WVO single tank . what % this time of year

[rezdiver]

whats everyone running this time of year for their mix? and what is your local area outside temperatures for your blend?

[jessef]

I don't blend below zero.

Above +1 to 10ish (winter) I'll blend 50L diesel / 20L wvo with 50ml 2stroke oil.

Above +15 (summer) I'll blend 35L diesel / 35L wvo with 50ml 2stroke oil.

This is with L400. With L300 I blend more diesel.

[rezdiver]

why the different blend between the 300 and 400? do they have a different injection pump? they are both IDI motors right? still learning.

[jessef]

WVO varies from vehicle to vehicle. My experience (I go through these like candy and love it), my L400's enjoyed a higher wvo blend than the two L300's in pure stock form. Too many variables to make a scientific estimate.

[rezdiver]

with your mixes are we talking stock form no mods or with any type of preheater or extras added?

[jessef]

no mods, bone stock but all had very healthy fuel system's. rebuilt IP, injectors and on the L300 is had relined fuel tank and new fuel lines.

unless you have a top notch engine/fuel delivery system, I would not blend that high.

[Luna-Sea]

do they have a different injection pump? they are both IDI motors right?

Same type of injection pump (rotary)
Both Indirect Injection Diesels in L300/L400 yes.

Right On!

I'd mix a bit less than Jfarsang suggested. Comes winter time I'd stay around 5-10% max. It will take more but from the research I've read for engine longevity it was 25% max in warmer months and none to 10% in colder months. You'll know you've pushed too far when starting your van in the morning is more difficult and produce more white smoke... but that might be way above ideal numbers once you get those symptoms...

Good luck!

[rezdiver]

wow, not too many single tank setups here.

[delicat]

Nope, just a bunch of people mixing some veggie in a stock van... Works fine in the summer and it's even a good idea as it lubricates the seals and compensate for the low sulphur diesel but comes winter I'd personally wouldn't bother...

Cheers,
Mr. D

For Jan the low temps are moving up in the fraser valley/lower mainland area. Good time to start blending more wvo or svo.

If you're into single tank systems, the Elsbett one is the holy grail of them all.

Loki bought and installed a single tank Elsbett system in his L300 2.5.

It was working well the last I heard.

well i have been messing around with my mixes on my single tank in my volkswagen turbo diesel. this has the same style bosche injector pump as the delicas.
-heated fuel line from tank to filter
-heated injector lines
-coolant heated fuel filter once the engine warms up then i shut the power down to the electric line heaters.
-manual glow plug control, usually cycle for 2 minutes for a good start up in the morning, less than 1 minute during the day.

these VW bosche glow plugs are indestructable, i have left mine on repeatedly for over an hour at a time by accident and they never burned out, even after a year of abuse.

so far down to -11 i have had very good results with 65%wvo, 5-10% RUG, 30% diesel. started everytime, a lot more injector clacking which went away once warmed up.

i tried to bump it up to 75%wvo 25% diesel and she would not start below zero.

two areas that need to be worked on that will guarantee startups in the cold with a thick mix, i need to heat the filter and i need to heat the whole injection pump itself. I am making a heater setup using 12v/50watt halogen light bulbs to be able to heat the pump and filter. i looked at specific heaters and found its a waste of money when a couple 50 cent light bulb will do the same thing. halogen bulbs emit over 80% of their energy as heat so they are pretty efficient as a heat source.

i will be building a bracket that will aim a bulb at the filter, one at the injection pump and possibly a couple aimed at the top of the injectors. this should be more than enough to preheat everything for cold mornings and thicker mixes and way cheaper than using heated resistive lines.

[jessef]

If it's that cold, will the heat from the lamp warm up the ip quickly enough without drawing a lot of battery juice?

Since you're mixing with diesel and have access to diesel, why not use a small 5L canister/jug as a starting/purging container with 100% diesel? This way you would forego the heating lamps and additional draw on your electrical system and be able to start in any condition within reason up to -30/40.

You're taking a different approach which is good to see.

[rezdiver]

the heat from the lamp is plenty even in very cold weather, the only factor is how long you let it stay on and how close you mount it depending on outside temps. draw from the batteries is not so much an issue, its the same as leaving your headlights on for 5 minutes. easy enough to rig up a second battery for extra draws if needed. the draw would probably be the same or less than resistive line heater wire. guess the only way to find out the effectiveness is to try it out.

adding a purge container to purge with diesel is going backwards to a two tank system, if i want to hook up all the solenoids and valves to be able to purge the system, may as well just hook up a second tank. if i was in alberta i would go two tank.

this is all just a trial and error to see how my engine holds out.

[jessef]

looking forward to your results. I'm assuming the IP and nozzles would fail long before the engine so that's a plus.
