  • Publication number: 20250146449
    Abstract: An ammonia-rich combustion coupled dual-mode prechamber ammonia-fueled engine control system is provided, including an ammonia-fueled engine and an electronic control unit. The ammonia-fueled engine includes a combustion chamber, a dual-mode jet ignition device, and an ammonia injector. The dual-mode jet ignition device includes a prechamber, an air injector, and a fuel injector. When the engine operates, ammonia fuel is firstly injected into the combustion chamber by the ammonia injector to form a rich ammonia-air mixture with air in the combustion chamber. During a compression stroke of the engine, the rich ammonia-air mixture in the combustion chamber is entered into the prechamber through a jet hole. The air injector performs scavenging in the prechamber until a equivalence ratio of prechamber gas mixture is less than 1.0, and then the fuel injector injects fuel into the prechamber forming target mixture. Finally, the target mixture is ignited by the spark plug.

  • Publication number: 20250149976
    Abstract: In an embodiment, during an overload or short circuit condition, a current limit circuit of an inverter is utilized in a pulse-by-pulse manner, which in turn causes the AC output of the inverter to operate in a hiccup mode (e.g., pulse-by-pulse based on and off dependent upon the output current) and automatically recover once the operating parameters (e.g., output current) are within the proper ranges. The pulse-by-pulse current limit circuit is configured to protect the switching circuits of the inverter from shorting or device failure during any peak operating voltage conditions by ensuring on/off timing accuracy of the inverter.
