HEUI-FS HEUI Injector Test Bench for CAT C7, C9 and 3126B

Product Introduction

The HEUI-FS HEUI Injector Test Bench is a professional testing solution designed for the inspection and performance testing of HEUI injectors. The standard configuration is equipped with adapters for CAT C7, C9 and 3126B HEUI injectors.

Unlike conventional common rail injector test benches, the HEUI-FS uses a dual-fluid circuit with separate engine oil and diesel fuel systems to reproduce the working conditions required for HEUI injector testing.

The machine is equipped with dedicated oil and diesel flow sensors, allowing technicians to monitor fluid flow during the test. Test results are displayed on a computer for convenient analysis and comparison.

The HEUI-FS supports the main testing points of LEAK, VL, LL, VE and START, providing a practical testing platform for professional HEUI injector repair and service.

With a 2.2KW motor, compact dimensions of approximately 100 × 85 × 100 cm, and a weight of about 220 kg, the machine is suitable for professional diesel workshops where dedicated HEUI testing capability is required.

Standard Configuration

The standard HEUI-FS configuration includes:

• C7 HEUI injector adapter

• C9 HEUI injector adapter

• 3126B HEUI injector adapter

• Engine oil tank

• Diesel fuel tank

• Oil flow sensor

Main Test Points

LEAK

Checks injector leakage performance and helps identify abnormal internal leakage.

VL

Tests injector performance under the specified VL operating condition.

LL

Evaluates injector performance under the LL test condition.

VE

Tests fuel delivery performance and evaluates injector fuel output.

START

Tests injector performance under starting conditions.

Optional Applications

With optional adapters and configurations, the HEUI-FS can be expanded to test additional HEUI injector applications, including:

• CAT 3126A

• CAT 3126B

• CAT 3412E

• Isuzu HEUI

• Ford G2.8

• Ford G2.9

• Navistar HEUI

This expandable design allows workshops to configure the machine according to the injector models they service.

Product Advantages

Dedicated HEUI Testing Platform

The HEUI-FS is designed specifically for HEUI injector testing, making it a focused solution for workshops specializing in Caterpillar and other HEUI systems.

Dual Oil and Diesel Circuits

HEUI injectors use engine oil as the hydraulic driving medium and diesel fuel for injection. The HEUI-FS provides separate oil and diesel circuits to support this testing principle.

Independent Fluid Tanks

Separate engine oil and diesel fuel tanks simplify fluid management and help maintain independent testing circuits.

Oil and Diesel Flow Measurement

Dedicated flow sensors monitor the oil and diesel circuits during testing, providing useful measurement data for injector diagnosis.

Computerized Test Results

Testing results are displayed on the computer, allowing technicians to conveniently monitor and compare injector performance.

Standard C7, C9 and 3126B Adapters

The standard configuration is ready for three important HEUI applications: CAT C7, CAT C9 and CAT 3126B.

Compact Design

The approximately 100 × 85 × 100 cm footprint makes the HEUI-FS suitable for workshops that require specialized HEUI testing without occupying excessive floor space.

Expandable Testing Capability

Optional adapters allow the machine to cover additional CAT, Isuzu, Ford and Navistar HEUI injector applications.

Applications

The HEUI-FS is suitable for:

• HEUI injector repair workshops

• Caterpillar injector service centers

• Diesel fuel injection repair shops

• Heavy-duty diesel engine workshops

• Construction machinery maintenance

• Mining equipment service

• Truck and commercial vehicle repair

• Agricultural machinery repair

• Diesel injector remanufacturing

• HEUI injector testing and calibration

• Diesel fuel system laboratories
