description

0445110796 acts as the core common rail fuel injection component of construction machinery diesel engines. In actual field operation, long-lasting high-pressure fuel washing, sharp load fluctuations and strong machine vibration gradually create micro abrasion on spray holes and fatigue damage to internal valve groups. This impairs injection accuracy, lowers combustion efficiency and results in continuous power decline. Optimized in compliance with SG04 off-highway heavy-duty criteria, this injector adopts high-toughness wear-resistant alloy steel and reinforced anti-fatigue valve assembly. Its precisely processed nozzle generates fine and evenly distributed fuel mist to guarantee full combustion inside cylinders. The upgraded control valve optimizes injection timing and fuel metering accuracy, minimizing internal leakage and pressure loss risks. Reinforced internal structure withstands repeated high-pressure impact under heavy loads. Each finished injector passes strict high-pressure cycle testing, atomization inspection and dimensional calibration for direct replacement of aged and failed 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 0445110796?
  • A: It is purpose‑built for construction machinery diesel engines. Widely fitted for excavators, wheel loaders, compactors and various kinds of off‑highway engineering equipment.
  • 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.
  • Q4: What essential points should technicians observe during fitting?
  • A: Fully flush away dirt and residue inside fuel rails and connecting pipelines. Always mount brand‑new sealing gaskets. Keep the whole assembly area dust‑free. After finishing installation, carry out idle‑speed test and acceleration inspection to verify working status.
