RE: Substitute for Ether
Andy,
your efforts are appreciable, but I think possible to go too far with hope, sometimes. Make glycerin evaporate from a fuel is almost impossible, since the fuel will boil well before than glycerin. By heating strongly a fuel you can only evaporate methylic alchool and water. Maybe if you wash the fuel before heating you will separate the glycerin since it goes in solution with the water.
Preheating the fuel coming to the engine can be useful but it is only a faible remedy since it will not evaporate until the cranckase is not hotter than ebullition temperature of the fuel itself . This means that until the inner cranckase it is not about, say, 300°F you are actively working to wear the conrod, if you use straight kerosene or bio. And dont'mind fuel "lubricity", it is simply MEANINGLESS for HCCI engines since no injector is used.
