Professional HEUI Injector Test Bench and Calibration Stand for Caterpillar Engines
The HEUI Test Bench is a high-performance diagnostic system specifically engineered for Hydraulic Electronic Unit Injectors (HEUI). It provides a comprehensive solution for testing and calibrating injectors used in Caterpillar C7, C9, C-9, 3126, and Ford Powerstroke engines. This bench features a dual-circuit system that accurately simulates both high-pressure actuation oil and fuel delivery under real-world engine conditions. Equipped with a professional control system and high-precision flow sensors, it allows for the precise measurement of injection volume, return flow, and solenoid response time. Whether you are performing routine maintenance or deep-level reconditioning, this HEUI stand ensures your injectors meet stringent emission and power standards.











Full HEUI Range Support: Perfectly compatible with Caterpillar C7, C9, C-9, 3126, 3126B, and various HEUI fuel systems.
Dual-System Simulation: Simultaneously controls actuation oil pressure and fuel pressure to replicate authentic engine operation.
High-Precision Metering: Utilizes industrial-grade flow sensors to provide stable and repeatable data for injection and return volumes.
Professional Adapter Kit: Comes with a complete set of specialized fixtures and high-pressure oil/fuel lines for quick and secure mounting.
Advanced Solenoid Analysis: Measures the Begin of Injection Period (BIP) and electrical response time to ensure balanced engine performance.
Intelligent Control Software: Features a built-in database with standard test plans, supporting automatic testing and report generation.
Robust Safety Features: Includes over-pressure protection and emergency stop functionality to protect both the operator and the injectors.
