Common Rai Diese Fuel Injector 0445110192 A6470700087 for Mercedes 2.2 CD0m646

This high-pressure electronically controlled common-rail fuel injector assembly (Part ID: 0445110192 / 0 445 110 192; common cross-references and OE interchange numbers include 6110701687, A6110701687, 0986435088, etc.) is precision-engineered. Designed primarily for 2.2 CDI and 2.7 CDI inline diesel engine platforms—and widely used in vehicles such as Sprinter light commercial vans, C-Class and E-Class diesel sedans, and SUVs—it serves as the core micro-actuator within the fuel supply system. It is responsible for rapidly atomizing high-pressure diesel into ultra-fine, micron-sized droplets in response to millisecond-level electrical signals, thereby facilitating efficient mixing and combustion with the intake air.

The component embodies precision standards emphasizing rapid electronic response and ultra-fine atomization. Its internal needle valve assembly and control valve spool are crafted from aerospace-grade, hardened special alloy steel, featuring ultra-high-precision geometric grinding and low-friction polishing. The surfaces are treated with a dense, highly wear-resistant coating to effectively prevent premature abrasion or sticking caused by fuel impurities. Upon installation, drivers and technicians will notice immediate, tangible improvements: cold starts are crisp and swift, and vibrations during low-speed idling are significantly reduced. Whether navigating stop-and-go city traffic, climbing steep hills, or cruising at highway speeds, the throttle response is precise and immediate, delivering smooth acceleration and sustained power. Additionally, exhaust smoke emissions are noticeably reduced, resulting in optimized fuel efficiency and a smooth, responsive driving experience.

• Direct manufacturing by the factory and comprehensive quality control throughout the entire production process. Effectively reduces procurement costs while addressing issues such as tolerance accumulation across multi-tier distribution chains, uneven fuel delivery across cylinders, and risks of high-pressure leakage. Leveraging standardized production bases for end-to-end precision control and eliminating intermediary markups, the process ensures highly consistent fuel injection across cylinders; this cuts maintenance budgets while providing reliable, robust power for vehicle operation.
• Rigorous testing on dynamic test benches covering all operating conditions. Addresses common issues with inferior replacement parts—such as response lag, pressure-relief valve sticking (causing engine misfires and vibration), and wasted labor/costs from repeated installation and adjustment. Every component undergoes automated testing before leaving the factory, with precise calibration of fuel injection volumes and sealing integrity across various pressure ranges under simulated real-world conditions (high temperature and ultra-high pressure). This ensures "ready-to-install" capability, drastically saving time and costs associated with equipment installation and tuning.
• Large-scale, consistent warehousing and rapid shipping response. Addresses the high operational demands of daily commuter and commercial transport vehicles, where fuel system failures lead to costly downtime and delays. Warehousing centers maintain ample stock of popular specifications year-round; orders are prioritized for packing and dispatch within 24–48 hours of confirmation. This significantly shortens logistics cycles, helping fleets and owners quickly restore vehicle availability and effectively avoiding losses caused by downtime.
• Specialized quenched alloy needle valves with wear-resistant protective coatings. Addresses premature wear and valve sticking in mating components caused by regional variations in diesel lubricity and sulfur content. Core valve components utilize high-strength specialized bearing steel and surface hardening/anti-corrosion treatments, vastly enhancing fatigue and wear resistance. Stable performance is maintained even under harsh environments and prolonged high-load operation, preventing the extra expenses associated with frequent disassembly and repair.

Ideal for high-frequency urban commuting and premium diesel passenger vehicle operation: Diesel passenger cars and SUVs frequently encounter stop-and-go traffic, demanding rapid fuel delivery response and stable idling. This high-precision common rail injector is the recommended replacement when vehicle owners notice significant idle vibration, sluggish acceleration response, or excessive exhaust smoke. After installation, the fuel injection response is sharp and immediate; the engine returns to a quiet, smooth idle, and power is delivered steadily the moment the throttle is lightly pressed.

Light-duty passenger/cargo transport and intercity business/logistics delivery scenarios: Business MPVs and small logistics vans frequently operate on intercity routes, often cruising under high loads for extended periods. When vehicles experience sluggishness on hills in high gears, abnormal fuel consumption, or engine misfires, the maintenance team installs a full set of high-specification fuel injectors. Precise control over atomization and flow restores the engine's robust power output, significantly improves fuel efficiency, and ensures timely deliveries.

Q: Can the product be used immediately after installation, or does a correction code need to be entered?

A: Each fuel injector is assigned a unique flow correction code (IMA/QR code) during factory testing. We recommend using a diagnostic tool to program this code into the engine control unit (ECU) after installation to achieve optimal fuel efficiency and smooth operation.

Q: What are the stock levels and lead times for bulk orders?

A: We operate our own factory and large-scale warehouses, maintaining substantial, year-round stock of this model. Standard orders are packed and shipped within 24–48 hours, while bulk orders can be quickly scheduled for production.

Q: How are product quality and performance ensured before leaving the factory?

A: All fuel injectors undergo assembly in a Class 100 cleanroom environment and 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pre-injection volume, full-load injection volume, and fuel return volume; our rigorous standards ensure that every unit is a high-quality product.

Q: What is the warranty period, and how is after-sales support handled?

A: We offer a 12-month warranty. In the event of a performance failure due to non-human factors within the warranty period, we provide rapid replacement or technical support to ensure a worry-free experience.
