Mutual Adaptation of Aircraft Fuels and Engines

THE great increase during the last 20 years in the knowledge of fuel behavior in piston engines the author attributes largely to the use of full-scale engines for fuels testing and engine development work, the use of pure compounds as reference standards, and the standardizing of laboratory knock-test methods.

He sees preignition, fuel-air mixture distribution, and stability of stored fuels as engine-fuel problems which may have to be tackled in the next few years if development of the piston aircraft engine continues.

Mr. Heron presented this lecture after receiving the Horning Memorial Award for 1945.
