Abstract
An apparatus and a method for testing a fuel injector nozzle with a tip having at least one fuel outlet are provided. The apparatus comprises a test chamber, a holder for holding the fuel injector nozzle such that the outlet is within the test chamber, a fuel supply arrangement for supplying fuel to the fuel injector nozzle, a sensor having a sensor surface for sensing an atomized fuel spray supplied by the fuel injector nozzle through the fuel outlet and movement module for moving the sensor. The movement module is configured to position the sensor surface of the sensor at a plurality of positions corresponding to a surface of a sphere having a radius R and a center point C adjustable to match a center point ct of the tip of the fuel injector nozzle or a center point cf of an orifice of the fuel outlet.
