Diesel Fuel Injection Pump - Validation of Calibrating Nozzle Holder Assemblies
2021-03-17
CURRENT
J1549_202103
The fuel injection pump is intended to validate the accuracy of calibrating nozzle and holder assemblies for applications using 0.4 - 0.8 mm diameter orifice plates and to assist in identifying problems in fuel injection pump test stands. This SAE Recommended Practice is divided into two parts: Part I—Design, Description and Specifications of the Fuel Injection Pump; and Part II—Test Procedures for Using the Fuel Injection Pump.

Diesel Engines - Fuel Injection Pump Testing
2021-03-17
CURRENT
J1668_202103
The correct setting and adjustment of fuel injection pumps requires standardized testing conditions. This SAE Standard summarizes the design and operating parameters for test benches so that, using certain information supplied by the pump manufacturer, the pump test schedule, and certain information supplied by the test bench manufacturer, it can be determined whether a particular test bench is suitable for driving a particular injection pump. This document is in most cases a summary of the ISO Standard 4008, Parts 1, 2, and 3 and is intended to provide its critical aspects. Standard ISO 4008 should be referred to for more details.

Diesel Injection Pump Testing—Part 2: Orifice Plate Flow Measurement
2021-03-17
CURRENT
J968/2_202103
This part of SAE J968 specifies the flow measuring system, including the fixture, to be used for flow testing the single hole orifice plates used in an orifice plate type nozzle and holder assembly (described in SAE J968/1) which is intended for testing and setting diesel fuel injection pumps on test benches. The flow measuring system and fixture ensure accurate flow testing of the entire range of orifices from 0.4 to 0.8 mm diameter as specified in SAE J968/1. It is intended primarily for use by the manufacturers of single hole orifice plates.
