description

As the core fuel injection component of FAW Xichai diesel power, 0445120323 endures long-time high-pressure diesel scouring, frequent load alternation and strong mechanical vibration during long haul and mountain transportation. Ordinary injectors tend to get nozzle blocked and valve assembly degraded under continuous heavy load, which leads to poor atomization, incomplete combustion and obvious power loss on uphill. This injector is specially calibrated to match Xichai engine performance parameters, adopting high-strength alloy steel and reinforced control valve assembly. Precisely machined nozzle creates fine fuel mist to raise combustion efficiency. Optimized internal oil circuit stabilizes injection timing and fuel delivery, reducing back-leakage risk after prolonged running. Reinforced integrated construction resists cyclic pressure impact and vibration. Every finished injector passes bench inspection of fuel flow, spray pattern and durability test to reliably replace aged OEM injectors

advantage

・OEM Consistent Mounting Dimension: Manufactured according to original installation benchmark, mounting holes and outer contour fully match OEM spare parts, supporting direct swap without secondary machining or manual adjustment.
・Calibrated for Mountain Heavy Load: Tuned for Xichai engine high torque feature, maintains stable injection effect under repeated climbing and poor fuel quality.
・Matched Sealing Repair Kit Attached: Brand-new sealing accessories are supplied together, meeting maintenance and overhaul demands without extra purchasing.
・Batch-wise Bench Testing: Every batch passes flow deviation test, spray morphology inspection and durability verification, ensuring consistent performance between batches.
・Reinforced Anti-Wear Valve Group: Upgraded valve assembly resists erosion from fuel impurities and cyclic pressure impact, slowing internal wear and extending service life under heavy haul.

FAQ 

Q1: What faulty symptoms can this 0445120323 injector solve?

A: It improves common faults caused by nozzle carbon coking and internal component wear, including insufficient climbing power, unstable idle speed, black smoke during acceleration, slow throttle response and abnormal fuel consumption rise.

Q2: What engines and vehicles is 0445120323 suitable for?

A: It is specially adapted for FAW Xichai diesel engines, widely fitted on FAW Jiefang heavy trucks for long-distance transportation.

Q3: Is ECU coding required after installation?

A: Most Xichai vehicles support plug-and-play direct replacement. Individual updated ECUs need corresponding injector code input to achieve optimal fuel supply matching.

Q4: What are the key installation precautions?

A: Flush fuel rail and pipelines thoroughly to remove residual impurities; install brand-new sealing parts; ensure dust-free assembly environment; perform idle and heavy-load test after installation and check all joints for fuel leakage.
