LEAN-BURN METHOD USING PLASMA JET

摘要

The present invention relates to a lean combustion system using a plasma jet. More specifically, the lean combustion system using a plasma jet of an ignition plug comprises: a positive electrode (10) of a metallic material having a shaft which is a middle electrode and receiving a high voltage; a plurality of negative electrodes (20) separated from the positive electrode (10) in a radial direction; and a dielectric barrier unit (30) of a nonmetallic material enclosing outer circumferential surfaces of the negative electrodes (20) and exposing one ends of the negative electrodes (20) to the outside. A prescribed voltage is applied to the positive electrode (10) to induce dielectric barrier discharge (DBD) to generate a plasma jet which moves along the surface of the dielectric barrier unit (30) to be released.
