An improvement of a swirl type fuel atomizer is disclosed in which a plurality of notches are equiangularly formed around an opening of a single-nozzle hole so that the liquid fuel injected may be divided into a plurality of fuel spray patterns. The complete combustion with a relatively low temperature may be ensured so that the emission of nitrogen oxides may be substantially eliminated or reduced.
