biodiesel auto-ignition temperature?

Question

What is the auto-ignition temperature of biodiesel.
I really need it.

Answer 1

It should be pretty well the same as for ordinary diesel; but if it matters in a practical sense, check with the supplier.

Comment: Unless you are making your biodiesel from waste oil of some kind, you may well be making things worse, because of the energy input in growing the crops, and the competition between this kind of agriculture, growing food, and preserving natural environments. if biofuels are ever to do us much good, they will have to be derived from cellulose, so you can use the whole plant.
