              Stick at it, Sister! For the first part is often
hardest — you have to thread that needle
before you can sew a fine seam. It's like a
job we had to do on an engine once. When
we got it done, the engine helped lighten the
world's work and fight the war — all at the
same time.
SOME 25 years ago, General Motors engineers set out to make a better Diesel
engine. They found they could — if an im
portant part could be improved and made
quickly in great quantities.
This part, which the engineers call an injector, works like an atomizer. It breaks up the
fuel oil into a fine spray by forcing it through
a hole many times smaller than the eye of
Sister's needle. Injectors had always been
made by hand — a slow, costly process.
It took a long time — years, in fact —
but General Motors men finally worked out
a way to make better injectors and produce
them by ordinary production methods. And
their research brought many other improvements.
AVesult: a Diesel engine that was more compact, lighter in weight, and so dependable
that it was soon humming away at all sorts
of tough jobs. Today it is at work in rail
transportation, road building, heavy hauling, and many other important tasks.
When war came, GM Diesels proved a
"natural" for many uses. Singly or teamed
together as "Twins" and "Quads," they now
power tanks, bulldozers, landing boats,
submarines, subchasers, tugs, generators.
Engineering like this is giving us things
needed in war just as it gave us useful things
in peace. Today it is more active and creative
than ever. It is a great energizing factor in
our American system. And it is ready to help
give us "more and better things for more
people" when final victory has been won.
