Hi Treven,
Damned metric system, not my forte, too old. [:@] Sorry, your right, I got the two intertwined. [&o]
From here,

The above link was just found and has some more, in depth, information.
They use Kelvin, but that's not where I got my info. Every time I punch in the search for one fuel or the other, I got different sources and some worked in Celsius and some in Fahrenheit. Stupid of me not to notice. [

From the link,
Kero, 226C 440F 500K
Gas 376C 710F 650K
Naphtha 550C 1022F 832K
Ether 176C 350F 450K
I messed it up pretty badly. The site above doesn't cover naphtha so I took your figure and converted.
But here,
http://www.osha.gov/SLTC/healthguide...cognition.html
Naphtha is given an AI temperature of 277C ???
But this is COAL TAR Naphtha. What's the difference between that and plain Naphtha?
From OSHA again,
http://www.osha.gov/SLTC/healthguide...cognition.html
This is VM & P Naphtha, Varnish Makers and Printers Naphtha
AI listed as 288C
But from here,
http://www.intox.org/databank/docume...tha/cie806.htm
We have a high flash point naphtha, likely what we're talking about with an AI of 471C
So it looks like I took the first reference I found and used that in my post, along with not noticing the scale,,,,,
The Internet, like any other tool, can be useful but also dangerous as well.
But notice that there are Naphthas that have an AI similar to kerosene. So what? Don't know, but what if that form of Naphtha was tried without ether and we'd have a no ether formula that didn't have throttling issues? Or maybe these Naphthas might be used together with kerosene to give us a blend of useful properties.
Yesterday I picked up a jug of Bardhall additive that is made to revive worn out engines. Helps to seal leaky valves and piston rings. This is a petroleum product and pours, or rather globs, out of the jug far more slowly than even molasses. I added some kero to it and it blended. Then I added some castor, (Benol) and that blended nicely. So I made up a mix by adding the two oils first and then the kero in a 1/3rd ratio. No matter how much I shake it, no blend.
The jug mentioned some kind of polar characteristic and so on speculation that it might behave a little like a vegetable lube, I thought I'd give it a try. Being so thick, maybe only 5% might be needed and we might get a bit more of that power ingredient we want.
About castor. I had a link yesterday, (saved it, can't find it now) that re-affirmed what you're saying about veggie oil as lube. Still, it was interesting trying.
But I'm thinking that with the reduced RPM of diesel, the oil we might use will not be under such stress in that way. Yes, the loads are greater but maybe no matter, for some reason. With the Norvels, on diesel, it appears that the only thing you can hurt is the rod. I haven't given up though. I'm going to do my best to break something else. That hollow wristpin is a likely candidate. [X(]
No rain today but bitterly cold with strong winds. Maybe tomorrow.
