Hello Greg,

I fear that this discussion is fragmenting into some rather odd directions, off course from Andy’s intent to find an etherless diesel fuel. My use of Energy Density was to help other see that various fuels do contain more or less energy and also have other characteristics such as viscosity, Cetane rating, and yes as you pointed out various mass densities. I’m not trying to pretend to be a Science Teacher, just encourage others to mix up various mixtures of safe and sane readily available common fuels and oils.

This thread could quickly degrade into a mash of odd physics debates, which are of little interest to me. I’m only interested in encouraging others continue on your happy course of a good simple “No Ether Fuel”.

Yes, I did see your test result. Very nice work and thank you for experimentation posting.

I don’t know the answer to your questions. I’m not a chemical engineer.

Yes, cold starting appear the problems. Take a look at this like: http://www.dstarengineering.com/news...tors_main.html

D-Star has a little generator set that is only about 5 inches square that put out about 50 watts. It runs on JP-8. I spent a great deal of time digging around on the Internet and found that it uses just a bit of oil added to the fuel. It also has a 1- minute preheat cycle for startup using some sort of resistive heater. I found this information about 1 year ago and passed it on to Andy. Andy called D-Star and talked to the owner.

It was this device that peaked my interest in a “no ether fuel” and I suggested to Andy the use of some sort of Hot Spot within the engine. Andy did test this feature and posted it on RCU. Do a search for Hot Spot.

I did not know about the other diesel system with an air valve, many thanks for that info.

Again, can we please get back to find a “no ether diesel fuel. I apologize for not using exacting descriptions.

I’m done,

Kelly
