This electronically controlled high-pressure common-rail diesel fuel injector assembly (Part ID: 0445110304 / 0 445 110 304; common cross-references and OE interchange codes include 0445110305, 0986435183, 55577662, 55580690, etc.) is precision-engineered. It is designed for the A13DTE / A13DTC / A13FD 1.3 CDTI / 1.3 JTD inline-four diesel engine family, widely used in models such as the Corsa, Astra, Combo, Meriva, and various light commercial vans. As a core actuator within the fuel supply system—responsible for controlling diesel atomization quality and pulse injection timing—it precisely meters high-pressure diesel and rapidly disperses it into ultra-fine particles in response to millisecond-level electrical signals, thereby promoting thorough mixing and combustion with the intake air.
The component is designed and manufactured to standards emphasizing "micro-level precision fit" and "millisecond-level rapid response." The core control valve spool and needle valve assembly are crafted from aerospace-grade, hardened special alloy steel, featuring ultra-high-precision geometric grinding and low-friction polishing. A dense, ultra-hard surface coating effectively prevents internal scratching and pressure loss caused by diesel impurities. Upon installation, drivers and technicians will notice immediate improvements: crisp, clean cold starts; quiet and smooth idling with minimal noise and vibration; and responsive, agile throttle control during steep climbs, stop-and-go driving, or long-distance cruising. It delivers robust, smooth acceleration and reduced black smoke emissions, ensuring satisfactory fuel efficiency and a refined driving experience.
Standardized smart manufacturing and rigorous quality control directly from the source factory. Cost-effective sourcing by eliminating intermediary markups. 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 crossovers frequently undergo stop-and-go driving in city 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 idle 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 accelerator is lightly pressed.
Light-duty passenger/cargo transport and intercity business/logistics delivery scenarios: Small logistics box trucks and commercial MPVs 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 (km/L), and ensures timely deliveries.
Q: Can the product be used immediately after installation, or is a correction code required?
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, year-round stock of this model. Standard orders are 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 shipment?
A: All fuel injectors undergo assembly in a Class 100 cleanroom environment and 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pilot 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 your peace of mind.
