Product Description

This high-pressure electronically controlled common rail injection assembly (standard product code: 0445120384, common OEM corresponding part numbers include 0986435622, 612600080934, 612600080618, etc.) is precision-engineered for large-displacement heavy-duty trucks, buses, and construction machinery diesel engines (such as WP10, WP12 series heavy-duty engines). As the core of the high-pressure common rail fuel system, it is responsible for the precise metering and ultra-fine atomization of ultra-high-pressure diesel fuel with a microsecond-level response speed. It is widely used in long-haul logistics tractors, long-distance passenger buses, heavy-duty engineering dump trucks, and diesel generator sets.

This product adopts the design concept of "high-pressure ultra-fine atomization and high-frequency ultra-fast response." The internal valve needle assembly and solenoid valve core have undergone extremely high-precision geometric grinding and polishing, and the surface is covered with an anti-coking hardening coating, which can effectively resist early erosion caused by diesel impurities. After the equipment is installed and replaced, drivers will experience a very noticeable improvement in handling: cold starts are crisp and rapid, and the severe vibrations and flat-frequency shaking during idling are smoothed out; under full load acceleration or continuous uphill driving, the accelerator pedal feedback is delicate and responsive, with a continuous, abundant, and smooth power output, while significantly reducing exhaust black smoke emissions, resulting in an excellent overall fuel control experience.

Product Advantages
Integrated precision manufacturing in a fully automated factory.

Problems Solved: Traditional multi-level distribution and procurement models are cumbersome, easily leading to excessive tolerances in parts, uneven fuel supply to cylinders, and high-pressure leakage risks, while significantly increasing procurement costs.

Value Brought: Relying on a self-built standardized production base for precision manufacturing throughout the entire process, eliminating layers of intermediaries and ensuring consistent injection height in each cylinder, significantly reducing maintenance costs while providing a solid and reliable power guarantee for long-term equipment operation.

100% rigorous quality inspection on a full-condition digital bench.

Problems Solved: Addressing common issues with inferior, low-end parts, such as atomization angle deviation, sluggish solenoid valve response leading to incomplete combustion, engine misfires, idling vibrations, and wasted time and extra costs associated with secondary disassembly and adjustment.

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 across different pressure ranges, ensuring immediate usability upon installation and significantly reducing time and costs associated with equipment disassembly and adjustment.

Regular, large-scale warehousing and rapid inventory allocation.

Problems Solved: Commercial vehicles and construction machinery are high-upload, high-revenue tools. If they become stranded due to fuel system failures, downtime and lack of materials can result in costly delays, compensation claims, and lost work time.

Value Brought: The warehousing center maintains a sufficient stock of best-selling specifications year-round. After order confirmation, a rapid response and priority packing and dispatch within 24-48 hours significantly shorten logistics and delivery cycles, helping fleets and owners quickly restore equipment operational readiness and effectively avoiding downtime losses.

Special bearing steel and nano-level DLC wear-resistant coating.

Problems Solved: Addresses issues such as premature wear of valve components, needle valve jamming, and excessive oil return caused by variations in diesel lubrication and particulate impurities in different regions.

Value Brought: The 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 associated with frequent disassembly and repairs.

Application Scenarios

Cross-Regional Heavy-Duty Transportation and Mountainous Steep Slope Cruise Conditions: Heavy-duty semi-trailer trucks fully loaded with cargo travel for extended periods on inter-provincial highways, requiring the engine to continuously output high torque. When drivers notice a decrease in vehicle start-up smoothness, weak acceleration uphill, or abnormally increased fuel consumption, replacing the original aging parts and installing this high-precision fuel injector is recommended. After installation, the high-pressure diesel atomization effect is significantly improved, throttle response is more robust, effectively reducing overall fuel consumption and ensuring high efficiency and stability during long-distance transportation.

Continuous operation scenarios in open-pit mines and large construction machinery: Large construction 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 equipment experiences severe idling vibration, difficulty starting, or excessive emissions, on-site maintenance personnel promptly replace the entire set of high-quality fuel injectors. Precise injection control ensures stable output even under extreme conditions, preventing engine stalling or abnormal wear caused by uneven fuel supply.

Frequently Asked Questions
Q: Can I use the product directly after installation? Is it necessary to enter a correction code?
A: Each fuel 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, 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.
