Product Description
This specification of electronically controlled high-pressure common rail fuel injection valve body assembly (standard part identification code: 33800-4X450 / 338004X450, common cross-reference and OE interchangeable parts include 28231014, 28264952, EJBR05501D, EJBR03001D, etc., mainly matched with the J3 series 2.9L CRDi four-cylinder diesel power platform, widely installed in light pickup trucks, commercial MPVs, off-road SUVs, and multi-purpose passenger and freight vehicles) is meticulously manufactured. 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 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 consumption control and smooth driving experience.
Product Advantages
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 suchs 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.

Application Scenarios
High-frequency urban commuting and daily driving conditions for multi-purpose pickup trucks: Diesel pickup trucks 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 promptly replace the fuel injectors with this high-precision common rail injector. After 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 business MPV operation scenarios: Business MPVs and light vans are used for passenger and freight transport between cities, with vehicles operating under high-load cruising conditions for extended periods. When vehicles experience issues such as weak climbing in high gears, abnormally increased fuel consumption, or engine misfires, our maintenance team replaces the entire set of high-specification fuel injectors. Precise atomization and flow control allow the engine to regain its full power, significantly improving fuel efficiency per 100 kilometers and ensuring timely transportation.
Frequently Asked Questions
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 (C2I / C3I / 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 is the inventory and delivery time for bulk purchases?
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.
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 when using our products.
