Diesel Fuel Injector 33800-2A800 0445110410 Injector Assembly for Hyundai/KIA 1

This heavy-duty electronically controlled common-rail diesel fuel injector assembly (Part ID: 0445110410 / 0 445 110 410; common OE cross-references include 0986435252, 1100100-ED01, 1100100ED01, 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, Haval H5, and Haval H6. 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 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. The surface is treated with a dense, ultra-hard coating to effectively prevent internal scratching and pressure loss caused by diesel impurities. Upon installation, drivers and mechanics will notice cold immediate improvements: crisp, clean starts and quiet, vibration-free idling. Whether steep climbing slopes, frequently stopping and starting, or cruising long distances, the throttle response is sharp and sensitive, and acceleration is robust yet smooth. Additionally, the unit reduces black smoke emissions, delivers 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 warehouse 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.
