CR311 High Pressure Common Rail Injector Test Bench with Coding Function
The CR311 (CRS311) Common Rail Injector Test Bench is a state-of-the-art diagnostic device designed to test and calibrate high-pressure common rail injectors. Controlled by a high-performance industrial computer running a Windows operating system, it utilizes an original Bosch/Denso common rail pump to provide a stable rail pressure of up to 2000 bar. The system measures oil quantity via advanced electronic sensors and displays real-time data on the screen. It is specifically engineered to handle injectors from Bosch, Siemens, Delphi, and Denso, offering a complete solution for modern diesel fuel system maintenance, including the generation of essential injector compensation codes.











High-Pressure Performance: Capable of generating up to 2000 bar pressure, ensuring compatibility with the latest generation of high-pressure injectors.
Automatic Coding Function: Supports the generation of various injector compensation codes (QR codes) to ensure precise engine fuel mapping.
Precision Electronic Measurement: Features a high-accuracy flow sensor for automatic measurement of injection and backflow volumes with digital display.
Comprehensive Brand Support: Fully compatible with mainstream common rail injectors, including Bosch, Denso, Delphi, and Siemens.
Intelligent Software System: Built on a Windows OS with a searchable database of thousands of test plans, allowing users to save, edit, and add new data.
Reliable Safety Protection: Integrated with automatic pressure adjustment and pressure overload protection to ensure safe operation under high-load conditions.
Industrial Grade Design: Features high-quality internal components and a stable drive system for low-noise, high-reliability daily workshop use.
