Common Rail Injector 85003264 Bebe4d08002 Bebe4d16002 Bebe4d24002 Fuel Injector Assy for Vo-lvo MD13 High Power Engine

<Product Description>
This electronically controlled diesel fuel injection valve assembly (Part ID: 85003264; common OE cross-references include 85003264-P, 20525203, 20584346, 21340611, 0414703009, etc.) is precision-engineered for the D16/D16C/D16E/D16G series—a 16.1L, high-displacement, six-cylinder heavy-duty diesel engine platform. It is widely utilized in FH16 (540/600/700 hp) ultra-heavy-duty tractors, large port container reach stackers, specialized heavy-haulage prime movers, heavy mining excavation equipment, and high-power backup diesel generator sets. As a core actuator within the high-pressure fuel supply system of these high-horsepower engines, it enables ultra-fine atomization and microsecond-level multi-stage injection metering. Driven by a robust overhead camshaft and high-speed electromagnetic control, it rapidly pressurizes fuel and uniformly disperses it into micron-sized particles, ensuring thorough mixing and combustion with the massive intake air volume within the cylinders.

The component is designed and manufactured to meet rigorous standards for microscopic fit precision, extreme mechanical fatigue resistance, and resilience against ultra-high-impact forces. Its internal pressurizing plunger assembly and nozzle components are crafted from select aerospace-grade, hardened special alloy steel, featuring ultra-precise geometric grinding and mirror-like polishing. The surfaces are coated with a dense, ultra-hard, wear-resistant, and anti-corrosive layer, effectively preventing mechanical scoring and high-pressure leakage caused by microscopic fuel impurities. Once the components are installed, both mechanics and drivers can immediately perceive a significant upgrade in the vehicle's performance: cold starts are crisp and rapid, while the large-displacement engine idles smoothly with a deep, balanced mechanical tone. Whether starting under heavy loads, climbing steep gradients, or cruising at full load, the throttle response is sharp and robust, and power delivery is seamless. Additionally, black exhaust smoke is reduced, delivering the high uptime and fuel efficiency that fleet operators demand.

<Product Advantages>
Quality control through standardized, smart manufacturing and direct supply from the source factory. We effectively lower procurement costs by eliminating the excessive tolerances, fuel delivery inconsistencies across cylinders, and high-pressure sealing risks often caused by multiple intermediaries in the supply chain. Leveraging modern precision machine tools at our own production base, we control the entire machining and assembly process; by cutting out unnecessary markups, we ensure highly consistent injection pressure and fuel volume across all cylinders. This reduces maintenance budgets while providing reliable, solid power for high-horsepower heavy-duty trucks and heavy equipment.

Rigorous testing on ultra-high-pressure digital dynamic test benches across all operating conditions. Inferior replacement injectors often suffer from sluggish valve opening or pressure-release sticking—leading to severe engine vibration and misfires—as well as wasted labor costs from repeated installation and adjustment. After assembly in a clean-room environment, every injector assembly undergoes calibration on a fully automated digital test bench. We calibrate pre-injection volume, full-load flow, and return-line sealing under simulated ultra-high-pressure and extreme high-temperature conditions. This ensures the units are ready for immediate installation, drastically saving time and costs associated with equipment disassembly and tuning.

Large-scale warehousing with consistent stock availability and rapid shipping. We address the critical needs of heavy-duty logistics tractors and specialized heavy machinery—high-value production assets where fuel system failures can lead to costly downtime and operational losses. Our warehouse maintains ample stock year-round; upon order confirmation, items are promptly packed and shipped within 24–48 hours. This significantly reduces logistics lead times, helping fleets and end-users rapidly restore operational capacity and avoid losses associated with downtime.

We utilize specially quenched alloy needle valves featuring wear-resistant, hardened coatings. These components are engineered to address challenges in demanding operating conditions—such as poor diesel lubricity and sulfur impurities—that often cause premature wear, scoring, or seizure of the plunger assembly. By employing high-hardness, specialized bearing steel and advanced surface anti-corrosion treatments, the components offer superior fatigue and wear resistance. They maintain stable performance even under harsh environments and prolonged, high-load operation, thereby reducing the additional costs associated with frequent disassembly and repair. </Product Advantages>

<Application Scenarios>
Oversized cargo transport and heavy-load long-haul logistics: Utilized in multi-axle, ultra-heavy semi-trailers powered by 16L high-horsepower diesel engines for transporting loads exceeding 100 tons—such as wind power equipment and large steel structures—navigating frequent long-distance, high-load uphill climbs and harsh road conditions. When vehicles experience sluggish power delivery, unresponsive acceleration, or abnormally high fuel consumption during steep-grade starts, the maintenance team replaces the existing units with a full set of high-precision electronically controlled fuel injectors. Post-installation, the system delivers rapid, uniform ultra-high-pressure atomization and robust acceleration under heavy loads, ensuring the safe and punctual delivery of critical logistics shipments.

Open-pit mega-mine heavy machinery operations: Large crawler excavators and heavy-duty ore dump trucks operate under continuous high-load conditions, enduring harsh environments characterized by heavy dust, rough terrain, and relentless full-load stress. When powertrains exhibit sluggish cold starts, noticeable idle instability, or stalling under heavy loads, maintenance personnel promptly install these high-spec fuel injector assemblies. The consistent, ultra-fine injection ensures the engine delivers steady, powerful torque, maintaining the continuous, high-efficiency uptime of mining equipment.

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

Q: What are the stock levels and shipping lead times for bulk orders?
A: We operate our own factories and large-scale professional warehouses, maintaining substantial safety stock of this core model designed for high-displacement engines. Standard orders are packed and shipped within 24–48 hours of confirmation; for large-scale fleet orders, we can rapidly adjust production schedules to ensure a stable and efficient supply chain.

Q: How are product quality and performance ensured 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 tests cover critical parameters such as sealing integrity, pressure build-up during cold starts, injection quantity 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 professional technical support to ensure you have complete peace of mind.
