PURPOSE: A fuel nozzle preventing clogging phenomenon and changeable a filter is provided to prevent a nozzle filter from being clogged and smoothly perform the filtering while improving the fuel efficiency by preventing a carbide from being deposited at an end part of the fuel nozzle. CONSTITUTION: A fuel nozzle comprises a hollow nozzle body(10) which a main fuel feed pipe(14) and a pilot fuel feed pipe(16) are respectively extended from an end thereof, a hollow insert(18) which is inserted into the nozzle body, communicated with the pilot fuel feed pipe, and which main fuel is flowed at the surface thereof and pilot fuel at the center, a pilot nozzle(30) connected to the other end of the nozzle body, forming a pilot fuel injection hole at the center, and forming at least one main fuel through hole around the pilot fuel injection hole, a main nozzle(20) formed at the front end of the pilot nozzle to inject the main fuel passing through the main fuel through hole, a main filter(40) inserted into the main fuel feed pipe, and a pilot filter(50) inserted into the pilot fuel feed pipe.
