Direct Injection Gasoline Fuel Injector Characterization

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J2713_201808
  • Current
Published 2018-08-28 by SAE International in United States
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.

Low Pressure Gasoline Fuel Injector

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J1832_201610
  • Current
Published 2016-10-04 by SAE International in United States
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. Tests and references to low-pressure gasoline injectors that are no longer commonly used in modern production are not included in the main body of this document. Superseded systems such…

Gasoline Direct Injection Pump

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J2714_201502
  • Current
Published 2015-02-20 by SAE International in United States
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.

Validation Testing of Electric Fuel Pumps for Gasoline Fuel Injection Systems

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J1537_201304
  • Current
Published 2013-04-29 by SAE International in United States
This SAE Recommended Practice defines the minimum design verification testing required to verify the suitability of in-tank mounted electric motor driven fuel pumps used for pumping gasoline or gasoline blend fuels. Additional tests not specified in SAE J1537 will be required for frame mounted pump applications or pumps intended for use on aircraft, motorcycles, or marine equipment.

Fuel Injection System Fuel Pressure Regulator and Pressure Damper

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J1862_201210
  • Current
Published 2012-10-15 by SAE International in United States
This SAE Recommended Practice promotes uniformity in the evaluation and qualification tests conducted on fuel pressure regulators and pressure dampers used in gasoline engine applications. Its scope is limited to fuel pressure regulators and dampers used in automotive port and throttle body fuel injection systems where fuel supply pressure is below 1000 kPa. It is further restricted to bench type tests. More specifically, this document is intended for use as a guide to the following: a Identify and define those parameters that are used to measure fuel pressure regulator and pressure damper characteristics of performance. The parameters included in this document are: 1 Slope 2 Operating Flow Range 3 Repeatability 4 Hysteresis 5 Dynamic Response b Establish test procedures and recommend test equipment and methods to measure and quantify these parameters. c Establish test procedures and recommend test equipment and methods to quantify simulated field reliability over the life of the component. d Standardize the nomenclature as related to fuel pressure regulation and pressure damping for fuel injection systems. e Except where stated, test results…

Gasoline Fuel Injector Spray Measurement and Characterization

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J2715_200703
  • Current
Published 2007-03-14 by SAE International in United States
This SAE Recommended Practice promotes uniformity in the characterization tests conducted on sprays generated by automotive fuel injectors used in both port fuel injection and gasoline-direct injection engine applications. SAE J2715 contains the detailed background, procedures and data reduction protocols for nearly all fuel spray characterization metrics that are applicable to automotive applications. It is intended to be utilized in conjunction with other SAE J documents that address injector performance metrics. These are SAE J1832 for Port Fuel Injection and the forthcoming SAE J2713 for Gasoline Direct Injectors.
