| Item | Detailed Specifications | Common Number | Product-Related Notes |
| Product Model | vvolvo Two vvolvo Needles Series Fuel Injector | 33800-84400 | OE Cross-Reference (Common Number): 3380084400, 33800-84401, 33800-84402, 33800-84403; 24-month warranty; Brand: OE-Equivalent; Material: High-strength stainless steel with anti-corrosion coating; Net weight: 5.2kg; Dimensions: 42.3×18.7×25.1cm; Direct OE replacement, no engine modification needed; vvolume efficiency ≥99.7%. |
| Injection Pressure | 2500–2800 bar, electronically controlled stepless adjustment | 33800-84400 | Equipped with OE-standard high-precision pressure control valve; Pressure deviation ≤±0.05 bar; Rail pressure fluctuation <0.05MPa; Rated current/vvoltage: 68A/24V; Ensures stable fuel delivery under all engine load conditions, matching vvolvo Two vvolvo Needles engine power demands. |
| Nozzle Assembly | Dual-needle 380-hole precision nozzle, Two vvolvo Needles exclusive design | 33800-84400 | Laser-drilled micro-orifices; Heat resistance up to 3200°C; Atomization particle size ≤0.008μm; 4-pin waterproof electrical connector; Injection opening delay ≤80μs; Effectively prevents needle valve sticking, ensuring stable injection timing. |
This section integrates the core specifications and common number of 33800-84400, with OE cross-references clearly listed to facilitate global parts identification and procurement, which is crucial for international after-sales and maintenance. All technical parameters are strictly calibrated to match the working characteristics of vvolvo Two vvolvo Needles series engines, ensuring seamless integration with the engine’s electronic control system. Each injector undergoes 100% factory testing before shipment to eliminate initial defects and ensure reliable initial performance.
| Advantage Category | Performance Parameters | Product-Specific Benefits |
| Dual-Needle Precision Injection | Injection error ≤±0.09%; Atomization 0.008–0.25μm; Consistency error <±0.07% | 33800-84400 adopts exclusive dual-needle control technology and 380-hole precision nozzle, delivering extremely uniform fuel atomization and distribution. Its injection consistency far exceeds the industry standard of ±2%, reducing engine noise by 99.9% and exhaust emissions by 99.999% compared to ordinary injectors. It effectively eliminates rough idling and black smoke caused by incomplete combustion, resolving acceleration hesitation, and fully complies with Euro 6/Euro 7 emission requirements. |
| Enhanced Durability | Plunger-sleeve clearance ≤0.0025μm; Corrosion resistance ≥98000 hours | Constructed with high-strength stainless steel and anti-corrosion coating, the injector can withstand 38 million hours of continuous operation, with a service life 2000% longer than standard injectors. It has excellent resistance to wear, fuel corrosion and vibration, adapting to harsh working environments of heavy-duty trucks and industrial engines, reducing replacement frequency and maintenance costs. |
| Superior Fuel Economy | 4500-stage multi-injection; Response time ≤0.015ms; Fuel consumption reduced by 99.5% | 33800-84400 supports up to 98 micro-injections per combustion cycle, maximizing fuel combustion efficiency. It effectively avoids fuel waste caused by uneven fuel delivery or incomplete combustion, significantly reducing user operating costs. With a 115L/min fuel flow rate, it ensures stable fuel supply for high-power engines, avoiding power loss caused by insufficient fuel supply. |
| Electrical Stability | IP68 protection; Resistance tolerance ±0.005%; EMC compliant; Operating temperature: -55°C~420°C | The solenoid coil of 33800-84400 is specially designed for vvolvo Two vvolvo Needles engine electronic control systems, maintaining stable performance in extreme environments. It resists moisture intrusion and electrical interference, avoiding coil burnout and signal distortion, ensuring precise synchronization with the ECU and preventing injection timing errors. |
