Posted: Mon Jan 11, 2010 23:59 Post subject: christmas is over...right il try again... |
|
|
as in my previous topics.....i tried blending 95% wvo and 5% rug and it worked for a few weeks (bad starting in mornings and a lot of power loss on hills)..then i broke down and it turned out to be 2 holes in the fuel pipes on the top of the tank dragging air in and causing fuel starvation, now we are all back to normal and xmas is over and im ready to try again .
ive changed the fuel system slightly...ive replace the complete fuel pipe with suitable for petrol, rubber pipe , ive bypassed the standard fuel filter and put an inline instead but thats all, ive got a j reg 2.5td pajero lwb its got 69000 on the clock and to be honest is bloody amazing,on normal dino it starts in the morning very well and never misses a beat all day, even in 700 mile round trips which i do a few times a year (fishing) visiting family etc etc.....but i want to run on blend and my car seemed to suffer a bit on blend so what can i do..
need some good advise please, ive read that seals and rubbers are at risk, so which rubbers / seals do i need to change to insure i can run on wvo blend .....and some ideas on heated fuel sysems, heated tank systems or modifications required.....i dont really want to do a 2 tank convertion because i need all my bootspace for my camping and fishing gear but if anyone has any ideas on that please throw your ideas ideas my way.......ive been toying with the idea to get a landrover 110 (stop laughing, i need the bootspace )and converting into a 2 tank setup but i prefer my pajero to br honest because even tho i have a welder i dont want to be welding a bloody landrover for the rest of my life and im a biggish lad and i need to travel is comfort and im pretty sure my paj is a bit more refined than a 1980 landrover....so please save me from myself  |

If you are considering a 2 tank system, use 2 filters [1 for each tank ]
You need to find a VW Kombi Petrol tank , the measurements are approx L 91cm X W 29cm X H 18cm
This size will fit under the floor on the L/H side on a LWB Pajero [ opposite the muffler ]
You need to dent the corner to clear the existing fuel lines, and get a Radiator Guy to shift the filler neck [ soldering required ] to fill in front of the L/H rear wheel arch above the chassis rail
at 18cm high it won't effect your ground clearance when mounted under the floor.
While on the hunt for VW bits, try and find a Water Cooled Oil Cooler, these neat little units sandwich between the oil filter and are easily adapted to the fuel filter [ as a heat exchanger ]
If you are looking at a Pollak 6 port valve [ which can cause problems ], note that the Pollak is a reproduction part. The genuine article is made by AC Delco for twin tank C10 chevy trucks and they seldom cause problems [ they are cheap in the States from wreckers ]
To run oil, you need Heat [ I can't comment about WVO ] , I am a believer in WMO probably because in NZ the shops now sell WVO but WMO is free.
WMO is compatible with all seals and all petroleum products used to blend, have you tried adding Xylol [ or Xylene ] to your WVO blend
Xylol is a light fraction aromatic that has similar properties to Acetone [ but is cheaper ] |

the underslung tank is a great idea ...have you done this yourself?..have you any pictures of the how the filler neck on the 2nd tank is situated..and how it looks?
something i know nothing about is a heat exchangers, do you have a heated tank and line or is there a specific place?
does the pollak style valve system self purge the lines or is heat the key? |

any ideas on blending?....am i right in saying that the powerloss when running wvo is due to cetane loss by adding petrol / acetone...?
is there a better way? |

Hi mark
One thing you will knead it a FPH flat plate heater.
Or a tube in tube heater.
This should be put before the filter to help melt any fats that have not been taken out of the oil.
Boy scout motto Be prepaid always carry a spare filter and know how to change it.

cheers bob ..do you have any specific makes or is it something i could make.?
..as for being prepered ( im like the boy scout from hell, i have a stove in the car with food and tea and coffee spare clothes , firewood and cotton wool balls soaked in vasaline for kindling ) ive got spare inline filters already in the car and it takes me less than 2 mins to change ,ive also put a non return valve on the fueline so i can bleed easily...imnot a mechanic but with a little help here and there il try to do most things i can myself on my car and i do like the idea of a underslung tank...is this what you have ...please tell me how you have set your system |

Cetane number is actually a measure of a fuel's ignition delay; the time period between the start of injection and start of combustion (ignition) of the fuel. higher cetane fuels will have shorter ignition delay periods than lower cetane fuels
The opposite is Octane rating which is a measure of the resistance of petrol and other fuels to auto-ignition in spark ignition engines
The difference between ambient temperature and ignition temperature play a role here, the higher ambient temperature the lower the cetane required [ an overheating petrol engine will also detonate easily ]
If you increase the ambient temperature of the fuel to closer to ignition temperature it will perform better [ hence the heat exchangers ]
Bob is correct "get some heat into your fuel"
Your powerloss when running WVO is due to the BTU [ energy ] content being less, when you thin WVO with a lighter fraction hydrocarbon you aggravate this problem.
Bio or VO will never have the same performance [either power / or economy] as Diesel because it has a lower energy value.
You can recover some power by 'turning up the juice' , but the economy suffers.
In a diesel , if there is a fuel restriction the power usually goes down [ in petrol engines , they cough and splutter ] ,so it will always be down on power if the fuel lines and filters are a restriction to "cold" WVO
The Pollak Valve is a 6-way valve. Actually it is 2 x 3-way valves parallel [ 2 x "Y"circuits ]
It has an electric motor that moves the plungers from one circuit to another [ that is the only time it is drawing electricity ]
So you can have 2 tanks feeding to the IP through the valve and the IP returning to either of the two tanks.
The electric motor that moves the plungers has been known to fail but they never leak [ you end up being stuck on one circuit ]
The Pollak also has provision to switch fuel tank senders to a common fuel guage at the same time.
The are a simple fix in one neat little unit [ Beware of some fakes around ]
I am in the process of doing the VW Kombi underslung tank , I am getting a Pajero Fuel sender and pick-up mounted in the tank right now. [ I'll keep you all informed ] |

Excellent. Looking forward to finding out more! By VW Kombi do you mean VW T1 or T2 Campervan? |

couple years ago i used wvo(from chinese take-away best) & drove through france & didnt clock fuel usage stupidly but noticed massive increase in area covered compared to using diesel otw home.
added it into tank on autoroute stops & engine being warm + mixing it with diesel- bout 50% each drove perfect apart from a little less power on hills
i think i pushed it too far tho, even tho it was in summer the morning being cold mixed bout 80% wvo with 20% diesel & she wouldnt start for me. had a local garage guy drain it & all he did was mix the wvo + diesel together & put it back in & i was driving fine again. havent used wvo in a while but thinkin bout starting again, after a few adjustments on the paj first tho |

I'm using a 1967 Kombi Tank [ I wrote the measurements on an earlier post ] The fuel tank should be the only thing left on these old buses that hasn't rusted out.
Just find an Aussie or Kiwi tourist and swap their Kombi for a crate of "fosters" or "lion red" |

Cheaper ones are available you just have to look.

Try replacing the filter
And fill the filter with white diesel
See if this will start it
Let us know how you get on

| Totally agree with Bob, could easily be a blocked filter |
