Provided is an after-treatment device for the exhaust gases of a combustion chamber, which device comprises a discharge unit having electrodes exposed to the combustion chamber and disposed in at least one of members constituting the combustion chamber, an antenna disposed in at least one of the members constituting the combustion chamber so as to emit electromagnetic waves to the combustion chamber, an electromagnetic wave transmission passage which is formed in at least one of the members constituting the combustion chamber and has one end connected with the antenna and the other end covered with an insulator or a dielectric element and extending to and connected with a portion of a cylinder block or a cylinder head apart from the combustion chamber, and an electromagnetic wave generating unit for feeding electromagnetic waves to the electromagnetic wave transmission passage. The after-treatment device is configured to discharge from the electrodes of the discharge unit, while exhaust gases are left in the combustion chamber after the exhaust gases are produced at an explosion stroke, thereby emitting the electromagnetic waves fed from the electromagnetic wave generating unit through the electromagnetic wave transmission passage, from the antenna. |
