As request or standard packing |
| 1. High-pressure fuel storage & pressure stabilization (Accumulator Function) |
| It stores high-pressure diesel fuel delivered by the high-pressure pump. Its internal buffer volume eliminates sharp pressure fluctuations caused by periodic pump oil delivery and injector intermittent injection. It maintains stable constant rail pressure (1300–1600 bar) regardless of engine speed or load, which is the core advantage of common rail technology over traditional mechanical injection systems. |
| |
| 2. Equalized fuel distribution for all cylinders |
| The rail body is equipped with 6 independent high-pressure outlets. It evenly distributes stabilized high-pressure fuel to each cylinder’s fuel injector, ensuring every injector gets identical fuel pressure and supply volume. This guarantees balanced combustion power across all 6 cylinders, avoiding engine shaking, uneven output and black smoke. |
| |
| 3. Real-time pressure feedback for ECU control |
| A built-in rail pressure sensor transfers real-time internal fuel pressure signals to the engine ECU. The ECU adjusts the high-pressure pump’s fuel delivery volume according to the feedback signal to automatically raise or lower rail pressure to match idle, acceleration, heavy digging and other working conditions, optimizing power and fuel consumption. |
| |
| 4. Overpressure safety protection |
| Equipped with integrated pressure limiting valve. When fuel pressure exceeds the safety threshold due to pump failure or sensor malfunction, the valve automatically opens to release excess high-pressure fuel back to the low-pressure fuel circuit, preventing rail cracking, injector burst and pipeline rupture caused by ultra-high pressure. |
| |
| 5. Single-cylinder fault isolation via flow limiters |
| Each injector port installs a flow limiter. If one injector gets stuck open and continuously leaks fuel, the limiter will cut off fuel supply to this single cylinder independently. It stops massive fuel loss, avoids engine runaway, and protects the whole common rail pressure system from collapse. |
| |
| 6. High-pressure seal & pressure bearing carrier |
| Made of high-strength alloy steel, it withstands extreme long-term high-pressure load. It provides precise sealing mounting interfaces for pressure sensor, limit valve and high-pressure pipelines, preventing high-pressure diesel leakage that would trigger fire risks and power loss. |
