Abstract: A method of testing a fuel injection system or components thereof includes running a high pressure fuel pump to provide fluid under pressure to the fuel injection system or components. The pump flow is controlled via an inlet metering valve by controlling current or voltage supplied to the inlet metering valve dependent on the power to the fuel pump.

Abstract: A driveshaft assembly, for example in an Electronic Unit Injector, Unit Injector or Electronic Unit Pump testing machine, wherein an indexing arrangement, such as complementary external and internal splines, enables a cam to be mounted on a shaft at a number of discreet positions, each providing a different offset of a central axis of the base cylinder section from a central axis of the shaft, each position providing a different maximum lift value of a plunger in contact with the cam, directly or via a rocker arm.
