Maintenance of Fuel Nozzles


The durability and efficiency of your vehicle engine depends on atomized and distributed fuel. When it comes to the condition of a fuel nozzle, it contributes more to the particular situation than other parts in the engine. The recommendation of the manufacturer on fuel nozzle removal is commonly accepted up to 400 hours. Generally, maintenance shops recommend less than 400 hours and some even as low as 100 hours.

Whether your aircraft is properly equipped with a PT6A or a TPE331 engine, dirty nozzles can cause voids and streaks in the atomized fuel entering your combustion chamber. In some cases, they may burn holes in stators or turbine wheels. 

At overhaul, it is necessary that fuel nozzles should be properly cleaned and completely disassembled. Another important thing that you should keep in mind is that all baked-on hydrocarbons and contaminated should be removed. This is done by the use of pyroltic cleaning, heated ultrasonic cleaning, heated chemical baths, and other "State-of-the-Art" techniques.

Features of Fuel Nozzles:

  • Comfortable handling – It is easier to handle the fuel nozzle without much expertise. In many filling stations, fuel nozzles are used extensively.
  • Extremely high flow rate – Due to the high flow rate, this type of nozzle offers great efficiency.
  • Easy installation – The installation process of fuel nozzle is easier and you can do so by following a few easy steps.
Apart from those features, fuel nozzles have some other features as well. Some of them include the following: 

  • Compact designs
  • Corrosion resistance
  • Fixed orientation
  • Pull push actuation
  • Robust construction
