cool idea

[rwdriver]

what about putting an electric heating element on the injector lines.  before you start the car, you would preheat the lines, then you could start it on straight wvo. this would make it so you could allways run straight wvo. any thoughts?

As it happens my bro came up with this exact question over the weekend since he doesn't have room for dual fuel tanks in his T4.  Then we asked ourselves:  what about the IP thats full of gelled WVO, and the hardlines between the IP and injectors that are full of gelled WVO, and the injectors themselves that are full of gelled WVO.

Hmmmm... we decided it was back to a dual fuel system... but perhaps someone has come up with a way around heating the fuel in those areas as well ??

Keep it in a heated garage

Make a dual tank but make the OG tank WVO and then like a 1 gallon tank somewhere else in the car for diesel for starts/stops. Nice and small, could put it pretty much anywhere

[jimfoo]

So if your main tank jells, how do you get the fuel out of it?

[burn_your_money]

circulating engine coolant lines around the tank or coiled up against it, 1 gallon should get you about 30 miles which should have the engine nice and warm and the fuel warmed.

hmmm...  you would need way too much energy to heat the WVO at the injector lines I believe.  you need to penetrate the the steel injector line.

why not make a thermos to hold your WVO?  heat it up and it'll stay hot for a few hours or more.  the initial start in the morning would be on diesel, and for the rest of the day it could probably just keep up with WVO.  maybe insulate the pump too?  the pump will cool down considerably from the cold air rushing through the grill.

damn so much work to to convert to veg... makes me want to run an old merc    straight veg!

[harry_the_face]

I have rad about just cutting the WVO with 50% diesel in the cold seasons and running a one tank system.  I thought about experimenting with it.

[jtanguay]

why not just keep a small container of diesel under the hood??? @ 5L/100km and 3-4km to heat the engine that is about 0.2L per warmup?

another idea would be to install a lift pump & heater, and have the lift pump circulate the 'hot' veg through the pump for a minute or so to help un-gel it.

Don't be lazy. Do it right and go two-tank.

damn so much work to to convert to veg... makes me want to run an old merc Cool straight veg!

NO diesel engine should EVER be run on straight vegetable oil. They were not made to do so, it will harm the engine and injection system.

[the caveman]

just heating the lines is not enough unless it's real warm out. the motor will start on the warm svo that's in the lines but then the pump will be forcing to pull that cold oil through the filter and lines. the diesel veg heaters are okay but do take some current and are really meant to be  on while  the motor is running.
OM617  any diesel can run on straight svo or wvo. heating the oil to the right temp  and proper filtration are the key. the diesel engine was designed to run on peanut oil.
the person who got me interested in this has been running his rabbit and then golf for 15 years on mostly wvo and a combo of diesel, wvo and biodiesel .

Right, which is why two tank is the only correct way to do it.

the diesel engine was designed to run on peanut oil.

Completely incorrect. Mercedes' and VW's engines were NOT designed, built, tuned or even imagined by Rudolph Diesel. They were the designed some 70years after the first practical Diesel engine was made and some 60 years after Dr. Diesels death. Technology made HUGE strides in that time and Diesels have next to nothing in common with the first engine and were NOT "designed" to run veggie oil/peanut oil/waste oil, to state otherwise is a fallacy.

[the caveman]

so the gasoline engine design from 110 years ago is obsolete also?  i,m not talking about differences in pump or injectors or whatever. we are still trying to figure how to make a pumpe duse work properly. the principle of how the diesel motor works is the same as when it was designed, even 2 stroke diesels. if these modern diesels can't run on svo then how do you explain the thousands of vw's and merc's out there that are? the only vehicles i've had problems with are pre 95 GM ' s, which are garbage at best anyways.

[the caveman]

and that's why i've never even seen a v10 toureg. manufacturers are only interested in the bottom line. because of the poor quality of fuel here in canada and particularly quebec we will be the last to see what probably was and is North america's largest diesel market. older vw's [pre tdi] and merc's can run on almost anything. as emission controls and fuel management develop some engines probably won't be able to run on anything but high grade diesel fuel; but as far as the motor itself, if it has more than 19/1 compression it'll fire up.
i have heard that the largest diesel "motor" in the world will soon run on svo. it's a giant piledriver, at least 10 ft in diameter. it's basically a 2 stroke. they pull the piston up by crane, drop it while shooting some fuel at the bottom and BOOM there it goes up and down till they stop shooting fuel into the cylinder. it's crazy ass big.and cool
