May 1989 issue of AUTOMOBILE MAGAZINE's BASIC TECH,by Barry Winfield,page 42-43 gets into the water emulsion.
"Household detergents in concentrations of 0.25 to 1.0 percent of the fuel volume make a satisfactory emulsion."
"Testing has confirmed reductions of nitrogen oxide concentration by 90 to 95 percent in exhaust gas; at 50 percent water in emulsion,there is practically total elimination of nitrogen oxide.Carbon monoxide is reduced by about 60 percent."
"An engine with a high 12:1 compression ratio was put on a test stand,operating on high-test aviation fuel.Even so,knocking was not quite absent.The engine was set to 3,000 rpm.When a fuel emulsion of 90 octane gasoline with 30 percent water was substituted ,the engine speed increased to 3,600 rpm,a 20 percent increase in efficiency,while exhaust temperature increased from 1,400 to 1,600 degrees Fahrenheit,indicating improved combustion of hydrocarbons and carbon monoxide.There was no trace of knocking."
A Ford Falcon was operated on a 50/50 emulsion of 50-octane gasoline for 1,000 miles without a major mishap.
This procedure is applicable to Diesel and stationary powerplants,too.
It looks like the premise is octane enhancement.There is no mention specifically of mpg benefit.
