<Product Description> This high-pressure electronically controlled common rail nozzle valve body assembly (standard part identification code: 2419679; common cross-reference and OE interchangeable identification numbers include 241-9679, 0445120349, 0445 120 349, etc., mainly compatible with DC09, DC13, and DC16 series large-displacement high-pressure common rail diesel engines, widely installed in heavy-duty long-haul highway tractors, engineering dump trucks, and large generator sets) is precision-manufactured. As a micro-metering and ultra-fine spray execution unit in the fuel supply system with extremely high control precision requirements, 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 response, promoting comprehensive and uniform mixing of fuel and air and achieving efficient combustion.
The product adheres to the precision manufacturing standards of "micron-level high-pressure atomization and millisecond-level ultra-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 covered 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, mechanics and fleet drivers will experience a clear and intuitive performance improvement: cold start in the morning is crisp and rapid, and the severe vibration and shaking at low-speed idling have completely disappeared; during heavy-load starts, fully loaded uphill climbs, or highway overtaking, the accelerator pedal response is firm and sensitive, acceleration is smooth and powerful, and exhaust smoke is significantly improved, resulting in a satisfying driving experience and excellent fuel efficiency.

<Product Advantages>
Problems Solved: Addresses issues such as accumulated tolerance issues in parts, uneven fuel supply to cylinders, and high-pressure leakage risks inherent in traditional OEM and multi-level distribution chains, while effectively reducing intermediate procurement costs.
Value Brought: Utilizing a self-operated standardized production base for precise control, eliminating intermediate markups, and ensuring highly consistent fuel injection volume across all cylinders, providing robust and reliable power support for vehicle and equipment operation while reducing maintenance budgets.
Problems Solved: Addresses issues such as response delays, pressure relief jamming leading to engine misfires and vibrations, and wasted time and money due to repeated disassembly and adjustment, which are common with low-end parts.
Value Brought: Each injector undergoes fully automated digital testing before leaving the factory, precisely calibrating fuel injection volume and sealing performance across different pressure ranges under simulated high-temperature and ultra-high-pressure conditions, ensuring immediate usability upon installation and significantly saving time and costs associated with equipment disassembly and adjustment.
Problem Solved: Addressing the costly delays and lost work due to fuel system malfunctions causing commercial freight and daily passenger vehicles to become high-utilization productivity tools.
Value Brought: Our warehousing center maintains ample stock of best-selling specifications year-round. Orders are processed quickly, with packaging 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.
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 utilize high-strength special bearing steel and a surface anti-corrosion hardening treatment, significantly improving fatigue resistance and wear resistance. This ensures stable performance even under harsh environments and prolonged high-load operation, avoiding the additional costs of frequent disassembly and repairs.

<Application Scenarios> Long-haul logistics and heavy-duty tractor-trailer inter-provincial transportation: Heavy-duty trucks and semi-trailer tractors continuously travel fully loaded on inter-provincial highways and trunk logistics routes, placing extremely high demands on engine fuel supply stability and fuel economy. When truck drivers notice sluggish acceleration for overtaking, insufficient power when climbing hills in high gears, or black smoke from the exhaust pipe, mechanics promptly replace the fuel with this high-precision common rail injection valve. After replacement, fuel atomization is extremely fine and uniform, engine power reserves are fully restored, throttle response is brisk, and overall fuel consumption per 100 kilometers is effectively reduced.
Urban construction waste transportation and heavy transport scenarios: Construction waste trucks and concrete mixer trucks frequently start and climb hills in complex road conditions and dusty construction sites. When vehicles experience starting difficulties, severe idling vibrations, or uneven cylinder operation, the maintenance team replaces the entire set of high-specification fuel injection components. Precise electronic injection control allows the engine to instantly release high torque at low speeds, smoothly handling frequent start-stop cycles and heavy loads, ensuring efficient and smooth transportation operations.
</Application Scenarios>
**Application Scenarios**
A: Each injector has a unique flow correction code (IMA 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.
A: We have our own factory and large warehouse, and maintain a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can also be quickly scheduled for production line setup.
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.
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 when using our products.
