Beautifying the DES 8/1

[LowGear]

mauicole; 

I am currently running an 80%WVO 20%RUG blend.

Kind of popped my eyes.  I had never seen the RUG side that big.  And then I thought "1:8 is actually 12.5%" which seems to be a common number I run into on the street and web.  It's also what I use just before I pour the blend into what turns out to be a 1:3 (1 part blend and 2 parts B20).  Oh yeah, this is in a "DI" Isuzu NPR truck.

I'm always impressed when the heat is harvested that many operators throw away.  Being on the high pressure side makes even more sense.  Do you do any heating prior to the lift or injector pumps?

To be redundant - You do beautiful work.

Hey Casey,

I started experimenting with blending and running it in my '83 F250 IDI (15%RUG 80%WMO) . It ran well but smoked more than I liked. I experimented with blends up to 35% RUG (trying to match the viscosity of pump diesel) ended up at 20% to save money and it worked just as well. While I was burning the 5 barrels of WMO I got from some drag racer friends, I began to collect soy WVO. After running out of the WMO I made the switch. Even though WMO has more power, I read about the abrasive ash problems some were having and thought it wise to switch. There are now two gas stations on Maui selling ethanol free RUG and that is what I use. I also tried blending 1 gallon of acetone per 50 gallon batch but it really had a bad exhaust smell. (it's supposed to break down the animal fats in WVO)

Cole,
With a well heated system, and a start/stop on diesel, your IDI Ford should run just fine on 100% WVO.
I have a 1995 Chevy 6.5 Suburban with 221,000.  The last 35,000 were on 100% WVO, and your IDI 6.9 should be just as happy.

That high pressure line modification is awesome fabricator. I was thinking of something like that but never acted on it since I am currently running an 80%WVO 20%RUG blend. Do you preheat your fuel before starting?

-Cole

I run on bio until things heat up then switch to wvo, but my 65 gallon tank of wvo is in the rafters above the engine in the hottest part of the shed, so it's about 80-100 degrees before it enters the IP.

I use acetone in my bio, basically is affects the surface tension causing it to have finer droplets in the spray pattern.
