Abstract : In previous CRC studies, equations were developed to predict vehicle driveability at intermediate ambient temperatures (nominally 40-70 F) as a function of gasoline distillation properties. Such equations are useful for predicting the driveability performance of commercial gasolines. The purposes of the present study were: (1) to supplement those previous studies at intermediate temperatures with data for 1980 model year vehicles with and without closed-loop fuel control systems; and (2) to determine the relationship between fuel volatility and vehicle driveability at low ambient temperatures (20 F), thus expanding the applicability of equations for predicting driveability performance.
