description

0445111005 serves as the core common rail injection unit of construction machinery diesel engines. During non-stop site operation, sustained high-pressure fuel washing, frequent load alternation and violent machine vibration gradually create micro-wear on spray holes and fatigue damage to internal valve assemblies. This impairs injection accuracy, reduces combustion efficiency and causes progressive power loss. Optimized to meet SG04 heavy-duty engineering equipment standards, this injector adopts high-strength wear-resistant alloy steel plus reinforced anti-fatigue valve assembly. Its precision-manufactured nozzle generates fine and uniformly spread fuel mist to achieve full combustion inside cylinders. Refined control valve optimizes injection timing and fuel metering precision, minimizing internal leakage and pressure drop risks. Reinforced internal structure withstands repeated cyclic high-pressure impact. Each finished injector passes strict high-pressure cycle testing, atomization inspection and dimensional calibration to directly replace aged and malfunctioning injectors.

FAQ

  • Q1: What operational symptoms can this replacement injector resolve?
  • A: This replacement injector fixes multiple abnormal conditions triggered by internal component aging and wear. Typical issues include weak engine pulling power, rough idling performance, visible black exhaust smoke under acceleration, hard cold‑start performance in cold climate, delayed pedal response and unexpectedly high diesel consumption.
  • Q2: Which engine and vehicle units suit part number 0445111005?
  • A: It is purpose‑built for construction machinery diesel engines. Widely fitted for crawler excavators, wheel loaders, road rollers and concrete pump trucks.
  • Q3: Is injector coding or ECU programming necessary after installation?
  • A: Most vehicles support straightforward drop‑in replacement. Certain vehicle control units do demand injector code input to attain optimum combustion efficiency and running performance.
