EUI EUP-A Electronic Unit Injector and Unit Pump Repair Test Bench
The EUI EUP-A Test Bench is a specialized diagnostic solution designed to simulate the Engine Control Unit (ECU) conditions for Electronic Unit Injectors (EUI) and Electronic Unit Pumps (EUP). It provides professional drive signals to accurately test components from leading manufacturers such as Bosch, Delphi, Cummins, Caterpillar, and Volvo. This bench is essential for identifying performance issues in heavy-duty diesel engines, allowing for precise adjustment of injection timing and fuel delivery volume under various simulated load conditions.









Professional ECU Simulation: Advanced electronic control system that perfectly mimics the driving signals of modern diesel engine ECUs for precise EUI/EUP diagnostics.
Wide Application Range: Compatible with a vast range of EUI/EUP systems including Bosch, Cummins, Delphi, CAT, Volvo, Scania, and more.
High Precision Measurement: Equipped with industrial-grade sensors to provide accurate data on fuel injection quantity and response time.
Stable Performance: Features a robust mechanical design and high-quality electronic components to ensure reliable operation in demanding workshop environments.
User-Friendly Interface: Intelligent software with a clear LCD display allows operators to easily monitor parameters and manage test results.
Comprehensive Protection: Built-in safety protocols for high-voltage components and pressure overload to protect both the operator and the equipment.
Easy Maintenance: Designed for long-term durability with accessible components for regular calibration and cleaning.
