166003978r Ejbr02101z Ejbr04101d New Enqine Diesel Fuel Injector for Re-nault 28232242

This high-pressure electronically controlled common rail fuel injection valve body assembly (original equipment manufacturer (OEM) part number: 166003978R / 16 60 039 78R; common OE cross-reference and interchangeable identification codes include 166006212R, 0445110480, 0445110780, 0986435251, etc.) is primarily matched with K9K/R9M series 1.5 dCi and 1.6 dCi inline four-cylinder diesel power platforms and is widely installed in crossover SUVs, light commercial vehicles, compact buses, and multi-purpose trucks. As a micro-metering and ultra-fine spray actuator in the fuel supply system, it is responsible for accurately metering high-pressure diesel fuel and rapidly dispersing it into micron-level atomized particles under microsecond-level electrical signal commands, promoting efficient and complete mixing and combustion of fuel and intake airflow.

The product adheres to a precision design process of "microscopic ultra-fine atomization and millisecond-fast response." The internal needle valve assembly and control valve core are made from specially hardened alloy steel, combined with high-precision geometric grinding and low-friction polishing. The surface is coated with a high-density, ultra-wear-resistant DLC hardened coating, effectively preventing early erosion and jamming caused by diesel impurities. After the parts are installed, drivers and mechanics will experience a clear and intuitive improvement: crisp and quick cold starts in the morning, and reduced low-speed idling vibration; in urban driving, steep incline, or long-distance highway cruising, the accelerator pedal response is firm and sensitive, acceleration is smooth and powerful, and exhaust smoke is significantly improved, resulting in satisfactory fuel efficiency control and smooth handling.

Directly manufactured in our own factory. This effectively reduces procurement costs by addressing the risks of excessive tolerances in parts, uneven fuel supply to cylinders, and high-pressure leakage associated with third-party OEM distribution chains. Leveraging standardized production bases for precise end-to-end control, eliminating intermediate markups, and ensuring highly consistent fuel injection volumes across all cylinders, this reduces maintenance budgets while providing robust and reliable power for vehicle operation.

Strict quality control using a full-condition ultra-high pressure digital dynamic test bench. Addressing the issues of response delays, pressure relief jamming leading to engine misfires and vibrations, and wasted time and money due to repeated disassembly and adjustment caused by low-quality parts, each injection component undergoes automated testing before leaving the factory. Under simulated high-temperature and ultra-high-pressure conditions, the fuel injection volume and sealing performance across different pressure ranges are precisely calibrated, ensuring immediate usability upon installation and significantly reducing time and costs associated with equipment disassembly and adjustment.

Large-scale warehousing ensures constant availability and rapid delivery. This is crucial for daily commuting and commercial transport vehicles, which are high-attendance productivity tools, and the costly delays and lost work due to fuel system failures. Our warehousing center maintains ample stock of best-selling specifications year-round. Once an order is confirmed, we respond quickly and prioritize packing and shipping within 24-48 hours, significantly shortening the logistics and delivery cycle. This helps fleets and owners quickly restore equipment availability and effectively avoids losses due to downtime.

Special hardened alloy needle valves with corrosion-resistant hardened coating. Addressing the issue of premature wear and valve core seizure caused by differences in diesel lubricity and sulfur content in different regions, the core valve assembly uses high-strength special bearing steel and a surface corrosion-resistant hardening treatment, greatly improving fatigue resistance and wear resistance. It maintains stable performance even in harsh environments and under prolonged high-load operation, avoiding the additional costs of frequent disassembly and repair.

High-Frequency Urban Commuting and Daily Driving Conditions of Multi-Purpose Diesel Vehicles: Diesel SUVs and crossovers frequently start and stop in stop-and-go urban traffic, requiring extremely high fuel supply response speed and idle smoothness. When owners notice severe idling vibration, sluggish acceleration response, or excessive exhaust smoke, maintenance personnel should promptly replace this high-precision common rail injector. After the replacement, the fuel injection response is sensitive and rapid, the engine idles quietly and smoothly, and power is delivered instantly with a light touch of the accelerator.

Light passenger and freight transport and intercity logistics delivery scenarios: Light vans and passenger MPVs are used for intercity cargo delivery, and the vehicles operate under high-load cruising conditions for extended periods. When vehicles experience difficulties climbing hills in high gears, abnormally increased fuel consumption, or engine misfires, the repair team replaces the entire set of high-specification fuel injection valves. Precise atomization and flow control allow the engine to unleash abundant power again, significantly improving fuel efficiency per 100 kilometers and ensuring timely delivery.

Q: Can I use the product directly after installation? Is it necessary to enter a correction code?

A: Each injector has a unique flow correction code (IMA/QR code) generated during factory testing. It is recommended to use a diagnostic tool to flash the correction code into the engine ECU after installation to achieve optimal fuel efficiency and smoothness.

Q: What are the inventory and delivery times for bulk purchases?

A: We have our own factory and large warehouse, maintaining a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can be quickly scheduled for production.

Q: How do you guarantee the quality and performance of your products before they leave the factory?

A: All injectors undergo assembly in a Class 100 cleanroom and 100% full-condition bench testing, covering key indicators such as sealing, pre-injection volume, full-load injection volume, and return oil volume. These stringent testing standards ensure that they are high-quality products from the outset.

Q: How long is the warranty period? What about after-sales service?

A: We offer a 12-month warranty period. If a performance failure occurs within the warranty period due to non-human factors, we provide rapid replacement or after-sales technical support to ensure your peace of mind.
