98F12303001000 is a specialized aerospace engine fuel nozzle cleaning and testing GSE (Ground Support Equipment), compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for large commercial turbofan engines. It is used to clean the fuel nozzles and test their spray performance during on-ground maintenance, which is critical for ensuring the fuel nozzles can atomize fuel evenly, optimizing the combustion efficiency of the engine's combustion chamber, avoiding incomplete combustion that may cause carbon deposition or reduced engine thrust.

Made from high-strength stainless steel and precision flow-detecting components, it operates stably in -10°C to 110°C ground environments. Weighing 1.1kg with quick-connect fuel interfaces, it allows for fast and accurate cleaning and testing during fuel system MRO. It is an essential tool for engine combustion system maintenance.
