The present invention relates to a method for initiating and maintaining premixed compression ignition combustion, and provides a method for operating a combustion apparatus 10 including an engine 12 and an air treatment unit 14. In this method, in the air treatment unit 14, the intake air is separated into oxygen-enriched air and nitrogen-enriched air, and the oxygen-enriched air is supplied to the engine 12 to start premixed compression ignition combustion. A step of reducing the amount of oxygen-enriched air supplied to the engine 12 to maintain premixed compression ignition combustion. |
