适用范围

This part of ISO 8984 specifies minimum requirements for hand-lever-operated testing and setting apparatus to perform certain tests on fuel injectors for compression-ignition engines for road vehicles. These tests are detailed in ISO 8984-2 and are — nozzle opening pressure; — chatter (atomization); — spray pattern; — seat leakage; — back-leakage. This International Standard concerns fuel injectors having a spring-loaded nozzle valve actuated by fuel pressure. It is in-tended that the specifications form a standard basis. The injec-tor is connected to the apparatus by an adaptor specified by the injector manufacturer.
