Standard Test Method for Vapor-Liquid Ratio Temperature Determination of Fuels (Evacuated Chamber and Piston Based Method)

Importancia y uso:

5.1 The tendency of a fuel to vaporize in automotive engine fuel systems is indicated by the vapor-liquid ratio of the fuel.

5.2 Automotive fuel specifications generally include
T_{(V/L = 20)} limits to ensure products of suitable volatility performance. For high ambient temperatures, a fuel with a high value of T_{(V/L = 20)}, indicating a fuel with a low tendency to vaporize, is generally specified; conversely for low ambient temperatures, a fuel with a low value of T_{(V/L = 20)} is specified.
