Enhanced combustion for spark ignition engine using electromagnetic energy coupling

摘要

A method of improving the combustion of a spark-ignition internal combustion engine. Such engines have at least one cylinder, each cylinder having a compression chamber and operated such that an air-fuel mixture introduced into the combustion chamber is ignited to cause a combustion event. An antenna is placed within the combustion chamber, and is used to apply electromagnetic energy to the combustion.

1. A method of improving the combustion of a spark ignition engine, the engine having at least one cylinder, each cylinder having a combustion chamber and a piston that reciprocates within the combustion chamber, comprising:
locating an antenna within the combustion chamber; providing an air-fuel mixture into the combustion chamber; igniting the air-fuel mixture with an igniter, such that a combustion event occurs; delivering an electromagnetic signal to the antenna; wherein the antenna applies electromagnetic energy into the combustion chamber near the time of the combustion event; adjusting, during the combustion event, the frequency of the electromagnetic energy in response to changing dimensions of the combustion chamber as the piston moves with the combustion chamber.
