OCCURRENCE OF VAPOR LOCK AS RELATED TO THE Temperature- V/L Characteristics of Motor Gasolines

REPORTED here are the methods of applying the temperature - V/L relationships to the analysis of data resulting from actual vapor-lock tests. Particular consideration is given:

1. 1.
   To evaluating a fuel system in terms of the fuel of highest volatility on which it will operate under specified conditions.
2. 2.
   To establishing a satisfactory specification for fuels having distillation and vapor-pressure characteristics different from the fuels employed in the vapor-lock tests.
3. 3.
   To determining what conclusions can be derived from different items of test data.
