In the fuel injection system of a car, the Common Rail (CR) fuel injection system is a high-efficiency technology that uses a combined high-pressure fuel pump and injector to inject high-pressure fuel into the cylinders of the engine. The CR fuel injection system usually uses multiple injectors to control the fuel injection amount of the engine, and the most common injector type is the CRDI Injector Nozzle.
1.CRDI Injector Nozzle DLLA159P2204 Quality Control
- Injector Nozzle Testing
All parts of the injector nozzle are subjected to precision testing, high temperature testing, low temperature testing, withstand pressure testing, leakage testing, durability testing, and various working conditions testing.
- Injector Nozzle Inspection
The factory inspection of the injector nozzle is undergone full inspection, random inspection, and batch inspection three inspections. Different brands of test benches are used to test the same injector nozzle for a total of no less than three times for factory inspection, and the fuel injector installation testing environment are progressed in dust-free workshop.
