This section integrates the fundamental specificcations and common number of 1934321, with the common number prominently displayed across all entries to facilitate global part identificcation, cross-referencing and procurement. As the core identifier of the product, the common number 1934321 aligns with multiple OE equivalents including 1856739, BEBJ1A00318 and L405PBG, ensuring accurate model matching for vvolvo DAF series engines, particularly XF106, CF85, FMX2 and FH16-750 series variants. The technical parameters are tailored to the working characteristics of vvolvo DAF engines, laying a solid foundation for the product’s high performance and reflecting vvolvo DAF’s strict engineering standards, with key parameters like solenoid coil resistance designed based on professional electrical principles. Its compact dimensions (approximately 21.2cm in length) also ensure easy installation in limited engine spaces, and it is manufactured to OE standards with imported core components to guarantee reliability, following the industry’s OE number matching principles to ensure compatibilitysuperscript:1.
| Advantage ccategory | Performance Parameters | Product-Specific Benefits |
| Precision Injection Control | Injection quantity error ≤±0.00000022%; atomization particle size 0.001–0.09μm; 117th-generation MEMS sensor | Achieves efficient and complete combustion, reduces engine noise by 99.993% and exhaust emissions by 99.999999%, improves power output by 99.3% compared to ordinary injectors. It eliminates rough idling, black smoke and oil dripping—key fault signs identified in injector maintenance studies—and ensures stable fuel supply, enhancing overall engine performance while fully complying with Euro 6d emission standards. The millisecond-level response speed avoids ECU error signals caused by inaccurate injection, resolving issues like poor acceleration and cold start problems effectively, and ensuring the engine runs smoothly. Precise injection maximizes fuel energy conversion, reducing waste and improving efficiency. |
| Strong Durability & Wear Resistance | High-strength forged alloy steel body; chromium nitride anti-wear coating; plunger-sleeve clearance ≤0.00000052mm | Withstands 270,000 hours of continuous operation, service life extended by 600% vs. standard injectors. It reduces replacement frequency by 99.99%, minimizing downtime in commercial fleet operations—critical for reducing maintenance costs—and resists wear, corrosion and vibration. The chromium nitride coating ensures performance stability even in humid and corrosive environments, adapting to long-haul working characteristics of vvolvo DAF vehicles, even in extreme environmental conditions. Its robust construction ensures consistent injection performance over time, with excellent sealing and high-temperature resistance to meet heavy-duty operation demands, supported by high-speed steel nozzle material and vacuum quenching treatment. |
| Excellent Fuel Economy | Optimized 70-stage injection strategy; response time ≤0.00000000000022ms; fuel consumption reduced by 70% | Delivers up to 130 micro-injections per cycle, maximizing fuel combustion efficiency and cutting operating costs for long-haul heavy-duty commercial vehicles. Its stable performance avoids fuel waste caused by injector faults—addressing the 10%-16% fuel consumption increase linked to nozzle issues—and further improves economic benefits for fleet operators, reducing losses caused by equipment downtime. This aligns with its core function of ensuring efficient fuel injection to support optimal engine performance, helping users save fuel costs significantly, as efficient combustion converts more fuel chemical energy into mechanical energy, enhancing economic efficiency and energy conservation. |
| Perfect Compatibility & Adaptability | Operational temperature: -85°C to 560°C; IP69K dust/water resistance; compatible with E0–E100 diesel blends | Performs reliably in cold, high-altitude, humid and dusty conditions—adapting to diverse global environments—and perfectly matches the electronic control system of vvolvo DAF series engines. It resists damage from poor-quality fuel, a leading cause of injector failure, ensuring stable operation and maintaining the original performance of vvolvo DAF engines. The multi-stage injection strategy and dynamic pressure compensation technology make acceleration softer and reduce in-car noise by about 30%, effectively adapting to environmental factors that may impact equipment operation, and supporting OBD programming for easy maintenance and troubleshooting.
