Extract

This paper is an endeavour to present, to the members of this Society and others, as complete information as possible on the subject of a much discussed anti-knock material and to try and dispel any misconceptions which some may still have regarding the use and behaviour of ethyl.

The development of the modern aviation engine has made rapid strides during the last two or three years. The very rapidity of this development, however, has brought an exceedingly important fact home to the engine manufacturers; this is, the influence of the fuel in governing engine performance and reliability.
