Here’s a comparison on the advantages and disadvantages of the different types of fuel nozzles:
| FUEL NOZZLE | ADVANTAGES | DISADVANTAGES |
| SIMPLEX NOZZLE | Produces excellent atomization at high fuel flow and pressure. | Low engine speeds and high altitudes result in poor performance. |
| DUPLEX NOZZLE | In comparison to the simplex nozzle, the duplex nozzle provides more efficient atomization across a wider range of flow rates. | It employs a more intricate mechanism than the simplex nozzle since it needs a flow divider. |
| SPILL TYPE NOZZLE | Allows for the return of excess fuel to the inlet nozzle. Even at high altitudes and limited fuel flows, it is possible to achieve efficient atomization. | Susceptible to generating a strong fuel-to-air combination |
| VARIABLE PORT NOZZLE | Has a device that regulates the amount of fuel discharged via the aperture. | The process is too complicated, and particles can interfere with it. |
| AIR SPRAY NOZZLE | It helps to prevent initial carbon production by converting fuel into air particles. | Can’t be a standalone nozzle and it has higher possibility of contamination |
