ABSTRACT:
A method of testing a fuel system of an internal combustion engine comprises measuring the instantaneous speed of a component of a pumping apparatus of the system this speed decreasing as fuel is pressurised to achieve fuel delivery to the engine as compared with the nominal engine speed due to "wind up" in the drive to the engine. The speed profiles obtained as fuel is supplied to each injection nozzle and compared to determine if the injection nozzles are working correctly.
