Product Code:SAE J968/1
Title:Diesel Injection Pump Testing-Part 1: Calibrating Nozzle and Holder Assemblies
Issuing Committee:Diesel Fuel Injection Equipment Standards Committee
Scope:This part of SAE J968 specifies two types of calibrating nozzle and holder assemblies intended for the testing and setting of diesel injection pumps on test benches. It applies to: a. A calibrating nozzle and holder assembly with a single hole orifice plate; b. A calibrating nozzle and holder assembly with a delay pintle type nozzle.The approximate range of the calibrating nozzle and holder assembly is up to: a. 300 mm{sup}3/stroke with the single hole orifice plate; b. 150 mm{sup}3/stroke with the delay pintle type nozzle. Setting and maintenance requirements are specified in ISO 4008/3.
