ABSTRACT:
According to the present ivention, a combustion chamber of internal combustion engines comprises: a main combustion chamber which is created by recessing the piston top; a swirl chamber which is contiguous to said main combustion chamber via a passage; and a fuel injection nozzle to supply atomized fuel into said main combustion chamber and swirl chamber. Because of the above arrangement, a relatively quick combustion takes place in the swirl chamber and a relatively sluggish combustion takes place in the main combustion chamber. As a result, the generation of HC, NOx, or smokes are suppressed while improving an output, a fuel consumption rate, and a thermal efficiency.
