Vegetable Oil SVO WVO waste cooking oil as biofuel

[Halitosis]

Title about says it all.

I converted the X in July of 2006. Installed the Vegistroke when it was still in it's EARLY stages of development (back when he was still trying to get Mallory fuel pumps to behave, and jacking up the fuel pressur to something like 90+ to "overpower" the stock fuel pressure).

Have kept up with a few upgrades to the Vegistroke as Jason has come out with better designs... more notably the HIH system (which is a WINNER design, and worth every penny), and the newer FASS pump for the Vegistroke. (Another winner).

You'd really like the V3, plug and play FASS pump, built in inline filter before the pump, super fast switchover time.

As I mentioned to someone yesterday, the V1 and V2 were "how can we make this work" The V3 is the response to "how can we make this better".

Sam, how fast is your switchover if the engine has been off for 18 hour and at what outside air temperature at startup? Just curious how it compares...
Thanks,

Hi HOT,

I've probably got more data than you'll need. There are three factors, Warm up time, Driving time, Driving distance, (driving speed too, but I used the same routes so I didn't save that data).

Driving cold, no warm up time, at 40-50 degrees F, takes 3 to 4 miles to switchover.

Warmup to switchover (no driving) takes 18 minutes at 29 degrees F.

With an average warmup time of 10 minutes I have between 1 and 1 1/2 miles from 20 to 50 degrees F.

Best performance with least fuel works out to having at least a 9 minute warmup prior to driving.

Thanks Sam! Very informative...I like all that data! I normally don't spend any time warming up (parked is what I assume you mean). I just start up and drive off, unless there is snow that I have to clean off.
So 3-4 mi with 40-50 deg. ambient is what interests me most. I'm tweaking my setup in a quest for faster switchover times. I'm about to make another change. You've got me beat with my current setup by a mile. So I know I've got room for improvement. :/

I've got one question so I can compare your experience to mine (apples to apples comparison). Do you know if you switchover at 140 degF or a higher temp? If it is at 140, then we are comparing apples to apples and that beats my current setup, so I would say that is "superfast."

One caution for you. I wouldn't suggest warmup (no driving 18 min @ 29 degF) and allow the system to switchover automatically to VO mode. The reason is the cylinder doesn't get hot enough in a no-load situation (idling only) to support VO mode. Accumulations could occur and result in coking. We can monitor the VO temp, but we can't monitor the cylinder wall temp! Maybe I'm being overly cautious?

Nonetheless, if you switchover is at 140, you've got me beat for switchover time/distance.

Thanks!

My switchover is at 160 degrees. I don't think there is a chance that it would switch to vegoil before the engine is hot enough, and adding heat to the oil in the rails since by the time my oil is up to temp my engine is real hot. And with 52K on vegoil it doesn't miss a beat, starts quick runs smooth, the biggest problem I have is keeping it away from Jennifer long enough to drive it. Ummm I'd get to see her and the truck a lot more if I had gotten a smaller fuel tank.

Speaking of trucks...if anyone wants to buy a diesel truck this is the time to strike, you can hardly give them away. A friend of mine bought a 2006 Ford 6l with under 35K for 11 thousand.

Hope everyone is well, I haven't been reading many post lately.

I have the vegistroke v2 in my 2000 f350..

it had switch over a few times were the oil wasnt hot enough.. leading the engine to actually lose power until it shut off.

Probably not the vegistroke fault cuz the engine reached optimal temperature before the switch over, but rather that the in tank hotfox setup failed to heat the oil up that quick, i also had the filter heater on as well..

Those days were really cold at night (32f or less) but it was in 40'sf in the morning..

I just got e-mail notification that my V3 is on its way and should be here by Wednesday! Have any of you tried winter fronts or block heaters to shorten warm up times? I figure I'll have quick warm up times through August and the beginning of September but once October gets here that will be the test.

Good for you. I haven't tested blocking the radator, it will be interesting to know what you find. If I had to guess; you'd shave off maybe a mile of driving at 40 mph, which might be the most difference between winter and summer...but it would be good to know what you find.

I'm thinking of taking a two pronged approach-it makes no sense for the block heater to run all night, so I'll plug in via a light timer. I typically leave the house at 7:00 AM so if it kicks on around 4:00 AM I would imagine it would be adequate. I think the heater will bring the coolant to about 100 degrees, which is better than starting at whatever ambient is. That plus the winter front ought to save at least a mile or three?

You probably want a timer that can handle a heavier load than a light.

Yes I use a winter front that blocks either half or 90% of the front and it makes a huge difference in my switchover times, more than the block heater does and its simpler and consumes no power.

I use both during winter.

What are your switchover distances, at what outside temps and with a warm up, or not?

With the block heater and ambient around freezing it still takes almost 15 miles to get to 180*F coolant, the minimum before I flip tanks even with the winter front. Purge is always between 2-3 miles before shut off.

In summer I reach 180*F coolant in <5 miles, obviously w/o the block heater.

I'd love my 7.3L to heat up faster in winter, but such a large block of iron does take time...even with my 203*F t-stat and the winter front.
