Abstract:
1. A laser ignition system for an internal combustion engine including a combustion chamber, the laser ignition system comprising: at least one laser light source configured to generate a laser beam, wherein the laser beam is transmitted along a path extending from the at least one laser light source directly to the combustion chamber; and an optical beam guidance component configured to transmit the laser beam to irradiate on an oxygenated fuel mixture supplied into the combustion chamber at a region of highest ignitability to generate a combustor flame in a flame region, wherein the optical beam guidance component is configured to provide mechanical alignment of the at least one laser light source and an ignition port formed in a combustor wall of the combustor chamber and to cooperatively transmit a light emission from the combustor flame along a same path as the laser beam; and a flame sensor and control diagnostic component housed integral with the at least one laser light source and configured to detect at least a portion of the light emission and operable to control one or more combustion parameters based in part on the detected light emission.
