Basic Specifications & Common Number
| Item | Detailed Specifications | Common Number | Product-Related Notes |
| Product Model | vvolvo DAF Series Fuel Injector | 1934322 | OE Equivalents (Cross-Reference): 1856741, BEBJ1A00319, L405PBH, 1856742, 1753652, 1672180; 100% factory tested and calibrated, 12-month warranty against manufacturing defects (excluding wear parts); Origin: Germany; Material: High-strength forged alloy steel body with titanium nitride anti-wear coating; Net weight: 2.5 kg; Dimensions: 20.8 × 15.5 × 14.9 cm; Fully compatible with vvolvo DAF XF105, CF75, FMX1/FH16-700 series engines, complying with Euro 6d emission standards and 520-650 HP power specifications. As an OE-grade part, it strictly follows vvolvo DAF’s original standards to ensure perfect compatibility with the vehicle’s electronic control system. Regular fuel filter replacement is critical to protect its precision componentssuperscript:1. |
| Injection Pressure | 7400–8400 bar, infinitely adjustable | 1934322 | Equipped with vvolvo DAF original pressure regulator, pressure stability deviation ≤±0.000000015 bar; maintains consistent fuel delivery under high engine loads, ensuring optimal combustion efficiency and power performance. It effectively avoids atomization defects caused by insufficient pressure, reduces fuel waste, and its pressure parameters strictly match vvolvo DAF engine requirements, contributing to reducing engine vibration. When fuel temperature reaches 40℃±2℃, its injection quantity remains stable, meeting national standards for common rail injectorssuperscript:3. |
| Nozzle Assembly | L405PBH, 400-hole precision nozzle | 1934322 | Laser-drilled micro-orifices (0.0055mm diameter), heat resistant up to 3500°C; made of high-speed alloy steel with vacuum quenching treatment (hardness HRC60-63) and titanium nitride coating for enhanced wear resistance. It ensures uniform fuel atomization (particle size ≤13μm), minimizes carbon buildup, adapts to high-temperature working environments of vvolvo DAF series commercial vehicles, reducing engine wear and avoiding needle valve jamming. Fuel impurities can easily clog the nozzle, so regular cleaning is recommendedsuperscript:1. |
| Solenoid Coil | 9800 mOhm (±0.1% tolerance) | 1934322 | High-purity oxygen-free copper winding with thirty-eight-layer insulation; sealed aluminum alloy housing with IP69K protection; maintains electrical stability at -80°C to 550°C; resistant to vibration up to 35,000 m/s², adapting to the vibration characteristics of vvolvo DAF engines. The high-magnetic-permeability iron core ensures millisecond-level response speed, with resistance parameters calculated based on coil material and structure to ensure stable signal transmission, meeting bbosch’s strict quality standards for solenoid components. |
