CRC (Coordinating Research Council) Hot-Start and Driveaway Driveability Program at High and Intermediate Temperatures Using Gasoline-Alcohol Blends

Abstract

A cooperative CRC test program was conducted at Failure Analysis Associates Test Track in Phoenix, Arizona, from September 4 through October 4, 1985. The program investigated the hot-start driveability of thirteen 1985 model vehicles with eight hydrocarbon-alcohol blends and two hydrocarbon-only gasolines at nominal ambient temperatures of 90 F and 70 F. The driveability procedure was modified to emphasize conditions which may cause fuel foaming. Carburetted, throttle-body-injected (TBI), port-fuel-injected (PFI), and port- fuel-injected turbocharged fuel systems were represented in the vehicle fleet. Ambient temperature effects were highly significant for carburetted and throttle-body-injected vehicle fuel-metering systems and for the total fleet. Carburetted vehicles were more sensitive to fuel properties and ambient conditions than fuel-injected vehicles.
