Fuel Injector 3801551 Bebe4d35001 Bebe4d04001 Common Rail Injector for Vo-lvo MD11 Euro3

This model of diesel engine high-pressure fuel pump/fuel transfer pump assembly (standard part code: 3801551, common cross-reference and OE interchangeable parts include 3801551PX, 3801551RX, 3015971, 3054234, etc., mainly matched with 14.0L large-displacement heavy-duty diesel power platforms such as N14 and NT855, commonly used in heavy-duty long-haul trucks, highway tractors, large engineering generator sets, and mining equipment) is precision-manufactured. As the power core and high-pressure establishment unit of the entire fuel supply system, it bears the heavy responsibility of continuously establishing and maintaining low-pressure diesel fuel at ultra-high steady-state pressure, accurately delivering it to the fuel rail and injection actuator, ensuring that the fuel supply pressure and flow perfectly match the engine's combustion requirements under different loads.

The product adheres to industrial manufacturing standards of "steady-state high-pressure output, wear-resistant, corrosion-resistant, and durable." The pump body utilizes a high-density forged alloy structure, and the internal plunger assembly and control valve components undergo high-precision geometric grinding and low-friction surface hardening coating, providing excellent fatigue resistance and resistance to diesel fuel contamination. After installation, equipment operators and fleet maintenance personnel experience significant performance improvements: crisp and rapid start-up; quick and stable oil pressure build-up at low idle speeds; and abundant and sustained power output during heavy-load climbing or continuous operation of full-power generators, without idling fluctuations or high-load stalling, effectively ensuring fuel supply efficiency and high equipment uptime.

Long-Distance Heavy-Duty Transportation and Highway Tractor-Trailer Operations: Heavy-duty trucks and logistics tractors often operate at full load during inter-provincial trunk line transportation, placing extremely high demands on the continuous fuel supply capacity of the high-pressure oil pump. When truck drivers notice insufficient acceleration or insufficient oil pressure causing engine power reduction during uphill driving, the maintenance team promptly replaces this high-pressure oil pump. After replacement, the oil pressure builds up quickly and stably, providing ample and smooth acceleration under heavy loads, ensuring timely and efficient long-distance transportation.

Large-Scale Engineering Generator Sets and Continuous Power Supply Scenarios in the Field: Generator sets and engineering transport vehicles operate continuously and uninterruptedly at full load in field mining areas or construction sites. When equipment exhibits abnormalities such as start-up delays or severe fluctuations in speed and oil pressure under increased load, on-site technicians promptly replace the high-pressure oil pump. A stable fuel pressure supply ensures the engine maintains a constant speed during full-power operation, guaranteeing continuous and stable power output for engineering and operations.
