<Product Description> This high-pressure electronically controlled common rail injection assembly (standard part number: 0445120094, common OEM corresponding part numbers include 51101006070, 51101006078, etc.) is meticulously crafted for heavy-duty trucks and commercial diesel power systems (such as MAN D2066 and D2676 series engines). It is the core control component for achieving ultra-high pressure precision metering and micron-level atomization of diesel fuel. The product is widely used in long-haul logistics tractors, long-distance passenger buses, mining dump trucks, and high-load diesel generator sets.
This product adheres to the design philosophy of "multi-pore ultra-micro atomization and millisecond-level precise response." The internal needle valve assembly and armature valve core are both subjected to high-precision grinding and low-friction polishing, and the surface is covered with a dense, anti-coking hardened coating, which effectively resists early erosion caused by impurities in inferior diesel fuel. After the equipment is upgraded, drivers and operators will experience noticeable performance improvements: ignition and starting are crisp and smooth, and the severe vibrations at low idle speeds are completely eliminated; during heavy-load climbing of steep slopes or high-intensity continuous operation, throttle response is tight and smooth, power is continuous and abundant, and black smoke emissions are significantly reduced, resulting in excellent overall fuel economy control.

<Product Advantages>
Advantages: Direct manufacturing in a self-operated automated factory.
Problems Solved: Addresses the problems of complex traditional OEM procurement processes, which can lead to dimensional discrepancies in parts, uneven fuel supply to cylinders, and high-pressure leakage risks, while also significantly increasing procurement costs.
Value Gained: Utilizing a standardized self-built production base for end-to-end precision manufacturing eliminates layers of intermediaries, ensuring consistent injection height across cylinders. This reduces maintenance costs and provides a robust and reliable power guarantee for long-term equipment operation.
Advantages: 100% fully simulated digital bench rigorous quality inspection.
Problems Solved: Addressing quality issues such as delayed solenoid valve response, internal pressure leakage, and needle valve jamming common with low-quality parts, leading to unstable power after installation and wasted time and money on repeated disassembly and debugging.
Value Brought: Each injector undergoes fully automated testing before leaving the factory. Under simulated high temperature and ultra-high pressure conditions, the injection volume and return oil sealing are precisely calibrated for different pressure ranges, ensuring immediate usability after installation and significantly saving time and costs associated with equipment disassembly and debugging.
Advantages: A large, readily available inventory and rapid warehousing and distribution.
Problems Solved: Addressing the costly delays and lost work time caused by fuel system failures affecting commercial vehicles and construction machinery, resulting in downtime and material shortages.
Value Brought: The warehousing center maintains a sufficient stock of best-selling specifications year-round. Orders are responded to quickly, with priority 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 downtime losses.
Advantages: Made of special hardened alloy wear-resistant and corrosion-resistant material.
Problem Solved: Addressing the issue of premature wear and valve core seizure caused by variations in diesel lubricity and sulfur content across different regions.
Benefits: The core valve assembly utilizes high-strength special bearing steel and undergoes a surface anti-corrosion hardening treatment, significantly improving fatigue resistance and wear resistance. It maintains stable performance even under harsh environments and prolonged high-load operation, avoiding the additional costs associated with frequent disassembly and repairs.

<Application Scenarios> Long-distance heavy-duty logistics transportation and mountain steep slope climbing scenarios: Large semi-trailer tractors operate for extended periods on inter-provincial trunk lines, requiring the engine to continuously withstand high load pressure. When drivers notice the vehicle's inability to climb hills, abnormally high fuel consumption, or black smoke, they replace the original aging parts and install this high-precision fuel injector. After installation, the engine's fuel atomization effect is significantly improved, throttle response is more robust, effectively reducing overall fuel consumption and ensuring high efficiency and stability in long-distance transportation.
Urban construction projects and high-intensity construction scenarios for special-purpose machinery: Engineering dump trucks, large excavators, and other equipment operate continuously for extended periods in high-dust, high-load environments. When the equipment exhibits severe idling vibration, difficulty starting, or excessive emissions, on-site maintenance personnel promptly replace the entire set of high-quality injectors. Precise injection control ensures stable power output even under extreme operating conditions, preventing stalling or abnormal wear caused by uneven fuel supply.
Application Scenarios
Q: Can I use the product directly after installation? Is a correction code required?
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.
Q: What is the inventory and delivery time 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 the product before it leaves 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 of superior quality from the outset.
Q: How long is the warranty period? What are the after-sales service details?
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.
