0445120081 Injector Assembly for FAW Xichai 6DF

0445120081 acts as the core fuel injection component of FAW Xichai 6DF diesel engines. In long-term heavy-duty construction and highway transportation scenarios, the injector endures continuous high-pressure fuel scouring, frequent load changes and severe vibration, which easily cause nozzle micro-wear and internal valve assembly fatigue damage, resulting in reduced injection accuracy, incomplete combustion and gradual power attenuation. Optimized for Xichai 6DF heavy-load working conditions, this injector adopts high-rigidity wear-resistant alloy steel and reinforced anti-fatigue valve structure. The precisely machined nozzle achieves uniform and delicate fuel atomization to ensure sufficient in-cylinder combustion. The upgraded control valve improves injection timing and fuel metering precision, effectively avoiding internal leakage and pressure loss. The reinforced integral structure resists long-term cyclic high-pressure impact. Every finished injector has passed strict high-pressure cycle tests, atomization detection and dimensional calibration, which can perfectly replace old and failed injectors.
