The committee then inquired into the status of the development and availability of control devices for automotive engines and the problems associated with the increasing use of gasoline additives.

Because of the rapid increase just then in number of cars in use and the consequent need to make more gasoline out of each barrel of crude oil refined, gasoline became less vola tile and at the same time worse in degree of freedom from knock.

But the successful survivors had gasoline engines which employed the Otto principle.

It is the purpose of this statement to present and, so far as possible, to document the salient facts concerning the hygienic aspects of the occurrence and distribution of lead in the environment of citizens of the United States of America, with particular reference to the contribution made by the use of leaded gasoline.

The straight-run, thermal-cracked, catalyticcracked, polymerized, and natural gasoline are blended together in a continuous automatic 10 blending system where tetra-ethyl lead is added to giye a finished motor fuel, meeting vapor pressure, distillation, and octane specifications.

It was feared that this property, which could be expected to contribute significantly to the rate and extent of the vaporization of the lead compound out of commercial gasoline, might create an uncontrollable hazard for the handlers and users of leaded gasoline.

The committee further finds that heavy pressures from ' the West Coast area and the high profit reward for achievement are strong motivating forces toward ultimate success in this field. 3* Gasoline Additives Gasoline additives are generally known as anti-knock compounds such as tetraethyl lead, and anti-oxidant com pounds such as phosphorus and
