Abstract: A laser ignition system for an internal combustion engine, and more specifically a gas turbine engine, is provided. The system comprises at least one laser light source configured to generate a laser beam and an optical beam guidance component. The optical beam guidance component is 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. The system further includes an integrated control diagnostic component configured to detect at least a portion of a light emission and operable to control one or more combustion parameters based in part on the detected light emission. The system further includes additional enhanced ignition control configurations. A method for igniting a fuel mixture in an internal combustion engine is also presented.

Abstract: The present application and the resultant patent provide a waste heat recovery system. The waste heat recovery system may include a first organic rankine cycle system, a second organic rankine cycle system, and one or more preheaters. The preheaters may be one or more charge air coolers. The charge air coolers may be in communication with the first organic rankine cycle system, the second organic rankine cycle system, or both the first organic rankine cycle system and the second rankine cycle system.

Abstract: A laser ignition system for an internal combustion engine, and more specifically a gas turbine engine, is provided. The system including a laser light source configured to generate a laser beam, an ignition port configured to provide optimized optical access of the laser beam to a combustion chamber and an optical beam guidance component disposed between the laser light source and the ignition port. The optical beam guidance component is configured to include optimized optic components to transmit the laser beam to irradiate on a fuel mixture supplied into the combustion chamber to generate a combustor flame in a flame region. A method for igniting a fuel mixture in an internal combustion engine is also presented.

Abstract: The present application and the resultant patent provide a waste heat recovery system for recovering heat from a number of turbocharger stages. The waste heat recovery system may include a simple organic rankine cycle system and a number of charge air coolers in communication with the turbocharger stages and the simple organic rankine cycle system. The charge air coolers are positioned in a number of parallel branches of the simple organic rankine cycle system.
