ABSTRACT:
A rate tube measurement system for measuring injected fuel and a method thereof are disclosed. In one embodiment, the system includes a fixture assembly, a rate tube fluidically connected to the fixture assembly to receive fuel injected by the fuel injector during, a pressure sensor positioned upstream of the rate tube that is adapted to measure pressure changes in the injected fuel and provide a pressure output, a flow meter that measures flow of injected fuel and provides a flow output indicative of the measured fuel flow, and a computing device that processes the duration of actuation, the pressure output and the flow output to determine injection information such as fuel injection quantity, variation, and rate shape.
