Pre heater when using Bio Diesel
Options
I've been using Bio Diesel in my car (VW Bora TDI PD) for the past 6K miles.
Tend to go with a mix of about 45L Bio and 5L Fossil. Sometimes the full tank completely Bio.
The car runs fine and I don't want this thread to descend into weather Bio Diesel should be used or not. There's enough threads on that.
The car runs great on BioD though I can tell that there's a slight hesitancy when turning over on start-up.
I know this is due to the viscosity (and I have also changed the Fuel filter) of the BioD but was hoping I could fix this with some sort of pre heater.
There seems to be a lot of heat exchangers on eBay (some home-brew), but my understanding is that these can only heat the fuel once the engine is warm as it uses the coolant to heat the fuel. Kind of defeats the object for me as I want to heat the fuel on start-up, so (I'm guessing) it would have to be connected to the battery/glow plugs.
Anybody know what I should be looking for, in particular for my vehicle? Also, does it make a difference if it is installed before or after the fuel filter?

I have opinions, you have opinions. All of our opinions are valid whether they are based on fact or feeling. Respect other peoples opinions, stop forcing your opinions on other people and the world will be a happier place.0 -
A really good modification I've seen, is to fit a modified baby-bottle warmer to the fuel filter can. It'll run off 12v, I'll go and find a linky thing...:DC.R.A.P.R.O.L.L.Z # 40 spanner supervisor.No problem can withstand the assault of sustained thought.Only after the last tree has been cut down.

Possibly the quality of the bio?
Do you make it yourself or buy it from a company?0 -
I buy it from somebody. He doesn't make it himself but he buys it in bulk.scotsman4th wrote: »Possibly the quality of the bio?

Just by speaking to him you can tell he knows his stuff and I'm confident he get's quality stuff. He uses it in his own car.
It's a common symptom when you use any fuel other than Dino.0 -

Have you had this issue from when you first started using bio or is it a more recent thing?
If it's happened more recently, I'd check my glowplugs.0
