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. Characterization of the fuel spray from a low-pressure gasoline port fuel injector is quite important, however, these spray characterization tests are not addressed in this document, but are covered in a companion publication: SAE J2715.
