178-0199 Fuel Injector 3126 For CAT Engine

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.

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.

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.

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.

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.
