Reman Process
Micro-Precision Remanufacturing
The geometry of the nozzle needle and its process-reliable remanufacturing are especially important for the required fine fuel nebulisation. Therefore AYB ENDUSTRI has started Microskopic Grinding re-manufacturing processes at a dedicated micro precision manufacturing site.
Assembly in a Clean Room
Extreme care is necessary during assembly to ensure the functional capability of the high-precision parts in the Com-mon Rail system. The parts must be absolutely dust and oil-free, therefore they are cleaned in four separate washing cycles. High pressure pump, high pressure connector and injector components are assembled in a clean room after acclimatisation to ensure absolute precision during assembly.
Assembly Monitoring
On the assembly line, which is configured for series production and largely automated, all manual process steps are monitored by the system technology. Operating errors are practically eliminated by the quality management system.
| Spray pattern test bench:With the aid of a camera, the test bench measures the geometry of the spray pattern of the injector Injector Leak Test: With the aid of a camera system, the leak tightness of the nozzle and nozzle needle is checked. In the process, the camera records any drop formation on the nozzle which is subjected to high pressure. Geometry Measurements: Modern measurement instruments are used to measure the geometry of the Common Rail system parts. The photo shows the evaluation of the round surface of the control valve. |
