Question: 1 / 400

How is the flow range of the fuel discharge nozzles installed in a fuel injected reciprocating engine indicated?

By a letter stamped on the hex of the nozzle body

By a number stamped on the hex of the nozzle body

The flow range of fuel discharge nozzles is indicated by a number stamped on the hex of the nozzle body because each nozzle is designed to provide a specific range of fuel flow to the engine. A letter stamped on the nozzle may refer to the manufacturer or material, but does not indicate the flow range. The code on the engine data plate may provide information about the type of nozzles installed, but it does not give the specific flow range. The color coding on the nozzle tip is used for identification purposes and does not necessarily indicate the flow range. Therefore, the number stamped on the hex of the nozzle body is the most accurate way to determine the flow range of fuel discharge nozzles in a fuel injected reciprocating engine.
