Abstract:
An igniter for an internal combustion engine is disclosed. The igniter may have a body, and a pre-combustion chamber integral with the body and having at least one orifice. The igniter may also have at least one electrode associated with the pre-combustion chamber. The at least one electrode may be configured to direct RF energy to lower an ignition breakdown voltage requirement of an air and fuel mixture in the pre-combustion chamber. The RF energy alone may be insufficient to ignite and sustain combustion of the air and fuel mixture. The at least one electrode may also be configured to generate an arc that extends to an internal wall of the pre-combustion chamber and ignites the air and fuel mixture.
