Truck Engine Parts Common Rail Fuel Injector Nozzle 0445110690 E049332000109 Diesel Injector for Foton 4jb1 Engine

This heavy-duty electronically controlled common-rail diesel fuel injector assembly (Part ID: 0445110690 / 0 445 110 690; common OE cross-references include 0986435282, 1100100A-ED01, 1100100AED01, etc.) is precision-engineered. Designed for the GW4D20/4D20 series 2.0T diesel engine platform, it is widely used in pickup trucks and SUVs such as the Wingle 5, Wingle 6, Wingle 7, Haval H5, and Haval H6. As a core component of 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—triggered by millisecond-level electrical signals—to ensure thorough mixing with intake air for optimal combustion.

The component is 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 mechanics will notice immediate improvements: crisp, reliable cold starts and quiet, vibration-free idling. Whether climbing steep slopes, navigating stop-and-go traffic, or cruising long distances, the throttle response is sharp and sensitive, and acceleration is robust yet smooth. Additionally, it reduces black smoke emissions, delivering satisfactory fuel efficiency and a stable, 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.

Pickup truck operations (dual-purpose passenger/cargo) and engineering inspection tasks: Pickup trucks operating at construction sites, in mining areas, and on rural roads frequently face the challenges of fully loaded hill climbs and harsh terrain. When vehicles exhibit sluggish acceleration, difficult cold starts, or increased black exhaust smoke, maintenance personnel can replace the unit with this electronically controlled common rail injector. Post-installation, fuel delivery is smooth and low-RPM torque is abundant, enabling the vehicle to easily handle heavy loads and steep inclines. Passenger SUV & Long-Distance Commuting: Diesel SUVs used for daily city commuting or long-distance inter-provincial travel demand high standards for engine smoothness and fuel efficiency. When owners notice significant idling vibration, sluggish acceleration, or increased fuel consumption, mechanics can install a complete set of high-precision fuel injector valves. Precise fuel atomization restores quiet, smooth engine operation, ensuring a comfortable driving experience.

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 input 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 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 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 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 service handled?
A: We offer a 12-month warranty. In the event of a performance failure due to non-human factors during the warranty period, we provide rapid replacement or technical support to ensure a worry-free experience.
