When the exhaust gas of the engine (1) passes through the exhaust pipe (2) and is introduced into the electrostatic precipitator (3), the carbon particles in the exhaust gas are collected in the electrostatic precipitator (3). The action causes it to be collected on its surface. As a result, harmful carbon particles are removed from the exhaust gas that passes through the muffler (12) and is released into the atmosphere. By the way, when the engine (1) is operated for a long time, a large amount of carbon particles are deposited on the surface of the electric heater (4), and the deposited carbon particles and the discharge electrodes (5) and (5a) are separated.

, (5a), and (5b) spark discharge begins to occur. The discharge current due to this spark discharge is detected by a spark discharge detector (7), and the frequency of occurrence of the spark discharge is detected by an electronic control device (10). At this time, when the amount of deposited carbon particles increases and, as a result, the frequency of occurrence of the spark discharge becomes higher than a predetermined value, the electromagnetic switch (8) is driven by the electronic control device (10) and turned on, and the electromagnetic switch (8) is turned on. Electric current is supplied from (9) to the electric heater (4). As a result, the carbon particles deposited on the surface of the electric heater (4) are heated and burned and removed. After this predetermined time has elapsed, the electromagnetic switch (8) stops operating and is turned off, so that the electrostatic precipitator (3) again performs the action of collecting carbon particles in the exhaust gas, and this operation is controlled electronically. This can be done automatically by the device (10).
