description

0445120059 acts as the core fuel injection unit for Cummins SAA6D107E-1 diesel engines. During long-time construction site operation, persistent high-pressure diesel scouring, repeated load switching and mechanical vibration gradually create micro-wear on spray holes and fatigue degradation inside valve assemblies. This undermines injection accuracy, reduces combustion efficiency and leads to gradual power attenuation. Optimized to meet SG04 heavy construction machinery specifications, this injector adopts high-toughness wear-resistant alloy steel plus reinforced anti-fatigue valve sub-assembly. Its precisely machined nozzle generates fine and evenly distributed fuel mist to achieve sufficient in-cylinder combustion. The upgraded control valve stabilizes injection timing and fuel metering consistency, effectively lowering risks of internal leakage and pressure drop. Reinforced internal structure withstands cyclic high-pressure impact. Every finished injector passes strict high-pressure cycle durability test, atomization inspection and dimensional calibration to directly replace worn and aged original injectors.
