Abstract
A prechamber device for facilitating a combustion reaction within a combustion chamber of an internal combustion spark-ignition gasoline engine includes a prechamber body, first and second electrodes, an insulation, first and second electrode terminals, a spark plug, and a prechamber head. The prechamber body includes orifices and at least partially contains the combustion reaction. The insulation insulates the first electrode and the second electrode from the prechamber body. The first electrode terminal receives a first amount of power and the second electrode terminal receives a second amount of power from an energy storage device. The first and second electrode terminals deliver the power to the first electrode and the second electrode that generate the electric field. The spark plug generates an ignition arc to initiate the combustion reaction. The prechamber head retains a position of the spark plug and closes off a first end of the prechamber body.
