Original Abstract Submitted
A method for testing a fuel injector for an internal combustion engine, the method comprising: providing a fuel injector having a nozzle outlet; determining a control pulse duration range corresponding to a range of a quantity of injected fuel; determining a number of fixed durations of the control pulse within the duration range; selecting a plurality of operating points of the internal combustion engine, the plurality of operating points being defined by the number of fixed durations of the control pulse and the selected set of operating conditions; based on the determined control pulse duration range, the injected fuel quantities, and the selected operating conditions, controlling a backpressure level at the nozzle outlet of the fuel injector so as to set backpressure levels expected to occur in the internal combustion engine during its operation in use within the determined control pulse duration range.
