You make a very good point. It would be usefull to know the optimum temperatures for several fuels. Diesel # 2, Biodiesel, and SVO/WVO. It would seem to me that as long as you did not start vaporizing the fuel in the lines or heat it to the point where it became a fire/saftey issue the hotter the better. Less viscosity at higher temperatures should make for better atomization. and the hotter the fuel the less heat energy it would need to pull out of the air in the combustion chamber to start burning and burn more completely. But, I am new to all of this so it's all just a SWAG on my part.

Best regards to all!
