Andy, thank you for your generous offer on the fuel. It seems that you are still sorting out the mix so when you have it figured out send me a PM and we'll talk about it.

There are very good logical explanantions why a large slow running injected diesel can burn virtually any oil. The main two reasons: the atomization due to the fuel injector and the in cylinder compression temperatures. Guys have been running Mercedes 300Ds and other vehicles on SVO and WVO before biodiesel became common. With some basic changes to the fuel system the diesel engines will run on veggie oils.

The FIRST thing I did last year when I started the FS conversions when I had problems random guessing proper compression ratios was research. The first topic was diesel (compression ignition) combustion theory. All of my tests this year have only verified what I have learned through research. I said it before and I'll say it again, I haven't broken any new ground. I've applied it to model engines is all.

Ken, I see a lot of ambition. I see applications for such an engine also. The D-Star generators can be that small only because they run at High RPM. The .54 runs at 14,000 RPM and makes 1.3HP. There is simply no way to build a naturally aspirated of that size to run half the speed with the same horsepower.

Andy and Ken, and anyone else for that matter. How do you intend to vaporize an oil so it can burn? Heating things sounds like a good idea, but what is really happening when you do this? The fuel won't provide any substantial cooling for the engine, unless you are pumping it back to the tank with a radiator in between somewere to get rid of the heat. This is actually done in some airplanes with wing tanks and heat exchangers between the engine coolant and fuel system.

I have run a lot of etherless blend in the four strokes. Well not a lot because it runs for so long. I've also run synthetic lube in brand new engines much to the dismay of everyone here. I even got a two stroke engine to run for a bit with a castor/gasoline mix. Was it great? No. Did I get excited? No. Does it warrant further investigation? Probably not, based on my research into the subject and the results I saw, which again proved that the existing information on the topic was valid. Not practical for a simple model engine anyway. Will I try again? Probably, just to see if there are any possibilities. It will need a different engine.

So many ideas so little time.
