CR309 Professional Common Rail Injector Test Bench with Automatic Measurement
The CR309 Common Rail Injector Test Bench is a high-precision diagnostic device engineered to simulate the working conditions of a diesel engine ECU. It provides high-pressure common rail system control signals for Bosch, Denso, Delphi, and Piezoelectric injectors. Equipped with an industrial PC and a Windows-based operating system, the CR309 offers fully automatic testing of injection flow and return oil. Its compact design and high-pressure stability (up to 2000 bar) make it an essential tool for professional diesel workshops specializing in injector maintenance and repair.












Fully Automated Operation: Automatically adjusts rail pressure and motor speed, measures fuel flow via high-precision electronic sensors, and generates detailed test reports without manual intervention.
Comprehensive Brand Support: Integrated database covers thousands of test plans for Bosch, Denso, Delphi, Siemens, and third-generation Piezoelectric injectors.
Industrial-Grade Control: Powered by a stable industrial PC with a user-friendly interface, supporting multi-language operations and remote system updates.
Dual Testing Modes: Features "Normal Test" for comprehensive analysis and "Quick Test" (20 seconds per condition) for high-efficiency workshop throughput.
Precise Pressure Management: Utilizes an original common rail pump and intelligent PID algorithms to maintain stable rail pressure up to 2000 Bar.
Safety & Reliability: Includes built-in short-circuit protection and pressure overload safety protocols to ensure the longevity of both the machine and the injectors being tested.
Data Management: Allows users to add, edit, and save custom injector part numbers and parameters in the searchable database.
