Since only the condensing irradiation of predetermined laser beams toward the combustion chamber is carried out, the conventional premixed compression ignition engine has only to be provided with a laser light source for generating laser beams, and a condensing irradiation means for condensing and irradiating the laser beams. Structure can thereby be made extremely simple.
