Summary:

RADIOACTIVE TRACERS have been used to study the fuel distribution among individual cylinders in two modern V-8 engines. Individual fuel components (both hydrocarbons and fuel additives) were "tagged" with radioactive hydrogen (tritium) or carbon-14. These "tagged" components were blended into a commercial-type fuel, and their distribution to engine cylinders was determined by measurements of exhaust-gas radioactivity. The quantity of fuel distributed to the cylinders was measured by an exhaust-gas analyzer of the catalytic-cell type.The results reported include the effect of various fuel factors, operating factors, and engine design factors on the distribution of both whole fuel and its components. A study of octane placement within the boiling range of the fuel revealed differences among fuels when rated under accelerating conditions (with "manifold lag") and when rated at constant-speed conditions with poor fuel distribution.Also discussed briefly are the improvements in engine power, economy, octane requirement, and fuel ratings which resulted from improved fuel and tel distribution obtained with a modified carburetor
