Fuel Injection Pump 094000-0323 6217-71-1122 for Komatsu Engine SA6d 140e Loader Wa50o-3

This model of diesel engine high-pressure electronically controlled common rail fuel pump assembly (standard part identification codes: 094000-0383 / 0940000383 / 094000-0323; common cross-reference and OE interchangeable identification numbers include 22100-E0020, 22100-E0021, 22100E0020, etc., mainly compatible with J08E, J05E and other 5.1L / 7.7L series high-pressure common rail diesel power platforms, widely installed in medium and heavy-duty trucks, engineering vehicles and tracked excavators) is precision-manufactured. As the high-pressure establishment and core fuel supply assembly of the entire common rail system, it bears the heavy responsibility of continuously pressurizing low-pressure diesel fuel and stably delivering it to the common rail cavity, providing precise and consistent pressure support for each cylinder.

Adhering to the manufacturing standards of "high-pressure steady-state output, precision wear resistance, and durability," the pump body is made of high-strength forged alloy steel. The internal plunger assembly and fuel metering valve are made of specially quenched bearing steel, with a high-density, ultra-wear-resistant coating on the surface, effectively preventing internal scoring and pressure leakage caused by diesel impurities. After installation, mechanics and operators will experience a significant upgrade: crisp and rapid cold start; rapid and stable oil pressure build-up at low idle speeds; and responsive and sensitive throttle pedal and control lever under full-load climbing, frequent starts, or heavy-load operation conditions, resulting in smooth acceleration and continuous power delivery, completely eliminating stalling and vibration caused by insufficient fuel supply, and providing a smooth and stable driving experience.

High-intensity operation scenarios for engineering infrastructure and large tunneling equipment: Engineering excavators and construction vehicles continuously tunnel under high loads in muddy and dusty environments, placing extremely high demands on the stability and response speed of the high-pressure oil pump. When the equipment experiences starting difficulties, slow oil pressure build-up at idle, or stalling under increased load, on-site technicians promptly replace it with this high-pressure oil pump. After replacement, the oil pressure build-up is stable and rapid, and the engine power output is tight and brisk, ensuring continuous and efficient construction operations. Intercity express delivery and short-haul heavy-duty freight scenarios: Medium and heavy-duty trucks and commercial buses are often fully loaded, requiring the engine to continuously provide stable high torque output in the low-speed range. When vehicles experience weak acceleration or insufficient fuel pressure leading to reduced power during uphill driving, the maintenance team promptly updates the high-pressure fuel pump assembly. A stable and powerful fuel pressure supply restores the engine's full power, easily handling frequent start-stop cycles and heavy loads, ensuring continuous and efficient transportation operations.
