EFFECTS OF FUEL VOLATILITY ON DRIVEABILITY OF 1980 MODEL CARS AT LOW AND INTERMEDIATE AMBIENT TEMPERATURE

In previous CRC studies, equations were developed to predict vehicle driveability at intermediate ambient temperatures (nominally 40-70 deg 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 (less than 20 deg F), thus expanding the applicability of equations for predicting driveability performance.
