KEROSENE POWER
USED FOR TRUCK
DuntIey Device Demonstrated
Successfully With Little
Giant in Washington.

A device to use kerosene in motor
trucks and pleasure cars has been in
vented by John w. Duntley, OF Chi
cago. Duntley has called 1t the
Hydro Pneumatic Gas Generator, and,
used with a tank mixture of half
gasolene and half kerosene, It is said
to handle the oil with perfect COM
bustion, virtually eliminating carbon
deposit and gaseous odor and smoke
vapor.
At the local salesrooms, All Mis-
| souri, avenue. a Little Giant two-ton
truck is equipped with the device, and
every test of regular service has been
made with success. The device seems
to be the solution of the problem of
how to use kerosene effectively in a
combustion engine.
1t is said OF the Duntley product
that "the motor operates on a super
heated hydrogen and carbon-monoxide
gas OF unknown actual chemical
analysis.
Very High Heat Units.
"The mixture. however. Is known
beyond doubt to possess very high
heat units, which increases the power
Of the motor from 10 per cent to Is
per cent, depending upon the condi-
tion OF the motor. No vaporized fuel
enters the cylinders. and in conse-
Quence there is nothing to carbonize
or to work past the piston rings and
deteriorate the lubricating oil in the
crank case. 1t will be appreciated
by motorists or owners OF trucks,
there will be less bearing troubles
and the absence OF carbon insures
perfect seating OF the valves.
THE valves will rarely require
grinding in, except at long intervals.
Rings, wrist pins. and bearings have
heightened life, and motor repairs are
reduced to a minimum.
THE motor runs cooler and spark
plugs maintain clean and bright
firing points, which rarely ever re-
Quire attention unless a piston ring
should break and allow lubricating
oil to pass by and into the combus-
tion chamber.
THE power OF the motor IL In
creased from the fact this new gas
Goes not suddenly explode, but burns
and expands behind the piston for its
full length OF travel, OF, In other
words, duplicates the action OF steam.
IL is impossible by any knew n methol
OF rnaneuverinE to make the motor

so common in motors using Vaporized |
fuel.
THE increased mileage to the gal |
Ion of fuel is due to the fact a finer |
adjustment OF the fuel needle-vaIve Ia |
necessary, thus reducing the quantity |
OF fuel vaporized through carburetor. |

becomes, through unique mechanical
OF the generator, a su-
perheated dry steam.
Chemical Makeup Unknown.
''The carbon in the superheated fuel
having an affinity for steam is in
stantly absorbed by the superheated
steam, and the whole Is transformed
Into high temperature hydrogen gas
Chemists will appreciate the impossi-
bility of an analysis at the tempera-
ture at which the gas enters the ex-
plosive chamber and is exploded, and
In consequence its true. chemical
may never be known defi-
nitely.
