| индекс фракционного состава | Drivability Index (Driveability Index (DI) = 1.5 T10 + 3.0 T50 + 1.0 T90 + 1.33 °C (2.4 °F) × Ethanol Volume %, where T10 = distillation temperature, °C (°F), at 10 % evaporated, T50 = distillation temperature, °C (°F), at 50 % evaporated, T90 = distillation temperature, °C (°F), at 90 % evaporated, and 1.33 is the coefficient for the volume % ethanol present when the distillation results are determined in degrees Celsius and 2.4 is the coefficient when distillation results are determined in degrees Fahrenheit. wchupin) |
