description

As the core fuel injection component of FAW Xichai diesel power, 0445120345 withstands continuous high-pressure diesel scouring, frequent load changes and strong mechanical vibration during long-distance highway haulage. Ordinary injectors easily suffer nozzle clogging and valve group degradation under heavy-duty cycles, resulting in uneven atomization, incomplete combustion and obvious power drop under heavy load. This injector is specially calibrated to match Xichai engine performance characteristics, adopting high-strength alloy steel and reinforced control valve assembly. Precisely machined nozzle generates fine fuel mist to boost combustion efficiency. Optimized internal oil circuit stabilizes injection timing and fuel delivery volume, reducing back-leakage risk for long-hour operation. Reinforced integrated construction resists cyclic pressure shock and vibration. Every finished injector passes bench inspection of fuel flow, spray pattern and durability test for reliable substitution of aged OEM injectors.

advantage

・Calibrated for Xichai Heavy-duty Application: Tuned for FAW Xichai engine, maintains stable injection performance under heavy climbing and inferior fuel quality.
・Whole-Unit Replacement Reduces Equipment Downtime: Complete assembly replacement simplifies on-site repair steps, shortens vehicle idle period and cuts fleet operation cost.
・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 for long-haul heavy trucks and coaches.

FAQ 

Q1: What faulty symptoms can this 0445120345 injector solve?

A: It improves common faults caused by nozzle carbon coking and internal component wear, including insufficient power under heavy load, unstable idle speed, exhaust smoke, slow throttle response and abnormal fuel consumption rise.

Q2: What engines and vehicles is 0445120345 suitable for?

A: It is specially adapted for FAW Xichai diesel engines, widely fitted on FAW heavy-duty trucks and large coaches.

Q3: 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.

Q4: How to extend injector service life for heavy trucks and coaches?

A: Use qualified diesel fuel and replace fuel filter on schedule; avoid long-time continuous full-load operation; reduce frequent sharp acceleration; keep fuel system clean to reduce impurity abrasion inside the injector.
