HEUI-F HEUI Common Rail Injector Test Bench for Caterpillar C7 C9 3126B

HEUI-F HEUI Common Rail Injector Test Bench for Caterpillar C7 C9 3126B

The HEUI-F HEUI Common Rail Injector Test Bench is a specialized diagnostic platform designed to simulate the Engine Control Unit (ECU) working conditions of diesel engines. It provides high-precision control signals for HEUI injectors such as Caterpillar C7, C9, and 3126B. The machine allows maintenance personnel to set and save drive signal parameters according to actual conditions, facilitating accurate judgment and repair of the high-pressure common rail system's working status.

HEUI Hydraulic Electronic Unit Injector Platform

The platform is purpose-built for Caterpillar HEUI (Hydraulic Electronic Unit Injector) families used in commercial and off-road diesel engines. High-pressure oil rail simulation and electronic control signal generation provide full diagnostic coverage for Caterpillar C7 / C9 / C12 / C15 3406E / 3126B, Navistar DT466 / DT530 / DT570, and International HEUI applications.

Caterpillar Engine Coverage and Diagnostic Functions

The HEUI test bench supports the full Caterpillar HEUI engine family across on-highway trucks, construction machinery and marine applications. Calibration profiles include idle speed, partial load, full load and overspeed protection. Integrated high-precision flow meters deliver ±0.5% measurement accuracy for injector return-flow analysis.

FAQ — Frequently Asked Questions

Q1. What HEUI injectors are supported?
A: Caterpillar C7 / C9 / C12 / C15 3406E / 3126B HEUI injectors and Navistar DT466 / DT530 / DT570 HEUI injectors.

Q2. Does the platform simulate high-pressure oil rail?
A: Yes. Integrated high-pressure oil pump provides variable oil pressure from 0 to 30 MPa to simulate engine working conditions.

Q3. Is flow measurement accurate?
A: The high-precision flow meter delivers ±0.5% accuracy for return-flow and injection quantity analysis.

Q4. What languages does the software support?
A: English, Spanish, Russian, French, Arabic and more than 15 languages are available.

Q5. Is the platform suitable for commercial diesel service centers?
A: Yes. The industrial-grade design supports continuous commercial operation in professional Caterpillar service workshops.

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.
