AltFuel Veggie burner

[Radd Cruisers]

Well, its been a year since buddy went to veggie, he has burned over 600 litres, his fuel bill has went from 500 to 50$ a month and no shortage of oil.

I would definitly go this route with a inexpensive BJ60.

Maybe even a HJ61.

 

[brownbear]

500 a month is pretty high fuel bill.... veggie was made for him.

Ask him though how much time does it take to find all the oil... I am curious.

Also anymore detail about what it's in?

Your math doesn't compute... 600 litres for 50x12 = $600? Surely you meant 6000 litres...

In any case, going down to 1/10 is great, I guess it's the cost of hauling the oil?

With home grown bio the cost, I'm told, is between 1/4 and 1/2... (still lookinbg for a cheap source of methanol in Montreal)

Diesel is almost a dollar a litre, so 600 litres is 600 dollars??

He is running this system in a 1982 BJ60, body at the high end of rust.

Oil is easy to find and he now has more than he needs and has told two restoraunts no for now.

Yes I know, but you're saying his bill went from $500 a month (that is 500 litres at 1 doillar a litre, for a month, isn't it?) to $50 when he switched to veggie (oil). Yet you say in your first post he's burned over 600 litres for a year...

Isn't that a bit confusing?

That's encouraging news as I would expect supply to become scarcer when petrodiesel prices climb up... I'm presently looking at the feasibility of making my own bio at this time, and I need a suply of free oil for at leat two years (6000 litres) to offset my future equipment investment...

Yah I read it this way too.

I think it was meant 600 litre a month... No?

 

[haryv]

Is he running pure WVO or biodeisel?

 

[prairiecruiser1]

I run pure wvo in my hjz77. I drive about 4000-5000 kms a month and spend about $80 a month on diesel. I filter and pickup my own oil and spend about two hours a week or less in the garage to do it. not bad

 

[Abitibi]

Prairiecruiser, are you related to Prairiesafari? The HZJ77 was my 2nd choice after my Nissan Safari, they are beautiful truck! Just lacked a bit of interior room for my needs.

Glad to hear your running full wvo. I converted my old Delica a few years back and ran it problem free for 2 yrs before trading up for the Safari. I just started converting this one, can't wait to be done. Once you've experience the freedom from the pump it's very hard to go back...

As for filtering time it largely depends on your system. I'm doing cold upflow filtering and it takes me 2-3 min/day for 40L of oil plus 1hr/2wks to pick up the oil. Funny enough I don't consider this work, more like a relaxing hobby!

Cheers

3+ years........

I've been running WVO for over three years to the coast and back for surf trips and it's been great. The truck runs better on grease in my opinion. I filter in 4 stages in my garage down to 1micron. This I believe alllows my rig to spare the onboard fuel filter for longer. I also change my oil about 2x as often as most as my turbo needs nice new oil and it gets wicked hot going through those lines. It's a good idea to throw an oil sample in the freezer to see if there's polymerization, coking and fuel in the oil.
I love grease and it's more like a hobby. I spend on average, an hour per week working on fuel. I just drove 1400kms last weekend and didn't spend one dime on fuel.

I think it is easier to get the oil on the island then in the greater gvrd area. West coast reductions pretty much has the monopoly of collecting oil in the lower mainland. I see there oil containers everywhere.

I have run it inside my truck. But for some reason, over a month or two, i started getting worse and worse fuel economy. Performance did not change much. It was getting so bad, I decided to take the injectors out and have them rebuilt. I cannot recall the diesel rebuild shop on river road, but the owner said my injectors were worn at the tips. After I picked them up and installed them, my fuel economy returned to what it was if not a little better.

I wonder if the WVO had anything to do with this. I pre filter the oil with a goldenrod filter, and pump it into my tank. The tank then send the fuel down a line, where it is preheated with two lines running beside it and wrapped with water line insulation. It enters a racor 10 micron filter, then on to the plate heat exchanger. BTW, the fuel coming to the exchanger is a clear golden color. Filters did there job.

The fuel coming out of the heat exchanger goes into a transfer switch so I can select diesel or WVO.

I do not have a temp probe to tell me how hot the fuel is.

Anyone know of a temp probe that I can install a inlet and outlet line to at the feel feed to the Injection pump?

Anyway can anyone here guess as to why I had fuel injector wear at the pintle? Can wvo do this? Would the acid in the wvo do this?


Its been about 1.5 years since running wvo though my system. Perhaps I can give it a second shot. But would like to make some changes to my system.

Thanks

I use a meat thermometer. It has a 10 cm probe which I attached next to an injection line, and a long lead wire that goes through my firewall into the digital readout on my dash. I get an accurate reading of the temp of my WVO as it goes into my injectors (I have to assume that the reading on one injector is indicative of all the injectors). I got the meat probe at a grocery store.

 

[Tim-HJ61]

Maybe even a HJ61.

There aren't that many 12H-t's running on vege. I've run mine for some five years and 70,000 kms.

Let me know when you're ready to take the plunge and I'll guide you through my installation and how I would improve it.

That's being pretty particular. What are you trying to clarify??

I use a electronic coolant gauge on the outlet of the Heat Exchanger and that shows 80°C. You could install one, or two, or three into a 15mm Brass T pieces on the fuel line anywhere and have the probe right into the fuel flow.

By measuring on the outside of the injector line, you are assuming that the injector line transfers the heat accurately. I don't believe this to be the case. I believe the fuel/vege is a lot hotter than the outside of the injector lines. As my previous paragraph, the oil is at 80°C at the outlet of the Heat Exchanger - a 30 plate unit. The return feed from the back of the IP circles back to the inlet of the lift pump to be heated again. The line coming out the back of the IP is very hot and there appears to be minimal temperature loss inside the IP. I could measure this with my infrared temp gauge if you like and get back to you later.

WVO vehicle don't like to idle, slow city traffic or driving like a granny on the hwy. It seems to cause premature failure of the injectors. That might be the reason why your tips were worn.

You'll have better success on veggie if you push your truck a bit harder on the hwy (keeping an eye on your egt) and avoiding idling and slow moving...

Good luck!
Mr D.

Actually, I was responding to the question that Haryv asked:

Sounds like you have a good setup with the electronic temp sender. I used my method because it was simple, inexpensive and it measures the WVO temp exactly at the point the WVO goes into the injector (I get a reading of 70-75C). As you suggest, there may be some heat loss through the injector line, but its wrapped in high temp tape to insulate, so it shouldn't be much. In your method, there will also be some heat loss by the time the WVO gets to the injectors. In either case, there are unknown variables. Like you say, checking with an infrared thermometer would give more certainty.

He had it in a 1982 BJ60, he owned a restaurant and was good friends with the folks across the street who owned a french fry joint.


I think he was heading up to the west coast a couple times through the week and doing some surfing.

Back when diesel was like a 1.40 a liter I was driving from Nanaimo to Duncan and my monthly fuel bill was quite high.

My FJ60 cruiser from Idaho which will be getting a 3B, might in the future go on this veggie diet.

[crushers]

well, i am looking at taking the plunge.
the wife was complaining about the cost of fuel in her gasser car (26.8 mpg average in the winter and 32 mpg in the summer) so switching to a diesel cruiser would solve nothing.
we looked at getting a diesel rabbit or jetta but at $4K to $7K it just didn't make any sense.
she then said she would be willing to drive the land cruiser on WVO if it saved us significant amount of $$$ but not otherwise.
i have been spending the last 3 days looking over the costs and time consumption of getting set up properly and the down sides of getting the WVO, settling it, seperating the s*** from the good stuff, filtering it, sticking it into the cruiser (87 BJ70 ragtop) and the cost of the system for the truck. not sure if the savings are there or not.
she drives 50Km each way each day and another 100Km to 150Km on weekends.
when i drive the diesel tow vehicle i usually am putting on 2000Km to 10,000Km on a single run towing the float and the Cruiser. on those occasions i can see the value but that is only once or thrice a year.

talk me into it or out of it guys.

cheers
