With the tremendous increase in the
consumption OF gasoline and the con-
sequent reduction In Its quality, the
fuel problem Is becoming of greater
Importance every day to the automo-
bile owner.
To understand the situation 1t is
necessary to remember that the auto
mobile motor is operated by heat, that
1t Is the expansion of the hot gases
in the combustion chamber that moves
the piston. The problem then is TO ex-
tract as many heat units as possible
out of the fuel that is taken into this
cylinder.
In the early days this was compar-
atiyely easy as the gasoline supplied
then was highly volatile and was cas-
lily vaporized into an inflammable. gas.
Al the demand for gasoline Increased.
however. the supply proved insuffi-
cient and had to be supplemented by
the addition of heavier oil products
which were not so easily vaporized.
The result was exactly the same as

motor To remedy these evils, engi-
neers resorted to various methods OF
applying heat to assist in the yapor-
izing of the fuel, realizing that the low
grade gasoline available would supply
more heat units than high-grade fuel
and furnish more power IL these heat
units could be extracted.
