  "textContent": "An ammonia-fueled engine based on oxygen enhancement and reactive activity control, and an ammonia-rich combustion control method thereof are provided. The ammonia-fueled engine based on oxygen enhancement includes a jet ignition device and an ammonia gas injector. An oxygen injector is provided on the jet ignition device. During the operation of the ammonia-fueled engine, the ammonia gas injector firstly injects ammonia fuel into a combustion chamber, and ammonia gas in the combustion chamber enters a prechamber inner cavity through a jet hole during a compression stroke, and the oxygen injector firstly injects oxygen gas into a prechamber to reduce an ammonia concentration in a gas mixture in the prechamber, dilute the gas mixture in the prechamber, improve the reaction activity of the gas mixture, and ensure the speed and intensity of an initial flame; and then a jet flame is formed to ignite over-concentrated ammonia-air mixture in the combustion chamber.",
