Abstract
In an apparatus and method for controlling a combustion process, the output of an optical parametric oscillator/laser (OPOL) is directed into the combustion chambers of an internal-combustion engine to initiate combustion of an air/fuel mixture. A control unit controls the output of the OPOL to emit a wavelength of radiation within a region of absorption of the molecules of the air/fuel mixture in order to induce those molecules into a state of excitation to ignite the mixture. The exact wavelength of the OPOL is selected based on the type of fuel and the compression ratio of the engine. A cylinder-firing-control (CFC) unit is responsive to signals transmitted by the control unit to direct the output of the OPOL to selected cylinders of the engine. And a sensor is mounted on the engine for transmitting signals to the control unit indicative of the rotational position of the engine, and the control unit controls the firing of the OPOL based on these signals.
