“In the early 1900’s, Dr. Edward A. Rumely, grandson of Meinrad [Rumely], was determined to build a tractor that could run on a wide range of fuels. He hired an engine designer by the name of John Secor to work with Rumely’s plant superintendent, William Higgins, to design such a tractor.
“The Secor-Higgins design involved an engine that was of higher compression than was standard at the time. It was cooled by oil, which served the dual purpose of allowing the engine to run hotter to utilize the heavier fuels and to avoid freezing in cold weather. The Secor-Higgins carburetor not only atomized fuel into the incoming charge of air, but water as well. The water prevented preignition when the engine was run under heavy loads.”
I only wonder, if you could just get it to thin enough to start atomizing through the carburator, whether a guy could burn lard and bacon grease? The way I understand it, the blast-pipe and exhaust action was used to heat the fuel in a pass-through chamber so that it would carburate. Water (condensed exhaust steam?) seemingly was mixed in to prevent knocking…. Actually, the way things are now, I bet you could probably burn Mankato, MN, river-water at least for awhile in the Spring, after the boys get done spraying everything the bill-of-goods agchem companies have to sell them, onto their fields and into the runoff water!
The Advance-Rumely concept is interesting just because there is even more crap everywhere now that could be burned in these moe-sheens (Heaven help the air!) and sooo…HERE is a link that tells more about it:
