Abstract
A test station for fuel injection pump includes a test container enclosing an air space into which a fuel injection nozzle under test opens. A microphone communicates with the air space to convert air pressure pulses resulting during each injection into a corresponding electrical signal. The integral of the output signals from the microphone is a measure for the quantity of the injection fuel. The total quantity of injected fuel can be determined by a calibration system.
