The CR304S Common Rail Diesel Injector Test Bench is a high-efficiency diagnostic machine designed for busy diesel repair workshops. Its most distinguishing feature is the capability to test four injectors simultaneously, significantly reducing turnaround time compared to single-station benches. Powered by a robust 5.5KW motor, it ensures stable pressure generation for accurate testing results.
Unlike traditional test benches that require screwing on high-pressure oil pipes for every test, the CR304S utilizes an innovative hinged guide rail design (Quick Clamping System). This allows technicians to mount injectors directly without external high-pressure pipes, making setup incredibly fast and preventing oil leakage. The system supports full diagnostics for both Solenoid and Piezo injectors and generates coding (IMA/ISA/QR/IIC) for major brands like Bosch, Denso, Siemens, and Delphi. This machine is the ultimate tool for maximizing daily output and service capability.


Quad-Station Testing: capable of testing 4 injectors at the same time, increasing work efficiency by 400%.
Quick Clamping Design: Features a hinged guide rail structure that eliminates the need for connecting high-pressure oil pipes, saving vast amounts of mounting time.
Comprehensive Coding: Generates coding for Bosch, Denso, Delphi, and Siemens injectors to ensure perfect ECU matching.
Versatile Compatibility: Fully supports both traditional Solenoid injectors and modern Piezo injectors.
Powerful Performance: Equipped with a 5.5KW motor to provide stable rail pressure and flow for heavy-duty testing.
