Government expert listens to broadcasts of automobile ... The Automotive Section of the Bureau of Standards is studying the anti-knock proportion of fuel used in automobile and aircraft engines and the scientist in this photograph is "listening in" to the signals of an engine instead of listening to a radio broadcasting station. Eventually, these studies may evolve a new engine, one that will use fuel more economically and efficiently
Substitute fuels tested. Conducting an experiment to determine whether engine wear is increased by the use of fuel substitutes, Emmet L. Reed of Washington, D.C. makes an identification mark on the cylinder of an automobile engine. The rate of the mark's disappearance will determine the degree of wear. This is part of the "ersatz" fuel experiments which are being conducted at the U.S. Bureau of Standards

The stickers will be issued with the new coupon books and must be displayed on the automobile
Rating gasolines at the Bureau of Standards. Washington, D.C., April 17. F.R. Carter of the U.S. Bureau of Standards is shown adjusting the mixture of gasoline to find out the rating in octane numbers of gasolines. The three carbureter shown in the foreground are each filled with a gasoline tow of which with a known octane rating and the third is filled with the sample to be tested, this machine has a variable compression ratio and can be changed while in motion
Auto conversion to airplane engines. "We'll be turning out as many airplane engines as Carter does pills," employees of a converted automobile factory told OEM (Office of Emergency Management) photographer. Now undergoing one hundred percent conversion to airplane motor production, this factory employs thousands of workers who are familiarizing themselves with the newly installed tools and machines. A worker here operates a vertical Bullard turtle lathe, machining part of the aluminum crank case of a fourteen-cylinder airplane engine. Chevrolet, Buffalo, New York
