Some modern diesels can be adapted to run successfully on Straight Vegetable Oil "SVO", that is either new oil or cleaned Waste Vegetable Oil "WVO". www.elsbett.com
Both biodiesel and SVO are known to scour petrodiesel deposits from fuel systems which can plug
up filters quickly until the system is cleaned out.
Biodiesel is only as good as the process that made it, some is ASTM grade and some is rubbish. I've seen some filthy muck come out of the bottom of gas station diesel tanks
when they run low too.
Most WVO/SVO vehicles use a dual tank system: start on petro/ULSD, switch over when the engine
is hot and switch back some minutes before shut down to purge the system of WVO/SVO. Most have heated tanks
and filters for the WVO/SVO, usually heated by the engine coolant
, sometimes by electric heating
, or both.
Considering what a PITA cleaning
out fixed tanks is, large cleanouts and even a heavy glass "viewing port" wouldn't be a bad idea. Have an illumination port too if you really want to get clever.
The best thing about B100 other than the vastly better lubricity is the lack of that bloody benzene stink that takes forever go away when diesel spills or leaks
. It also seems to rejuvenate the seals
in some older injection pumps which were never built for the dryness of ULSD; that stuff has caused the failure of hundreds of thousands of pumps. Tough thing to have happen in the middle of nowhere.
Worth having a small centrifuge on board to clean your fuel, and your engine oil; it's what the commercial
ships do. They can be driven off oil pressure to clean the lube oil, or compressed air or electricity to clean the fuel. Spinner IIģ Products : High-efficiency lube oil filtration for heavy-duty diesel engines.
If I were setting it up I think I'd have a separate locker with a watertight floor and door (at chest height) and separate ventilation and mount the centrifuge in that - they're messy to clean out, but you'll never run out of filter elements.
"Black diesel" is a story for another day.
