normal would affect their life, but I'm not going to be the one to find out. Another point - the 2 cycle Detroits are direct injection engines. A number of the reports I have seen regarding waste vegetable oil performance in direct injection engines is that it doesn't work too well. Engine operation tends to be rough at idle and combustion isn't very clean. Indirect injection engines (using a prechamber) seem to work on vegetable oil quite well. The prechambers seem to aid the initial combustion upon injection. By all means, if you have a bus with a 2 cycle Detroit engine, run it on vegetable oil and let us know how things turn out. I won't take that kind of chance with mine. | ||

niles, the WVO supply line is wraped together with the coolant lines that heat the WVO tank. The supply line will heat befor the tank is heated. The solonoid to switch from diesel to WVO is located close to the motor fuel pump so the flush time is 5 minutes or less. BTW: there are no EPA regs to worry about, WVO is considered a food and can be disposed of as you would a half eaten burger. http://autos.groups.yahoo.com/group/wvobus/ | ||

Maybe you can dispose of it where you like, but don't dump it in the trash can, it would soak through the paper bag the burger came in. I read there was a problem with hot fuel and therefore not cooling the injectors on 2 stroke diesels, maybe 4 strokes too?? Nah, sorry, you can keep the "Greasel", my motor is too valuable to mess with and all that smelly goop too, slopping about in the bays, yukk!!! Just my opinion, but don't park next to me if it's at all smelly, thank you. Peter. | ||

Peter, no one is trying to talk you into doing anything! Your opinion has been well stated. As soon as the Tech's answer my question about allowable injector and fuel temps I will be glade to post it, pro or con. Until then, if someone has information other than "I heard" or "my mechanic said" please post the source, I would like to know too. So far everyone that is acually 'doing it' has stated no problems and some have over 100,000 miles. | ||

Smelly? Yes--it smells like whatever was cooked in it. | ||
