System for calibrating an integrated injection nozzle and injection pump

摘要

A fuel injection system ( 18 ) is calibrated as an assembled system. The fuel injection system ( 18 ) includes a unit pump ( 10 ) a cam follower ( 24 ), a joined fuel injection line ( 14 ) and injection nozzle ( 16 ). The fuel injection system ( 18 ) is mounted to a test stand an is subsequently calibrated to a specified fuel delivery and timing. The relative positions of the unit pump ( 10 ) and fuel injection nozzle ( 16 ) are fixed during calibration. The assembled fuel injection system is packaged and delivered so that the calibrated system can be installed in the relative positions fixed during calibration.
