Fuel Injector EJBR04001D 166009384R Ejbr01801z 28232248 for Re-nault 1.5 Dci

This high-pressure electronically controlled common rail fuel injection valve body assembly (part number: 166009384R; common OE cross-reference and interchangeable identification numbers include 166006212R, 166001137R, 1660000Q1V, H8201100113, etc., mainly matched with the 1.5 dCi K9K series 1.5L inline four-cylinder diesel power platform, widely installed in light passenger cars, urban compact SUVs, commercial MPVs, and small logistics vans, etc.) is meticulously crafted. As the micro-metering and ultra-fine spray execution unit in the entire fuel supply system, it bears the heavy responsibility of accurately metering high-pressure diesel fuel and rapidly dispersing it into ultra-fine atomized particles under microsecond-level electrical signal commands, promoting full mixing and combustion of fuel and intake airflow.

The product adheres to the precision standards of "microscopic ultra-fine atomization and millisecond-fast response." Internal needle valve components and control valve cores are made from carefully selected aerospace-grade quenched special alloy steel, combined with ultra-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 very clear and intuitive improvement: crisp and rapid cold starts in the morning, and the severe vibration at low-speed idling has subsided and become smooth; in urban driving, steep incline, or highway cruising and overtaking, the accelerator pedal response is firm and sensitive, acceleration is smooth and powerful, and exhaust smoke is significantly improved, resulting in satisfactory fuel consumption control and a smooth driving experience.

• Advantages: Intelligent manufacturing in a physical factory and standardized production throughout the entire process.

  Problems Solved: Effectively reduces procurement costs by addressing issues such as excessive tolerances in parts manufacturing and distribution chains, uneven fuel supply to cylinders, and potential high-pressure leaks.

  Value Gained: Utilizing a standardized production base for precise end-to-end control, eliminating intermediary markups, and ensuring highly consistent fuel injection across all cylinders. This reduces maintenance budgets while providing robust and reliable power for vehicle operation.

• Advantages: Rigorous quality inspection using a full-condition ultra-high-pressure digital dynamic test bench.

  Problems Solved: Addresses issues such as response delays caused by low-quality parts, engine misfires and vibrations due to pressure relief jamming, and wasted time and money due to repeated disassembly and adjustment.

  Value Gained: Each injection component undergoes automated testing on a test bench 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 saving time and costs associated with equipment disassembly and adjustment.

• Advantages: Large-scale warehousing with readily available stock for rapid delivery response.

  Problem Solved: Addressing the costly delays, defaults, and lost-work losses incurred by high-upload productivity tools like daily commuter and commercial transport vehicles due to fuel system failures.

  Value Brought: Our warehousing center maintains ample stock of best-selling specifications year-round. Orders are responded to quickly, with priority packing and dispatch within 24-48 hours, significantly shortening logistics and delivery cycles. This helps fleets and owners quickly restore equipment availability and effectively avoids downtime losses.

• Advantages: Specially hardened alloy needle valves and corrosion-resistant hardened coating.

  Problem Solved: Addressing the issue of premature wear and valve core seizure caused by differences in diesel lubricity and sulfur content in different regions.

  Value Brought: Core valve components are made of high-strength special bearing steel with a surface corrosion-resistant hardening treatment, significantly improving fatigue resistance and wear resistance. Even under harsh environments and prolonged high-load operation, it maintains stable performance, avoiding the additional costs of frequent disassembly and repairs.

High-Frequency Urban Commuting and Daily Driving Conditions of Compact Diesel Vehicles: Small diesel cars and SUVs frequently start and stop in stop-and-go urban traffic, placing extremely high demands on fuel supply response speed and idle smoothness. When owners notice severe idling vibration, sluggish acceleration response, or excessive emissions, 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 express delivery scenarios: Business MPVs and small vans conduct intensive cargo deliveries between cities, with vehicles operating at full load for extended periods. When vehicles experience difficulties climbing hills in high gears, abnormally increased fuel consumption, or engine misfires, the repair team replaces the fuel injection valves with a complete set of high-specification ones. Precise atomization and flow control allow the engine to unleash abundant power again, significantly improving fuel efficiency per 100 kilometers and ensuring timely delivery.
