Gasoline and electricity have made possible the modern automobile.
Each has its work to do in the operation of the car, and if either
fails to perform its duties, the car cannot move. The action of the
gasoline, and the mechanisms that control it are comparatively simple,
and easily understood, because gasoline is something definite which we
can see and feel, and which can be weighed, or measured in gallons.
Electricity, on the other hand, is invisible, cannot be poured into
cans or tanks, has no odor, and, therefore, nobody knows just what it
is. We can only study the effects of electricity, and the wires,
coils, and similar apparatus in which it is present. It is for this
reason that an air of mystery surrounds electrical things, especially
to the man who has not made a special study of the subject.

Without electricity, there would be no gasoline engine, because
gasoline itself cannot cause the engine to operate. It is only when
the electrical spark explodes or "ignites" the mixture of gasoline and
air which has been drawn into the engine cylinders that the engine
develops power. Thus an electrical ignition system has always been an
essential part of every gasoline automobile.
