In a common-rail fuel injection system, measurement data on a pressure feed rate characteristic, reflecting diverse individual differences among supply pumps (6), is divided into N portions which in turn are ranked and encoded to produce ranked pressure feed rate characteristic codes (21), and one of the ranked codes (21) is distinguishably put or printed on a portion of the pump (6) confirmable or visible from the external. Moreover, measurement data on a leak rate characteristic, reflecting diverse individual differences of injectors (4), is divided into M portions which in turn are ranked and encoded, and one of the resultant ranked leak rate characteristic codes (22) is distinguishably put or printed on a portion of the injector (4) confirmable from the external. This enables the pressurization performance of the system to be enhanced without requiring a considerable structure alteration of the pump (6). |
