Professional HEUI-B Injector Test Bench and Calibration Stand for Caterpillar Engines

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.

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.
