description

0445110537 serves as the core common‑rail injector for construction machinery diesel engines. During harsh site operation, long‑term high‑pressure fuel scouring, continuous heavy load and strong mechanical vibration easily cause nozzle micro‑wear and internal valve fatigue, leading to declined injection accuracy, rough combustion and gradual power loss. Optimized in accordance with SG04 heavy‑duty standard, it adopts high‑rigidity wear‑resistant alloy and upgraded anti‑fatigue valve structure. Precision nozzle generates uniform fine mist to achieve sufficient cylinder combustion. The optimized control valve improves injection timing and fuel metering accuracy, lowering risks of internal leakage and pressure loss. Reinforced internal structure withstands continuous high‑pressure impact and vibration. Every finished injector passes strict high‑pressure cycle, atomization and dimension inspection for direct replacement of old units.
