Estimating the term…
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.
An ammonia-fueled engine based on oxygen enhancement, comprising a jet ignition device (4), a piston (1), a cylinder head (7), a cylinder liner (8), and an ammonia gas injector (5), wherein a combustion chamber (2) is formed between the piston (1) and the cylinder head (7), and an end of the jet ignition device (4) and an end of the ammonia gas injector (5) extend into the combustion chamber (2);
