ABSTRACT:
Disclosed is both an apparatus and method for quantifying an injection event of a fuel injector, including both multiple pulse and single pulse injection events. Typically, the fuel injector is a common rail injector. The apparatus includes a pressure chamber for isolating a portion of the injection pressure for reducing pressure waves and reflections which can create “noise” in the detection of an injection pressure. The invention further includes determining the precise start and end times of injection using cavitation created by the injection event by determining the intensity of light within a spray chamber.
