(57) [Summary] [PROBLEMS] To accurately detect an abnormality in a discharge state due to adhesion of soot or dew condensation water on the surface of an insulator flow path. SOLUTION: An insulation resistance detection terminal 21 for detecting a resistance value of an upstream end face of the insulator flow path 13 while laminating a plurality of flow path structures 12 made of an insulator having a plurality of insulator flow paths 13 is provided. 22 is arranged. Focusing on the fact that as the amount of soot and dew water adhering to the surface of the insulator flow path 13 increases, the resistance value of the surface of the insulator flow path 13 decreases and the discharge state deteriorates. Before the start and / or the period during which the discharge can be stopped during the operation of the engine, the insulation resistance detection terminals 21 and Resistance value between the two (resistance value of the upstream end face of the insulator flow path 13) Is detected, and the discharge state is determined based on the resistance value. If it is determined that the discharge is abnormal due to the adhesion of soot during the operation of the engine, the air-fuel ratio of the exhaust gas is temporarily controlled to be rich to burn off the soot attached to the insulator flow path 13. |
