THIS paper describes what the authors consider to be a simplified method of determining the vapor-locking tendencies of gasolines.The study of vapor lock was undertaken after they found the Reid vapor pressure method to be inadequate. The result of their work was the development of the General Motors vapor pressure, a single number which predicts vapor-locking tendency.The authors point out the following advantages of the new method: It allows direct comparisons of vapor-lock test results of different reference fuel systems; establishes distribution curves of volatility requirements of cars for vapor-lock free operation and of vapor-locking tendencies of gasolines; is a common reference value for both petroleum and automotive engineers. Finally, it more realistically evaluates the effects of small weathering losses on vapor-locking tendency than does Rvp.THIS paper describes what the authors consider to be a simplified method of determining the vapor-locking tendencies of gasolines.The study of vapor lock was undertaken after they found the Reid vapor pressure method to be inadequate.
