    摘要： An ignition apparatus for a combustor (10) includes a broadband laser energy source (30) that emits laser energy into the combustor (10), the broadband laser energy having at least two fundamental wavelengths, to produce a plasma that ignites a combustible mixture therein. In one embodiment, laser energy in the ultraviolet and infrared regions are emitted into the combustor (10). Intensity and time characteristics for the laser energy including fluence, pulse duration, repetition rate, peak intensity and average intensity can also be controlled for one or more of the fundamental wavelengths to further enhance the ignition and combustion processes.

    摘要： Apparatus for igniting fuel in a combustor (10) is disclosed. The combustor has at least one fuel nozzle (16) which emits an atomized fuel spray into a primary zone (20) of the combustion chamber. A laser energy source (44) produces infrared laser energy and an optic fibre cable (46) transmits the laser energy from the laser source into the primary zone (20) of the combustor (10) to ignite the fuel spray via a laser igniter (30). In one embodiment, the laser igniter (30) is disposed in a main fuel nozzle of the combustor.

    摘要： An exciter for an internal combustion engine igniter plug includes a charging circuit (104) and a discharge circuit (106). The charging circuit is connected to a power supply (108) and the discharge circuit is connected to the plug (64) to produce sparks. The discharge circuit (106) comprises a storage capacitor (38) connected to the charging circuit (104), a gated solid state switching device (33-35) connected between the capacitor (38) and the plug (64), and a trigger means for gating the switching device on and off. The capacitor is discharged when the switching device (33-35) is gated on and is charged by the charging circuit (104) after the switching device is gated off.
