HEUI-FS CAT C7 C9 HEUI Injector Test Bench

The HEUI-FS HEUI Injector Test Bench is a compact professional testing system designed for testing CAT C7, C9 and 3126B HEUI injectors.

The standard configuration includes dedicated adapters for C7, C9 and 3126B injectors, allowing technicians to perform comprehensive injector performance testing. The system uses separate engine oil and diesel fuel circuits, with independent oil and diesel tanks and dedicated flow sensors for accurate measurement.

The test bench supports measuring-cylinder testing and computer-based display of test results. Test data can be monitored through the computer system, helping technicians evaluate injector performance under different operating conditions.

With a 2.2KW motor, compact dimensions of approximately 100 × 85 × 100 cm and a net weight of about 220 kg, HEUI-FS is suitable for professional diesel injector repair shops that need dedicated HEUI testing capability without a large industrial test bench.

Standard Test Models

The standard configuration supports:

• CAT C7 HEUI injectors

• CAT C9 HEUI injectors

• CAT 3126B HEUI injectors

Optional Test Systems

Optional adapters and test systems are available for:

• CAT 3126A

• CAT 3126B

• CAT 3412E

• Isuzu HEUI

• Ford G2.8

• VE – Fuel delivery/performance test

• START – Starting condition test
  

Product Advantages

Dedicated HEUI Testing System
Designed specifically for HEUI injectors, providing a focused solution for CAT and other HEUI injector repair applications.

Dual Fluid Circuits
The machine uses separate engine oil and diesel fuel circuits to simulate the two-fluid operating principle of HEUI injectors.

Independent Oil and Diesel Tanks
Dedicated tanks help separate the engine-oil and diesel-fuel testing circuits and simplify workshop operation.

Oil and Diesel Flow Sensors
Flow sensors measure the relevant fluid flow during testing and provide digital test results.

Standard C7/C9/3126B Adapters
The standard configuration includes adapters for CAT C7, C9 and 3126B injectors, allowing immediate testing of these common HEUI applications.

Computerized Test Results
Testing results are displayed through the computer system, making it easier to record and compare injector performance.

Compact Workshop Design
With a size of approximately 100 × 85 × 100 cm and a weight of around 220 kg, the HEUI-FS requires less workshop space than large multi-function test benches.

Expandable Configuration
Optional test systems allow the same platform to be expanded for CAT, Ford, Navistar and Isuzu HEUI injector applications.
