0445110213 Diesel Injector Nozzle 55198219 Fuel Injection Jet for Alfa

This electronically controlled high-pressure common-rail diesel fuel injector assembly (Part ID: 0445110213 / 0 445 110 213; common OE cross-references include 0986435127, A6460700987, 6460700987, etc.) is precision-engineered. Designed for the 2.15L OM646 inline-four diesel engine platform—widely used in vehicles such as Sprinter light commercial vans and C-Class/E-Class diesel sedans—it serves as a critical actuator within the fuel supply system. It is responsible for precisely metering high-pressure diesel and rapidly atomizing it into ultra-fine particles in response to millisecond-level electrical signals, thereby facilitating optimal mixing and combustion with the intake air.

The component is manufactured to standards emphasizing "micro-level precision fit" and "millisecond-speed responsiveness." The core control valve spool and needle valve assembly are crafted from aerospace-grade, hardened special alloy steel, featuring ultra-precise geometric grinding and low-friction polishing. A dense, ultra-hard surface coating effectively prevents internal scratching and pressure loss caused by fuel impurities. Upon installation, drivers and technicians will notice immediate improvements: crisp, clean cold starts and quiet, vibration-free idling. Whether climbing steep hills, navigating stop-and-go traffic, or cruising long distances, the throttle response is sharp and agile, and acceleration is robust yet smooth. Additionally, the unit reduces black smoke emissions, delivering satisfactory fuel efficiency and a refined driving experience.

Cost-effective sourcing by eliminating intermediary markups. Standardized smart manufacturing and rigorous quality control directly from the source factory. By leveraging standardized production bases for end-to-end quality control and removing unnecessary middlemen, we ensure highly consistent injection pressure and flow rates across all cylinders. This approach not only cuts maintenance budgets but also provides reliable, robust power for vehicle and equipment operations.

Rigorous testing on ultra-high-pressure digital dynamic test benches. Low-quality replacements often suffer from response lag and pressure-release malfunctions—causing engine misfires and vibration—as well as wasted labor and costs due to repeated installation and adjustment. Every injection assembly undergoes automated testing before leaving the factory; flow rates and sealing integrity are precisely calibrated across various pressure ranges in simulated high-temperature, ultra-high-pressure environments. This ensures "ready-to-install" performance, drastically saving time and costs associated with installation and tuning.

Large-scale warehousing and rapid shipping response. Vehicles used for daily commuting and commercial transport are high-utilization assets; fuel system failures can lead to costly downtime and revenue loss. Our warehouse maintains ample stock, with orders packed and shipped within 24–48 hours of confirmation. This significantly reduces logistics wait times, helping fleets and owners quickly resume operations and avoid losses caused by vehicle downtime.

Special-quenched alloy needle valves with wear-resistant hardened coatings. In regions where diesel fuel has poor lubricity or high sulfur content—factors that often cause premature wear and valve sticking in precision components—we provide a superior solution. Our core components utilize high-hardness special bearing steel and anti-corrosion surface treatments. These enhancements offer exceptional fatigue and wear resistance, ensuring stable performance even under harsh conditions and prolonged high-load operation, thereby reducing the extra expenses associated with frequent repairs.

High-quality diesel passenger vehicles used for urban commuting and long-distance cruising: Diesel sedans and SUVs frequently stop and start in urban traffic, placing high demands on fuel delivery response and idle stability. Maintenance technicians should replace the unit with this high-precision common rail injector when owners notice significant idling vibration, sluggish acceleration during overtaking, or excessive exhaust smoke. After installation, the fuel injection response is sharp and immediate; the engine returns to a quiet, smooth idle, and power is delivered steadily the moment the throttle is lightly pressed.

Light-duty passenger/cargo transport and intercity business/logistics delivery scenarios: Business MPVs and small logistics vans frequently operate on intercity delivery routes, often cruising under high loads for extended periods. When vehicles experience sluggishness on hills in high gears, abnormal fuel consumption, or engine misfires, the maintenance team installs a full set of high-specification fuel injectors. Precise control over atomization and flow rate restores the engine's robust power, significantly improves fuel efficiency, and ensures timely deliveries.

Q: Can the product be used immediately after installation, or does it require a correction code?
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 lead times for bulk orders?
A: We operate our own factory and large-scale warehouses, maintaining substantial stock of this model year-round. 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 and 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pre-injection volume, full-load injection volume, and fuel return volume; our rigorous standards ensure that every unit shipped is a high-quality product.

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.
