Patent ID: 11156148

Abstract:
An active prechamber device may include a prechamber housing longitudinally aligned with a main axis. The active prechamber device may also include a prechamber nozzle forming a cap at an end of the prechamber housing. The prechamber nozzle and prechamber housing may define a prechamber space that extends along the main axis. The prechamber nozzle may have a plurality of orifices fluidly connected to the prechamber space. Additionally, a fuel injector may be in a linear arrangement with the prechamber housing along the main axis. The fuel injector may have a fuel injection nozzle positioned to spray a fuel into the prechamber space. An electrode arrangement may be formed within the prechamber space. The electrode arrangement may include an electrode shaft and an electrode ring. The electrode ring may circumscribe the electrode shaft to form a spark gap within the prechamber space.
