This SAE Recommended Practice promotes uniformity in the evaluation and qualification tests conducted on GDI fuel injectors used in gasoline engine applications, where fuel pressures are typically well above 1 MPa. The document scope is limited to electrically-actuated fuel injection devices used in automotive GDI systems and is primarily restricted to bench tests.

The scope of this Recommended Practice is limited to gasoline fuel pumps used in automotive direct fuel injection systems. It is primarily restricted to bench tests. This SAE Recommended Practice also defines the minimum design verification testing that is recommended to verify the suitability of Gasoline Direct Injection (GDI) High Pressure fuel pumps used for pumping gasoline or gasoline blend fuels. Additional tests not specified in SAE J2714 will be required for non-automotive pump applications or pumps, such as those intended for use on aircraft, motorcycles, or marine equipment. Except where stated, test results are recorded for individual parts under recommended test conditions. Where population characteristics are reported, the sample size, selection method, and statistical analysis technique must be explicitly stated.

This SAE Recommended Practice Document promotes uniformity in the evaluation tests and performance measurements that are conducted on fuel injectors that are used in low-pressure gasoline engine applications. The scope of this document is limited to electronically-actuated fuel injection devices that are utilized in automotive gasoline port fuel injection systems where the fuel supply pressure is usually below 1000 kPa (low-pressure). Detailed test procedures are provided for determining numerous PFI injector parameters, including, but not limited to, flow curves, leakage, electromechanical performance, fluid compatibility and corrosion susceptibility, durability, the effects of vibration and torsional deflection, thermal cycling effects and noise. The standardized measurement procedures in this document are all bench tests.
