Key Features
-
Micron‑Level Orifice Precision: Accurate spray‑hole machining, uniform fine fuel mist, improve combustion efficiency, reduce black smoke and carbon deposit inside cylinder.
-
High‑Wear‑Resistant Alloy Material: Surface hardening treatment, anti‑abrasion and anti‑corrosion, adapt to heavy‑load harsh working environment of construction machinery.
-
Strict Flow‑Rate Consistency: Each nozzle is flow‑tested, stable fuel delivery, guarantee balanced cylinder working status after assembly.
-
1:1 OEM Dimension Standard: Fully interchangeable with original nozzle, no modification needed during injector reassembly and overhaul.
-
Cost‑Effective Machinery Overhaul Solution: Replace only nozzle instead of whole injector, effectively cut maintenance cost for excavator fleets and repair workshops.
Solvable Common Faults
-
Poor fuel atomization and fuel dripping from nozzle tip
-
Engine insufficient power and weak digging performance under load
-
Heavy black smoke emission and incomplete diesel combustion
-
High fuel consumption caused by nozzle wear or carbon blockage
-
Rough idle, engine shaking and mis‑firing
-
Difficult cold start triggered by nozzle performance degradation
