This high-pressure electronically controlled common rail injector assembly (part number: 0445120383, common interchangeable/OE part numbers include 0445120150, 612600080618, 612600080977, etc.) is precision-engineered for heavy-duty diesel engines (such as Weichai WP10, WP12, and Blue Engine series engines), and is widely applicable to heavy-duty long-haul logistics trucks, engineering dump trucks, large generator sets, and mining machinery. The product integrates ultra-high pressure fine atomization and microsecond-level electromagnetic response control, making it a core actuator for achieving precise metering and efficient combustion in the fuel supply system.
After the replacement equipment is installed, drivers and equipment operators will experience a direct improvement in power and quality: ignition is crisp and smooth, and the severe vibrations and intermittent noises at low idle speeds are completely eliminated; power output is continuous and abundant when the accelerator is pressed, and torque remains smooth and undiminished during heavy-load climbing or continuous heavy-load operation. Simultaneously, black smoke from the exhaust is significantly reduced, resulting in excellent overall fuel economy and driving experience.
Advantages: Standardized precision manufacturing in a directly operated factory.
Problems Solved: Traditional outsourcing often leads to dimensional deviations in component fit and inconsistent batch performance, resulting in uneven fuel supply to cylinders and potential high-pressure leaks.
Value Brought: Relying on a standardized self-built production base for end-to-end precision manufacturing, from micron-level machining of needle valve components to automated assembly, the entire process is controlled to ensure consistent injection height in each cylinder, providing a solid and reliable power guarantee for long-term equipment operation.
Advantages: 100% rigorous quality inspection under all operating conditions on a fully digital test bench.
Problem Solved: Inferior parts can easily lead to unstable vehicle performance, cylinder scoring, knocking, and wasted time and money due to repeated disassembly and adjustment.
Value Brought: Each injector undergoes a fully automated digital testing bench before leaving the factory. Under simulated high-temperature and ultra-high-pressure working conditions, the injection volume and return oil sealing performance across different pressure ranges are precisely calibrated, ensuring immediate usability upon installation and significantly saving time and costs associated with equipment maintenance and debugging.
Advantages: A large, readily available inventory and efficient warehousing and distribution.
Problem Solved: Construction machinery and commercial trucks are high-uptime, high-revenue tools. A breakdown due to fuel system failure can result in costly delays, compensation for lost work time, and other losses.
Value Brought: The warehousing center maintains a large inventory of best-selling specifications year-round. Orders are responded to quickly, with priority packing and shipping within 24-48 hours, significantly shortening logistics cycles and helping fleets and owners quickly restore equipment availability, effectively mitigating losses from downtime.
Advantages: Specially hardened, wear-resistant, and corrosion-resistant materials.
Problem Solved: Differences in diesel lubricity and sulfur content across different regions can easily lead to premature wear of valve components and valve core seizure.
Value Gained: The core valve components are made of high-strength special bearing steel and undergo surface anti-corrosion hardening treatment, significantly improving fatigue resistance and wear resistance. Even under harsh environments and prolonged high-load operation, they maintain stable performance, effectively avoiding the additional costs associated with frequent disassembly and repairs.

Heavy-Duty Logistics and Inter-Provincial Trunk Freight Transportation: Large semi-trailer tractors operate for extended periods on inter-provincial trunk lines, requiring their engines 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.
Mining and High-Intensity Construction Scenarios for Large Engineering Machinery: Large engineering dump trucks and excavators operate continuously in high-dust, high-load environments, placing extremely high demands on the stability of the fuel supply system. 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 output even under extreme operating conditions, preventing engine stalling or abnormal wear caused by uneven fuel supply.
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.
