Abstract:
An internal combustion engine includes a combustion chamber formed by cooperation of a cylinder bore formed in a cylinder block, a cylinder head and a piston. A combustion ignition device is disposed in the combustion chamber and includes a nozzle defining a pre-chamber, a barrier discharge plasma igniter, including a tip portion disposed in the pre-chamber and a plurality of apertures disposed in the nozzle. The pre-chamber is in fluidic communication with the combustion chamber via the plurality of apertures. A controller is in communication with the engine and the barrier discharge plasma igniter.
