BOSCH Common Rail Pressure Relief Limiter Valve 1110010015 FOR WEICHAI WP10 WP12 WP13 ENGINE CUMMINS ISME ISLe ISB ENGINE
Common Faults and Repair Tips
1. Engine Lacks Power / Speed Limiting: The pressure relief valve fails to maintain pressure, causing fuel to flow directly back to the fuel tank. This prevents the common rail from building up the required pressure; the system then triggers a "Rail Pressure Relief Valve Open" fault code and limits the engine speed.
2. Hard Starting (Hot Engine): Starting the engine requires the instantaneous buildup of rail pressure reaching several hundred MPa. If internal wear causes leakage within the 1110010015 valve, fuel pressure escapes through the return port during the start-up attempt, making it difficult to start the engine.
3. Inspection Method: Disconnect the valve's fuel return line and observe while starting the engine (or cranking the starter). Under normal conditions, the valve should not leak fuel. If fuel sprays or drips continuously from the return port immediately upon cranking, the pressure relief valve is damaged and must be replaced.
Bill of Materials (BOM) for Common Rail Pressure Relief Valve Replacement
| Category | Part Number / Spec | Part Name (EN) | Standard Qty | Maintenance & Tech Notes |
|---|---|---|---|---|
| Core Actuator | 1110010015 | BOSCH Common Rail Pressure Relief Valve (PLV) | 1 PC | Core Replacement Part. Must use genuine BOSCH parts to withstand 1600 bar impulse pressure. |
| High-Pressure Seal | - | Crush Washer (Copper / Steel Seal) | 1 PC | Must be replaced with new. Usually included with the valve. One-time compression seal; reuse will cause fuel leakage. |
| Fuel Return Line | Vehicle-specific | Fuel Return Rubber Hose | 1 PC | Rubber hoses harden over time. Often cracks during disassembly; concurrent replacement recommended. |
| - | Hose Clamp / Spring Clip | 1-2 PCS | Ensures tight sealing in the low-pressure return zone to prevent fuel odor or weeping. | |
| Contamination Guard | 1457431713 (Example) | High-Efficiency Fuel Filter (with Water Separator) | 1 SET | Strongly Recommended. Valve sticking/wear is mostly caused by fuel moisture or debris. Without clean filters, the new valve may fail prematurely. |
| Chemicals & Flush | - | BOSCH Common Rail System Cleaner | 1 CAN | Used to thoroughly flush metallic shavings and dirt out of the common rail threads before installing the new valve. |
