Methodology for Evaluating Fuel Dispenser Nozzle Characteristics

This paper proposes methods for measuring dispenser nozzle characteristics considered to be potential inputs to the On-Board Refueling Vapor Recovery (ORVR) design process. In fact, these characteristics are potential design inputs to all refueling design processes. Experiments were conducted to develop test procedures and equipment that provide consistent measurements for the broadest possible range of dispenser nozzles. The feasibility of the proposed methods is demonstrated with some simple measurements conducted on common nozzles.
