This part of ISO 13555 specifies a test rig and reference method for the validation of timing measurement devices which, by application of the pressure-sensing principle on the high-pressure fuel injection pipe, are used for checking the dynamic setting of fuel injection equipment fitted to diesel engines. (In order to produce a realistic measurement situation, the test rig allows the addition of vibrational excitation of the high-pressure fuel injection pipe —deemed a primary source of signal corruption when used on running diesel engines.) The validation procedure can be used either in the initial approval of a timing measurement device or the verification of its proper functioning when already in use. The aim is to ensure that the devices supplied by different manufacturers provide comparable measurement results.
