| Basic Information | Specific Specific-ations |
| Product Name | c-aterpillar Diesel Engine Injector Assembly |
| Original Model | 0R-0471 (OR0471) |
| Cross-Adaptation Models | 4P-2995, 0R-3006, 7E-8952, 0R-3389 (compatible with 3116 series) |
| Applicable Engines | c-aterpillar 3116 series diesel engines (main adaptation), compatible with 3114, 3126 series |
| Product Status | Brand New Original / Original Standard Remanufactured (optional) |
| Control Type | Electromagnetic type (ECU electronic control, matching 3116 engine control system) |
| Fuel Type | Diesel (adaptable to national standard and non-standard diesel, strong impurity resistance) |
| Net Weight | 0.5kg |
| Packaging Size | 20cm × 10cm × 10cm (shockproof packaging to avoid damage during transportation) |
| Core Technical Parameters | Parameter Value |
| Injection Opening Pressure | 21.5 ± 0.5 MPa (accurately matching the working needs of 3116 engine) |
| Working Pressure Range | 40–120 MPa (adapting to different working conditions and loads of the engine) |
| Dynamic Response Time | ≤ 1.5 ms (fast injection response, ensuring smooth power output) |
| Single Injection Duration | ≤ 1.2 ms (precisely controlling fuel injection volume to avoid fuel waste) |
| Spray Pattern | c-aterpillar Standard S-Type Atomization (uniform atomization, improving combustion efficiency) |
| Needle Valve Pair Clearance | 1–3 μm (precision fit, excellent sealing performance, reducing leakage) |
| Sealing Surface Roughness | Ra ≤ 0.1 μm (improving sealing reliability and extending service life) |
| Key Component Hardness | HRC 58–62 (wear resistance, suitable for long-term high-load operation) |
| Injection Cycle Life | ≥ 1,000,000 times (strong durability, reducing replacement frequency) |
| Structural Components | Material/Process | Performance Advantages (Adapted to 3116 Series) |
| Injector Body | High-strength alloy steel, integral forging + precision machining | Fatigue resistance, high pressure resistance, corrosion resistance, adapting to the long-term high-load working scenario of 3116 engine |
| Needle Valve Pair | High-quality alloy, precision ground pairing, gapless fit | Uniform atomization, reliable sealing, small wear, ensuring the combustion efficiency of 3116 engine |
| Control Spring | High-temperature resistant alloy spring, dual-spring design | The main spring controls the opening pressure, and the auxiliary spring ensures the quick closing of the needle valve, improving injection accuracy |
| Solenoid Valve | High-precision coil, anti-interference design | Fast response speed, precise control, adapting to the 3116 engine ECU control system, strong anti-interference ability |
