This electronically controlled high-pressure common-rail diesel fuel injector assembly (Part ID: 0445110479 / 0 445 110 479; common OE cross-references include 13537810702, 781070202, 13537810703, 0445110478, 0986435242, etc.) is precision-engineered for the N47/N47D20 and N57 series 2.0D/3.0D inline diesel engine platforms. It is widely fitted across various models, including the 1 Series (F20), 3 Series (E90/F30), 5 Series (F10/F11), 7 Series (F01), X1, and X3. As a core actuator in the high-pressure common-rail system responsible for precisely controlling diesel atomization quality and pulse injection timing, it rapidly breaks down high-pressure diesel into ultra-fine particles under millisecond-level electrical signal control, thereby facilitating thorough mixing and combustion with the intake airflow.
The component is manufactured to standards featuring "micron-level fit tolerances" and "millisecond-level rapid response." Its internal control valve spool and needle valve assembly are crafted from premium aerospace-grade hardened bearing steel, utilizing ultra-high-precision geometric grinding and low-friction polishing. The surfaces feature a high-density, ultra-wear-resistant hardened coating, effectively preventing internal scratches and pressure-loss-related sticking caused by diesel impurities.
Problem Solved: Addresses issues caused by intermediary agents, such as excessive component tolerances, uneven fuel injection across cylinders, and risks of high-pressure leaks.
Value Delivered: Leverages a standardized production base for end-to-end quality control and eliminates unnecessary markups; ensures highly consistent injection pressure and flow rates across cylinders, reducing maintenance budgets while providing reliable power for vehicle and equipment operation.
Problem Solved: Mitigates issues common to low-quality replacements—such as response lag, pressure loss, or sticking valves causing engine misfires and vibration—as well as the wasted time and expense of repeated installation and adjustment.
Value Delivered: Every injection component undergoes automated testing before leaving the factory; flow rates and sealing performance are precisely calibrated across various pressure ranges in environments simulating real-world high-temperature, ultra-high-pressure conditions. This ensures "ready-to-install" performance, drastically saving time and costs associated with installation and tuning.
Problem Solved: Addresses the costly downtime and financial losses incurred when high-utilization vehicles—essential for daily commuting or commercial transport—are sidelined due to fuel system failures.
Value Delivered: The warehouse maintains ample stock year-round; orders are packed and shipped within 24–48 hours of confirmation. This significantly shortens logistics wait times, helping fleets and vehicle owners quickly resume operations and avoid losses associated with vehicle downtime.
Problem Addressed: Addresses issues in certain regions where poor diesel lubricity and sulfur impurities tend to cause premature wear of precision mating parts and valve spool seizure.
Value Delivered: Core mating parts utilize high-hardness specialty bearing steel and surface anti-corrosion treatments, significantly enhancing fatigue and wear resistance; this ensures stable performance even under harsh conditions and prolonged high-load operation, thereby reducing additional costs associated with frequent disassembly and repair.

High-quality diesel passenger vehicles for urban commuting and long-distance cruising: Diesel sedans and SUVs frequently start and stop in urban traffic, placing extremely high demands on fuel delivery response speed and idle stability. When vehicle owners notice significant idling vibration, sluggish acceleration during overtaking, or excessive exhaust smoke, maintenance technicians should promptly replace the unit with this high-precision common-rail fuel injector. Post-installation, fuel injection response becomes swift and agile, engine idling returns to a quiet and smooth state, and power is delivered steadily the moment the accelerator is lightly pressed.
Light-duty passenger and cargo transport, as well as intercity business/logistics delivery scenarios: Business MPVs and small logistics vans frequently operate on intercity delivery routes, often maintaining high-load cruising speeds for extended periods. When vehicles exhibit sluggishness climbing hills in high gears, abnormal fuel consumption, or engine misfires, the maintenance team should install a full set of high-specification fuel injection valves. Precise control over atomization and flow rate restores the engine's robust power output, significantly improves fuel efficiency per 100 kilometers, and ensures timely delivery.
Q: Can the product be used immediately after installation, or does it require a correction code input?
A: Each fuel injector is assigned a unique flow correction code (IMA/QR code) during factory testing. We recommend using a diagnostic tool to program this code into the engine control unit (ECU) after installation to achieve optimal fuel efficiency and smooth operation.
Q: What are the stock levels and shipping lead times for bulk orders?
A: We operate our own factory and large-scale warehouses, maintaining substantial, year-round inventory for this model. Standard orders are typically packed and shipped within 24–48 hours, while bulk orders can be quickly scheduled for production.
Q: How are product quality and performance ensured before leaving the factory?
A: All fuel injectors undergo assembly in a Class 100 cleanroom environment and 100% bench testing across all operating conditions. Tests cover critical parameters such as sealing integrity, pilot injection volume, full-load injection volume, and fuel return volume; rigorous standards ensure that every unit shipped is of premium quality.
Q: What is the warranty period, and how is after-sales support handled?
A: We offer a 12-month warranty. Should a performance failure occur due to non-human factors within the warranty period, we provide rapid replacement or technical support to ensure a worry-free experience.
