<http://www.ameriburn.org/Preven/Educator's%20Guide.pdf> is a nice
document describing the different properties of different fuels. I quote 
some from it that seems relevant:

The flash point is the minimum temperature at which the liquid will give
off sufficient vapor to form an ignitable mixture with air. Gasoline is
very dangerous because of its low flash point of –45ºF (- 43C).

Substance       Classification*                 Flash Point     Vapor Density**
Gasoline        Flammable Liquid                -45o F.         3-4
Propane         Flammable Liquid                -156o F.        1.56 @ 32o F.
Ethanol         Flammable Liquid                55o F.          1.6
Methanol        Flammable Liquid                52o F.          1.1
Turpentine      Flammable Liquid                95o F           4.8
Kerosene        Combustible Liquid              100o F.         4.5
Diesel          Fuel Combustible Liquid         125o F.         >1
Safety Solvent  Combustible Liquid              100-140o F.     4.8
Paint Thinner   Combustible Liquid              105o F.         4.9

As can be seen here, you basically have to warm diesel to 125F before it
will burn, gasoline will immediately burn/explode at almost any
temperature seen on any habitable part of the earth.

I believe kerosene is aircraft fuel, and as someone said here it's not 
that different from diesel.
