ABSTRACT:
A method for a laser ignition system to operate in at least two modes based on a four-stroke combustion cycle, wherein laser light energy is generated to ignite an air/fuel mixture for combustion and may be additionally used for heating cylinder walls, such as during a cold start, at times other than when the laser ignites an air/fuel mixture for combustion.
