BARRIER DISCHARGE DEVICE

摘要

One of the purposes of the present invention is to provide a barrier discharge device capable of increasing the combustion efficiency of an engine while overcoming the problems of the cumbersome replacement of the electrodes and the commercialization of the device. The barrier discharge device of an engine has a dielectric body and at least two barrier discharge electrodes which are held within the dielectric body and to which voltages for barrier discharge are applied. Each of the barrier discharge electrodes is not exposed to the inside of a cylinder bore and is disposed so as to surround the cylinder bore.
