Abstract: PROBLEM TO BE SOLVED: To provide an ignition timing control method and device for a premixed compression ignition engine of simple structure.
SOLUTION: The ignition timing control device for controlling the ignition timing of the premixed compression ignition engine 10 has a laser generators 1, 1' for generating predetermined laser beams 2, 2'; a condensing irradiation means 3 for condensing and irradiating predetermined laser beams generated from the laser generators 1, 1', toward a combustion chamber 7 of the premixed compression ignition engine 10. The condensing irradiation means 3 condenses and irradiates the predetermined laser beams 2, 2' toward the combustion chamber 7 to produce an oxygen radical (O*). 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.
