This fuel injector nozzle meters and atomizes fuel into the engine combustion chamber. It is the terminal component of the fuel system, receiving pressurized fuel from the injection line and delivering it as a fine spray for proper combustion. A worn or carbon-fouled nozzle disrupts the spray pattern, causing incomplete combustion, reduced power, and increased exhaust smoke. As an original AGCO component, it is machined to the same flow-rate tolerance and spray-angle specification as the factory-fitted part, ensuring the injection timing and cylinder pressure remain within design parameters.
