description

0445120080 is the core fuel injection component of Korean Doosan diesel engines. During long‑term field engineering operation, continuous high‑pressure diesel scouring and frequent load switching cause gradual nozzle micro‑wear and internal valve fatigue, reducing injection accuracy and combustion efficiency, and leading to progressive power loss. Optimized per SG04 industrial heavy‑duty standards, this injector adopts high‑toughness wear‑resistant alloy steel and reinforced anti‑fatigue valve assembly. Its precision nozzle produces uniform fine fuel mist for full cylinder combustion, while the upgraded control valve stabilizes injection timing and fuel volume consistency, lowering internal leakage and pressure drop risks. The reinforced structure resists cyclic high‑pressure impact. Every finished unit passes strict high‑pressure durability, atomization and dimensional calibration tests for direct replacement of aged original injectors.

FAQ

  • Q1: What typical faults can this injector solve? A: It repairs common faults caused by long‑term injector aging, wear and internal fatigue. It effectively solves weak acceleration, poor climbing power, jittery idle, heavy black smoke during acceleration and loading, difficult cold start in low temperature, delayed ignition, slow throttle response and excessive fuel consumption, restoring stable engine operation.
  • Q2: What engine and models does 0445120080 fit? A: This common rail injector is specially calibrated for Korean Doosan diesel engines. It widely fits most mainstream Doosan construction machinery.
  • Q3: What are the key installation precautions? A: Clean dirt and metal impurities in fuel rails and pipelines to prevent nozzle blockage. Replace new sealing gaskets to avoid oil leakage and air intake. Keep a clean assembly environment and follow standard installation procedures. Test idle stability and acceleration performance after installation.
  • Q4: How to prolong service life? A: Use high‑quality clean diesel to reduce nozzle wear and carbon buildup. Replace fuel filters regularly to block impurities. Avoid sustained overload operation and frequent load changes. Keep fuel pipelines clean and well sealed to maintain optimal injector performance.
