THE VAPORIZING OF PARAFFIN
FOR
HIGH-SPEED MOTORS
(ELECTRIC IGNITION TYPE).
CHAPTER I.
INTRODUCTORY REMARKS.
In the successful use of a flash-proof fuel, such as any
of the burning-oils known as “ paraffin/’ there are many
difficulties not experienced with the use of petrol or gas,
especially for running motors of the high-speed electric
ignition type; for a liquid fuel not vaporizing freely at
ordinary temperatures is so different from that of
gaseous, being composed * of an almost unending series
of gradations. Thus, although crude petroleum in the
main is only separated into a few principal grades by
the process of refining, such as the benzine and paraffin
series, intermediate and residual or fuel-oil grades, these
again vary in themselves almost indefinitely, according
to the origin of the raw material and to the particular
method adopted in separating out the various con-
stituents. For instance, no grade, light or heavy, is of
regular composition as water is, but is compounded
of a blend of different densities and flash-points; for
this reason the refining process can and is modified to a
* The reader should refer to “ Oil Fuel, its Supply, Composition, and
Application” for further information on this subject.
