A swirl chamber used in association with a combustion chamber for diesel engines, includes a pair of sub-nozzle holes on the opposite sides of a main nozzle hole to supply a secondary air into the swirl chamber, the sub-nozzle holes being positioned such that the secondary air ejected therethrough is fully utilized for the combustion in the swirl chamber, thereby securing the complete combustion and the reduction of environmental contaminants such as NOx and fumes.
