摘要:
An object 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 includes a dielectric body and at least two barrier discharge electrodes which are held inside the dielectric body and to which voltages for barrier discharge are applied, wherein each of the barrier discharge electrodes are not exposed to the inside of a cylinder bore and are arranged so as to surround the cylinder bore.

A plasma actuator (1) includes four electrodes (11) and three dielectrics (10) and is disposed on the side of an object surface (B). When a high voltage is applied to the electrodes (11), a plasma (15) is generated at an end (10a) of each dielectric (10) exposed so as to be accessible to a gas. In the plasma actuator (1), the electrodes (11) and dielectrics (10) are alternately stacked one on another. The plasma actuator (1) includes a stepped exposed portion (X). The plasma actuator (1) in which the electrodes (11) and dielectrics (10) are arranged such that the ends (10a) of the dielectrics (10) are exposed in the normal line direction of the object surface (B) in the stacked order in the stepped exposed portion (X) can suppress the flow of the generated plasma even when the plasma actuator is exposed to a high-speed airflow under high pressure. This stabilizes the plasma.

An exhaust gas purification apparatus 4 includes a plasma reactor 7 having gas flow passages 28 through which exhaust gas is to pass, and a power source 8 for supplying power to the plasma reactor 7 with a variable application voltage and/or a variable frequency of the application voltage of the power to be supplied. The exhaust gas purification apparatus 4 is adapted to change the application voltage and/or a pulse recurrence frequency of the application voltage, based on a change in amount of PM and/or flow rate of gas passing through the gas flow passages 28. Accordingly, efficient oxidization of PM in the exhaust gas and suppression of consumption of discharged power are achieved.
