Common Rail Injector 22717956 Bebe5g17001 Bebe5g17101 Bebe5g09001 Bebe5g17001 Fuel Injector for Vo-lvo MD16 P3622 Diesel Engine

This electronically controlled, unit-type diesel injection valve assembly (Part ID: 22717956; common OE cross-references include 22717956-P, 85023247, 24111932, 22459521, 7422717956, etc.) is precision-engineered. It is designed primarily for the D13K/D13K460/D13K500 series—a 12.8L, heavy-duty, inline-six diesel engine platform compliant with China VI and Euro VI emission standards. It is widely installed in next-generation heavy-duty trucks (FH4, FH5, FM4, FM5, FMX series) used for highway logistics, specialized heavy-load towing, large-scale construction dump trucks, and high-power industrial backup generator sets. As a core actuator within the heavy-duty commercial vehicle's ultra-high-pressure fuel system, it facilitates precision micro-atomization and ultra-short pulse metering. Working in synergy with the overhead camshaft's mechanical stroke and the electronic control system's high-speed electromagnetic actuation (operating at the microsecond level), it rapidly injects diesel at ultra-high pressure, dispersing it into fine droplets to ensure thorough mixing and combustion with the compressed intake air inside the cylinder.

The component is manufactured to rigorous standards emphasizing microscopic fit precision, mechanical fatigue resistance, and high-pressure impact resilience. Its internal precision plunger assembly and nozzle components are crafted from select aerospace-grade, quenched special alloy bearing steel. These parts undergo ultra-high-precision micron-level geometric grinding and low-friction mirror polishing, and feature a dense, ultra-hard, wear-resistant, and anti-corrosive surface coating. This design effectively prevents mechanical scratching and high-pressure internal leakage caused by microscopic impurities found in low-quality diesel fuel.

Quality-controlled direct supply from the source factory. We eliminate issues common to multi-layered distribution—such as excessive mechanical tolerances, inconsistent cylinder fuel delivery, and high-pressure seal leaks—while effectively reducing procurement costs. Leveraging our own production base equipped with modern CNC machinery, we control the entire machining and assembly process. By cutting out intermediary markups and ensuring highly balanced fuel injection pressure and flow across cylinders, we provide reliable power for vehicles and heavy equipment while simultaneously lowering maintenance budgets.

Strict calibration on ultra-high-pressure digital dynamic test benches. Inferior replacement injectors often suffer from sluggish response, internal pressure loss, or sticking—causing severe engine vibration and misfires—as well as wasted labor costs from repeated installation and adjustment. Every fuel injector assembly is tested on a fully automated digital rig after assembly in a clean-room environment. We calibrate pre-injection volume, full-load flow, and return-line sealing under simulated ultra-high-pressure and extreme-temperature conditions. This ensures "ready-to-install" performance, drastically saving time and costs associated with installation and tuning.

Large-scale inventory and rapid shipping. Heavy-duty trucks in long-haul logistics are high-turnover assets; fuel system failures that sideline vehicles result in costly downtime losses. Our warehouse maintains substantial stock levels year-round. Orders are packed and shipped within 24–48 hours of confirmation, significantly shortening wait times. This helps fleets and end-users quickly resume operations and avoid losses caused by vehicle downtime. Features a specially quenched alloy needle valve and a wear-resistant, hardened coating. It addresses issues found in certain operating environments—such as poor diesel lubricity and sulfur impurities—that often lead to premature wear, scoring, and seizure of mating components (specifically the plunger assembly). The core components utilize high-hardness, specialty bearing steel and undergo surface anti-corrosion treatment, resulting in significantly enhanced fatigue and wear resistance. This ensures stable performance even under harsh conditions and prolonged, high-load operation, thereby reducing the additional costs associated with frequent disassembly and repair.

Long-haul, cross-provincial, heavy-load logistics operations: Container semi-trucks powered by D13K Euro VI diesel engines operating at full capacity on trunk highways, covering long distances across both flat expressways and continuously undulating mountainous terrain. When a vehicle exhibits sluggish acceleration, delayed power response, or abnormally high fuel consumption while climbing under heavy load, the maintenance team replaces the existing units with a full set of high-precision electronically controlled fuel injectors. Following installation, fuel atomization is rapid and thorough, and heavy-load acceleration becomes robust and smooth, ensuring timely and efficient delivery of freight.

Large-scale open-pit mining and heavy-duty engineering material transport: Heavy-duty dump trucks operate continuously under high loads between quarries and earthwork sites, enduring harsh conditions such as heavy dust, intense vibration, and sustained heavy-duty stress. When the powertrain experiences slow cold starts, severe idle vibration, or stalling under load, maintenance personnel promptly install this high-specification fuel injector assembly; the consistent, ultra-high-pressure injection enables the engine to deliver powerful, stable torque, ensuring continuous, high-efficiency operation for heavy engineering vehicles.

Q: Can the product be used immediately after installation? What precautions should be taken during installation?
A: Each fuel injector undergoes precise parameter calibration during factory testing. Before installation, thoroughly clean the cylinder head mounting bore and fuel lines to remove all impurities; replace the high-temperature-resistant rubber seal and the specialized copper washer with new ones; use a torque wrench to tighten fasteners in strict accordance with OEM maintenance specifications; and bleed air from the fuel system before starting the engine to ensure proper operation.

Q: What are the stock levels and shipping lead times for bulk orders?
A: We operate our own factory and a large, specialized warehouse, maintaining substantial safety stock of this model year-round. Standard orders can be packed and shipped within 24–48 hours, while bulk orders benefit from flexible production scheduling, ensuring a highly efficient and stable supply chain.

Q: How are product quality and performance guaranteed before leaving the factory?
A: All fuel injectors are assembled in an ultra-clean workshop and undergo 100% automated bench testing across all operating conditions. These rigorous tests cover critical parameters such as sealing integrity, pressure build-up during cold starts, injection volume consistency across various loads, and fuel return leakage, ensuring that every unit is of premium quality upon delivery.
Q: What is the warranty period for the product, and how is after-sales service handled?
A: We offer a 12-month warranty. Should any performance failure occur during the warranty period due to factors other than human error or contamination from fuel impurities, we provide rapid replacement or technical support to ensure a worry-free experience.
