WILL MYSTERY ENGINE RUN 300 MILES
ON A GALLON OF OIL
From Popular Science, August 1922
Three hundred miles on a gallon of oil—10 times the mileage possible for
the usual present-day motor!
Such is the astounding record claimed for a crude-oil engine developed
by Harry H. Elmer, of Syracuse, NY, for use in automobiles, airplanes,
ships, and lighting systems. In experiments, the engine has generated sufficient
power to run a battery of 18 incandescent lamps 18 consecutive
hours on 1 1/4 pints of oil, costing less than a cent.
Because this mechanical marvel does not require a cooling system,
government officials, it is reported, are studying the possibility of its use
in dirigibles.
Among more than 300 radically new features claimed for the engine,
the most important are these:
It contains only 64 parts and has only three adjustments.
It has no spark, carburetor, wiring, nor any sort of ignition.
The cylinder has a bore [interior diameter] of 3 1/4 inches and a six-inch
stroke, yet the engine, it is said, has developed 200 percent more power
than internal combustion engines of the same size, and will pick up almost
instantaneously from 100 to 2800 revolutions a minute.
How the Motor Operates
The new engine is described as a four-cycle motor, the cycles being suction,
compression, expansion, and exhaust. The crude oil is led through
needle valves into [the] mechanism, where it mixes with air and then,
through another valve of the same kind, is drawn into the motor head,
where it is compressed by the upward stroke of the piston. On compression
the oil is "cracked" by chemical process and the expansion of gases
