A6510702887 28348370 Fuel Injector for Mercedes Benz W906 W204 W212 W207

This model of electronically controlled piezoelectric/sonic valve type high-pressure common rail injector assembly (standard OE part number: A6510702887 / A 651 070 28 87, common cross-reference and interchangeable parts include 6510702887, 28231014, 28236381, 28231013, EMBR00002D, etc., mainly matched with OM651 series 1.8 CDI / 2.1 CDI / 2.2 CDI inline four-cylinder diesel power platform, widely installed in C-class, E-class, GLK, S-class, V-class/Vito, Sprinter light commercial truck and multi-purpose SUV, etc.) is meticulously crafted. As a core actuator in the fuel supply system that controls the atomization quality and pulse injection timing of high-pressure diesel fuel, it bears the crucial responsibility of precisely metering and rapidly dispersing high-pressure diesel fuel into micron-sized ultrafine droplets under microsecond-level electrical signal commands, promoting thorough mixing and combustion between fuel and intake airflow.

The product is designed with the precision standards of "ultra-fast response and micro-ultrafine atomization." Internal needle valve components and control valve cores are made from 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 plating layer, effectively preventing early erosion and jamming caused by diesel impurities. After the replacement parts are installed, drivers and maintenance personnel will experience a very clear and intuitive improvement: cold starts in the morning are crisp and quick, and the vibration at low idling speeds is smoothed out; in urban driving, steep inclines, or long-distance highway cruising, the accelerator pedal response is firm and responsive, acceleration is smooth and powerful, and exhaust smoke is significantly improved, resulting in satisfactory fuel efficiency and smooth handling.

• Direct manufacturing in a physical factory with full-process quality control. Effectively reduces procurement costs by addressing issues such as accumulated tolerances exceeding standards, uneven fuel supply to cylinders, and high-pressure leaks caused by multi-level distribution chains. Utilizing a standardized production base for precise full-process control, eliminating intermediate markups, and ensuring highly consistent fuel injection in each cylinder, this reduces maintenance budgets while providing a solid and reliable power guarantee for vehicle operation.
• Rigorous testing on a full-condition dynamic test bench. Addressing the issues of delayed response, engine misfires and vibrations caused by pressure relief jamming, and wasted time and money due to repeated disassembly and reassembly adjustments that are common with inferior replacement parts, each component undergoes automated testing before leaving the factory. Under simulated high-temperature and ultra-high-pressure conditions, the fuel injection volume and sealing performance are precisely calibrated for 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 shipping response. For daily commuting and commercial transport vehicles, which are high-upload productivity tools, the costly downtime and delays caused by fuel system failures can be significant. Our warehousing center maintains ample stock of best-selling specifications year-round. After order confirmation, we respond quickly and prioritize packing and shipping within 24-48 hours, greatly shortening the logistics and delivery cycle and helping fleets and owners quickly restore equipment availability, effectively avoiding downtime losses.
• Special hardened alloy needle valves and wear-resistant coating protection. Addressing the issue of premature wear and valve core jamming caused by differences in diesel lubricity and sulfur content in different regions. The core valve assembly is made of high-strength special bearing steel and undergoes a surface anti-corrosion hardening treatment, significantly improving its 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.

High-frequency urban commuting and high-quality sedan/SUV driving conditions: Diesel passenger cars and SUVs frequently start and stop in stop-and-go urban traffic, requiring extremely high fuel supply response speed and idle smoothness. When the owner notices obvious idle vibration, sluggish acceleration response, or excessive exhaust smoke, maintenance personnel should promptly replace this high-precision common rail injector. After the replacement, the fuel injection response is sensitive and rapid, the engine idles quietly and smoothly, and power is delivered immediately and steadily with a light touch of the accelerator.

Light passenger and freight transport and intercity business/logistics delivery scenarios: Business MPVs and small logistics vans frequently deliver goods between cities, and the vehicles are under high-load cruising conditions for extended periods. When vehicles experience difficulty climbing hills in high gears, abnormally increased fuel consumption, or engine misfires, the repair team replaces the entire set of high-specification fuel injection valves. Precise atomization and flow control allow the engine to unleash abundant power again, significantly improving fuel efficiency per 100 kilometers and ensuring timely delivery.

Q: Can I use it directly after receiving the product? Do I need to enter a correction code?

A: Each injector has a unique flow correction code (C2I / C3M / QR code) generated during factory testing. It is recommended to use a diagnostic tool to flash the correction code into the engine computer (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 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 the products are of superior quality from the outset.

Q: How long is the product warranty period? What about after-sales service?

A: We offer a 12-month warranty period. If a performance failure occurs due to non-human factors within the warranty period, we provide rapid replacement or after-sales technical support to ensure your peace of mind.
