Al,
No, I meant the injection event. Not ignition event. I'll look for the paper.
Yeah, I've also read several long term studies of BD on engines. I'd like to see similar studies done with differing injection timing, and a D2 control engine. I'm really curious about cylinder bore wear (I know about the high BD lubricity) in the real world, and the effects of BD in engines which may allow some lube oil contamination (older rings).
I have also heard anecdotal evidence that the listers do not like WVO for long periods. Those engines are supposed to last an amazingly long time (at least the original British ones). Listers with shorter lifes could be due to WVO or possibly Indian quality control.

found it
linky to the document.
http://www.nrel.gov/docs/fy03osti/31462.pdf
Info on injector opening time (effective timing) with different fuels, as well as the related propagation of a pressure wave through an injector line.
In section 5 Viscosity of fuels is briefly discussed, but was not studied.

Thanks for the link; I'm pretty sure I skimmed through that one before, two years ago.
On page 5, the Abstract does say "injection timing" but I'm certain they are talking about the effective ignition point rather than the place in the cycle when the liquid is squirted out of the injector.
I admit that I am not spending any time tonight actually reading this thing: it's my bedtime, and I have a truck to scrap in the morning.
