This is a hybrid diesel fuel system service platform dual-purpose for mechanical pumps and electronic injectors. It takes advantage of the stable power and hydraulic foundation of the Bosch EPS 619, integrated with the Hartridge HK1400 EUI/EUP (Electronic Unit Injector / Electronic Unit Pump) testing module. It realizes dual functions in one unit, covering full-range maintenance from traditional mechanical pumps to electronically controlled injectors.
Business Coverage: Dual-Purpose Design & Full Compatibility
As the core value of this integrated upgrade, it achieves the performance of two professional devices in one:
Fully retained OEM mechanical pump functions
The original structure of the EPS 619 remains intact. All original functions are fully available, including calibration of in-line pumps and VE distributor pumps, governor testing, and fuel delivery uniformity inspection, with no impact on mechanical pump servicing.
Added high-end electronic injector maintenance capability
After integration, it supports EUI/EUP testing for mainstream models such as Cummins HPI, Caterpillar, Scania and Volvo. It covers high-value repair orders for commercial vehicles and construction machinery, solving the industry pain point that conventional test benches cannot handle high-end electronic fuel injection systems.
Performance & Precision: Complementary Advantages with High Stability
Superior basic platform & power system
Relying on the original spindle power, hydraulic fuel supply system and precise speed control of the Bosch EPS 619, it delivers steady torque and minor speed fluctuation. It provides a reliable power source for the Hartridge module and avoids test errors caused by insufficient power and unstable speed on ordinary domestic test benches.
High-precision upgrade by Hartridge module
Equipped with patented adjustable cam drive, it accurately simulates engine injection timing, lift and injection rate to restore real working conditions of injectors. Its testing precision is fully comparable to imported professional benches.Supported by dedicated high-precision flow sensors and original database software, it compares measured data with OEM standard values to accurately detect leakage volume, fuel delivery and solenoid valve performance, meeting the strict accuracy requirements for remanufacturing and high-standard repair.
