1. High-Strength Alloy Forged Body
The injector main body adopts high-precision alloy steel integral forging, outstanding high temperature and ultra-high pressure resistance. Stable long-term full-load operation performance under construction and mining harsh environments, no deformation or internal fuel leakage.
2. Original HEUI Hydraulic Electronic Control Nozzle Assembly
Equipped with HEUI hydraulic electronic injection structure and micro multi-hole precision nozzle, multi-stage variable injection control. Each injector passes strict flow, atomization and dynamic balance testing before delivery, uniform fuel atomization, improves combustion efficiency, reduces black smoke and nitrogen oxide emissions.
3. 100% OEM Dimensional & Calibration Standard
Fully complies with CAT original machining and calibration standards, internal oil channel size and electromagnetic control parameters consistent with OEM injectors. Direct plug-and-play replacement without ECU parameter modification, perfectly matched with CAT 3126 engine.
4. Multi-Layer High Pressure Composite Sealing System
Multi-layer fluorine rubber sealing rings are installed on all oil circuit joints, with excellent oil resistance, high temperature resistance and anti-aging performance. Effectively block internal and external fuel leakage, extend injector service life and reduce maintenance frequency.
5. Optimized Power & Fuel Economy Performance
Accurate control of injection timing and fuel delivery volume, effectively solve engine insufficient power, unstable speed, excessive fuel consumption and exhaust black smoke faults. Maintain original power output of 3126 engine, reduce cylinder liner and piston wear.
Delivery: Multiple global shipping channels including air and sea freight. Each injector is individually oil-sealed with anti-collision foam packaging, complete inspection documents and traceable tracking number. All products pass hydraulic pressure and atomization test before shipment.
Import duties, local consumption taxes and extra handling fees are not included in quoted price and freight. Buyers shall bear all related fees in accordance with local customs regulations.
This heavy-duty HEUI diesel fuel injector is specially designed for CAT 3126 engine with OEM part number 178-0199, widely used in CAT 322C, 325C excavators and heavy trucks. It adopts alloy forged body, original HEUI control structure, precision multi-stage injection nozzle and factory original calibration data, fully reaches OEM matching standard. It is the core replacement spare part for engine overhaul, effectively reduce equipment downtime and long-term maintenance costs.
