The CR304 Common Rail Injector Test Bench is a high-productivity diagnostic station designed for professional diesel workshops that require volume processing. Unlike standard testers that handle one injector at a time, the CR304 is engineered to test 4 injectors simultaneously, significantly reducing turnaround time.
Key Features:
Simultaneous Testing: Standard configuration supports testing 4 injectors at once. Ideally suited for servicing 4-cylinder engines in a single run.
Powerful Performance: Equipped with a 7.5KW 380V 3-phase motor, providing ample torque and stable rail pressure to support the flow demand of multiple injectors opening simultaneously.
Broad Compatibility: Fully supports both electromagnetic (Solenoid) and Piezoelectric injectors (Bosch, Denso, Delphi, Siemens, CAT, etc.).
Premium Hardware: Features a High-Quality Injector Mounting Bracket/Fixture. This upgraded clamping system ensures quick installation, secure locking, and prevents leakage during high-pressure testing.
Expandability: The system is flexible and can be customized to test 6 injectors (optional) upon request, catering to 6-cylinder engine maintenance needs.


Maximum Efficiency: Increases workshop throughput by 400% compared to single-station testers. You can finish a full set of vehicle injectors in the time it takes to test just one.
Heavy-Duty Fixtures: The High-Quality Injector Bracket is a standout feature. It is robust, easy to adjust, and durable, solving the common pain point of cheap fixtures that wobble or leak.
Stable Pressure: The 7.5KW industrial motor ensures that the rail pressure remains stable even when 4 injectors are injecting fuel simultaneously, guaranteeing accurate test results.
Versatile Upgrade: Offers the flexibility to upgrade to a 6-injector testing capacity, making it a future-proof investment for servicing larger trucks and machinery.
Comprehensive Testing: Capable of performing leak tests, full-load, idle, and pre-injection tests for all connected injectors in one automated sequence.
