J2713_201808 Direct Injection Gasoline Fuel Injector Characterization

The use of uniform and standardized testing and evaluation procedures for fuel injectors is important to the worldwide automotive community. Standardized test procedures provide both injector manufacturers and end-users with one accepted test for each of the key injector performance parameters, instead of a specialized test protocol for each of many customers and applications. The use of these procedures for test configurations, testing methods, data reduction and reporting that are contained in this document will significantly enhance the ability of one test laboratory to accurately repeat and verify the results of another.

Gasoline direct injection (GDI) differs substantially from port fuel injection (PFI), hence the existing PFI recommended practice document (SAE J1832) cannot be employed. The application of GDI has rapidly expanded worldwide. Prior to this document, a recommended practice for GDI injectors was not available. This recommended practice will permit the automotive industry to evaluate, characterize and compare GDI hardware.
