Herb..because SVO is too thick for a vp-44 and won't thin enough even as the natural heating processes of the fuel system before it hits the pump and injectors..so it'll run for awhile, but not forever.As far as a common rail..i am speculating, try at your own risk.And for everyone else..stop thinking about the peanut oil..a} it's much more expensive than Soy b}It's not as pure as Soy {at least the Costco brands}.

 

Hear you all talking quite a bit in awe of peanut oil. The great man himself. Rudolph "Diesel" ran his demonstration engine on Peanut oil. So the first "diesel" engine ran on peanut oil. Just a bit amazing that here we are going full turn and back to oils besides dino types.

 

What happens if you run it in an engine like the CUMMINS ISB 5.9 DIESEL,which is 24v, Common Rail?

 

Well it's funny you should ask. You see newer engines have been designed to more effiecently burn a specfic type of fuel "#2 Diesel" which, I beleive, is located in the cracker between MGO (Marine Gas Oil) and #2 Kerosine.

Fuels like Peanut oil or for a better term SVO / VVO. Still have quite a lot of glycerine in thier make up. That lowers thier Cetane somewhat. They are by definition an imperfect fuel.

What people have to understand is that they will burn and they will run on 24V engines but to do so much less efficently. ( less smoke) you have to reduce the Glycerine by Processing it in to Biodiesel
OR
You can heat it up before you burn it. This reduces the amount of heat the engine has to impart to the fuel as a part of compression. (diesels ignite thier fuel by the heat of compression.

Just a side note. The most efficent Diesel Engine running today to my knowledge is manufactured by MAN-B&W. (Germans go figure) This engine is more than likely the size of your house. It's 3 stories tall. Can have between 6 and 12 cyl's. It's a 2 stroke uniflow design. And it' burns IMO fuel. IMO is a few grades above Tar the stuff your diveway and highway has in it. IMO has to be heated up to 180+ deg F. These Engines run on IMO and move products on vessels from China to the West Coast as well as all over the world. These engines can be from 10, 000 BHP to over 100,000 BHP.

Hope that answers your question.

 

Have you heard of anyone using this biopass filter system that uses these acuscrub 'beads' to remove the glycerin in the oil?

http://www.hydrogenappliances.com/bioD.html

Assuming you do some filtering like this, then the oil will be ready for 24v or CRD engines, right?

 

I don't know anyone using this system. But it looks like a big Racor system. Homemade. Looks sound in process but I'd not expect any miracles.
Don't confuse my statements -you could use Peanut oil in a 24V eng. The problem will remain of fouling up the valves with by products of combustion These newer engines are built to get all the power it can out of every lb of diesel fuel. But there is no reason someone could not use a 80/20 mix of VVO and Petrol Diesel without any poor results long term. You could even go as high as a 50/50 mix and actually have some long term benefits. You see the new EPA diesel will have even less sulfur than now. Sulfur is bad for our air but it oddly is good for the engine as it acts like an additional lubricant for the HOT parts of the eng. Like piston rings. Biofuels add back in that lubricity factor in a vegetable form. To much and it fouls your valves. Instead of building an engine that maximizes the output for Alternative fuels. The engine manf have been targeting making an engine that will burn each lb of diesel fuel cleaner. Blame California. If they put the same effort into the tweaking an engine to burn Vegetable oils cleaner and more efficiently then the emissions would be cut by over 1/2 as vegetable oils have like 20% the total harmful contents of diesel fuel. Diesel engines of any kind are much more forgiving than most people realize. I've seen them run on fuels that would make a Shop technician cringe. At over $3 a gal for diesel necessity will be the mother of invention.

They have a whole slew of home brewers and guys that have been working this problem at every angle for years.

 

I think we have a mix-up of terms here. Glycerin does not come into play until you start the transesterification process to which it is a byproduct of that process. When you are talking straight veggie oil it is fatty acids you are dealing with. When you are dealing with straight veggie oil your main concern is, how much animal fat is in the oil, is the oil hydrogenated and suspended water (a concern with waste veggie oil). STAY AWAY from hydrogenated oils. It has been linked to really messing up an engine. From what I have gathered when the oil is burned it leaves a varnish like coating on the pistons and rings and causing the rings to seize (this is a real problem with a lot of idling). The suspended water is bad because when it makes its way to the injection pump and injectors the heat will cause it to flash to steam so I have read. Do some searches here for more info http://biodiesel.infopop.cc/groupee/...rm/f/159605551
You might want to do a search on the “acusorb beads” to see if anybody there has used them.

 

Not quite, common misconception. Sulfur does absolutely nothing for an internal combustion engine's performance.
Problem that arises is when sulfur is removed lubricity is removed with it and must be added back.

 

AFAIK, theres nothing you can do to remove the glycerin except to do the transesterification to pull it out.
Theres an list of iodine values out there for different oils. a lower number means a lower chance of polymerization (forming a hard plastic-like coating on the internals). I think soy and canola were good to use. I think peanut oil was a bit higher. Ive got a bazillion links to different websites with info on this stuff but there easy to find with google.
Avoid oil with high water content. Its the cavitation that is an issue inside the IP. Some folks swear by flashing the water off by placing the oil in a vacuum vessel and sucking it out from the top. Some folks just heat it for a period of time. You could maybe run it through a dessicant but youd need to regenerate the stuff every so often with a lot of heat.
I decided to go with a conversion instead of making biodiesel since I dont want to be dependant on a petrochemical for a fuel ingredient.

 

Bill,
Sorry it took so long for me to get back to to you on your reply.
I have to disagree. The effects of sulfur on a small 4 stroke 200-300hp engines may not be apparent to the casual user. However as a Chief Engineer on a Diesel Electric Power driven ship with 4- 2 stroke EMD 12v645 & 16v645 F7B model engines I can attest that the reduction of Sulfur has shown a marked increase in wear on top end. A recuction near to average 10K hours of service life has been observed. The problem has been such that engine manf have started upgrading some of thier parts. EMD is now delivering new Injectors (Ecotips) and Upgaded Heads and valves. I have torn appart engines from 20,000-9,860 BHP 2 Stroke Slow speed Sultzer & MAN B&W Engines down to Detroit Diesel & Cat applications 300BHP 4 stroke units and have seen the diffrence in reduced sulfur fuels and it's corresponding wear on top end components. Biofuels have shown that they add an increased lubricity that repalces a degree lost in low sulfur fuels.

 

I looked into the accubeads also , I wanted a way to process waste vegi oil in the bed of the truck [ I'm a full time RVer ] and when I 1st heard of the accubeads I tried to find out more , but most of the forums , would just jump all over any mention of then , [ I try to find the reasonds why or whynot , when looking for info , but never got any reasoning , just beleaver responses ]
Then I found a company that made bead filtering producs , and never got a responce from them ,
The search is still on , but after looking at 5-6 university studies , it seems like transesterfication is the way to go , but I am stilling looking at the preheat waste oil , hydrogenated ? ,
Its good I do not have the space to build a processor rite now , it forces me to get more info .
Thanks , keep it coming .

 

I know this is an old thread but just wondering about the peanut oil. So after reading most of the posts are you guys saying the the first gen 12v would run great on peanut oil??? diesel is up in the 4.50 a gallon here in CA. so buying 5 gallons of peanut oil to run in my truck is a nice cheap way of saving money. So let me know. please.

 

I used peanut oil in my 2006 Dodge. The oil came in 5 gallon jugs from Costco. I haven't been able for find it there for years now. I would add 5 gallons of peanut oil to the fuel tank with every 5 gallons of diesel fuel. The truck ran perfectly.

 

DO you have to mix it before you put the oil and diesel into the tank or do u just dump the oil in and then the diesel and let it mix in the tank?

 

I would stop outside a truck stop and dump in up to 15 gallons then drive into the station and fill up. Sometimes the mixture was probably more that 50% peanut oil, and sometimes less, depending on how low the tank really was. I had no problems at all with this, even when I had a heavy load. My usual load is a 4000 lb 12 foot Lance truck camper with a 3 horse trailer behind. In the scales it weighs around 21,500 lbs total. Also, I live in Arizona and drive the mountain roads a lot.
