HEUI-FS HEUI Common Rail Injector Test Bench

HEUI-FS HEUI common rail injector Test Bench

The HEUI-FS HEUI Common Rail Injector Test Bench is a professional test bench specially designed for HEUI (Hydraulically actuated Electronically controlled Unit Injector) injector testing. It imitates the working conditions of the diesel engine ECU and provides control signals for CAT C7, C9, 3126B and similar HEUI injectors, allowing maintenance personnel to judge and maintain the working status of the high-pressure common rail system.

Equipped with a dual oil system (HEUI 74 data), the bench tests HEUI injectors with two fixtures for CAT C7/C9 and 3126B as standard. Optional functions extend testing to CAT 3126A, 3412E, NAVISTAR, ISUZU, Ford G2.8 and G2.9 HEUI injectors. The control system software supports 15 languages, can be updated automatically and remotely, and can print test reports with your own logo.

Supported HEUI Injector and Pump Applications

The HEUI test platform covers Caterpillar C7 / C9 / C12 3126B, Navistar DT466 / DT570 / DT530, Ford Power Stroke 7.3L / 6.0L, Perkins 1300 series and International HEUI applications. Representative OEM references include Caterpillar 10R-7675 / 10R-7676 / 10R-7677, Navistar / International 1807329C92 / 1845428C92 / 1882080C92, and Ford F81Z-9E527-AA / F6TZ-9E527-AA.

Hydraulic Electronic Unit Injector Calibration Workflow

The hydraulic actuation is generated by the high-pressure oil pump driven by the test bench. The platform performs injector response time measurement, injection quantity calibration and full-load sealing tests across 6 / 8 cylinder configurations without engine removal.

FAQ — Frequently Asked Questions

Q1. Which diesel engines are covered by this HEUI platform?
A: Caterpillar C7 / C9 / C12 3126B, Navistar DT466 / DT570, Ford Power Stroke and similar HEUI applications.

Q2. Is hydraulic actuation integrated?
A: Yes. The integrated high-pressure oil pump drives HEUI actuation without engine dismount.

Q3. Can this test bench test both HEUI injectors and HEUI pumps?
A: Yes. Both HEUI injectors and HEUI pumps are supported with dedicated adapter kits.
