Particulates in the exhaust gas discharged by the exhaust gas pass through the exhaust manifold 2 and the exhaust pipe 3, and are filtered by the filter 5 housed in the filter housing 4, where they are accumulated in the filter 5. When particulates accumulate in the filter 5 to a certain extent, the pressure in the exhaust manifold 2 increases and the fuel efficiency of the diesel engine 1 deteriorates, so in this case, the filter 5 must be completely regenerated.
一般にパーティキュレイトの主成発番１カーボンであシ
その着火温度Ｊ″１５００℃前後である。Generally, the main constituent of particulates is carbon No. 1, and its ignition temperature J'' is around 1500°C.

５の再生を行う。Therefore, if the temperature of the filter 5 in which particulates have been accumulated is raised to y]1-500° C. or higher by some method, the particulates will be burned off and the filter 5 can be regenerated. In the case of FIG. 1, fuel is combusted in the burner 9, the combustion exhaust gas is mixed with the engine exhaust gas, and the temperature of the engine exhaust gas is raised to 500°C or more, thereby indirectly raising the temperature of the filter 5. Play step 5.

The filter 5 is regenerated by feeding it into the engine exhaust gas in the exhaust pipe 3.

シ、フィルタ５會安定に再生し難かった。However, the above device had the following drawbacks. (
1) High pressure that can overcome exhaust pressure (usually 0.8~/
Since the air pump 11 and the fuel pump 10' have large flow rates (usually 100 t/- or more) and large flow rates (usually 100 t/- or more), the devices are large, require a large amount of electricity, and are expensive. (2) Since the exhaust pressure fluctuates depending on the operating state of the engine, it is necessary to control the air pressure and fuel pressure, which is troublesome. (3)
Combustion within the burner 9 was unstable due to fluctuations in exhaust pressure, and it was difficult to regenerate the filter 5 in a stable manner.

去される。Next, microwave power is supplied from the microwave oscillator 8 to the filter housing 4 via the microwave supply path 7 . The microwave reflecting plate 6 is made of, for example, a metal mesh or a cross-shaped metal plate, and reflects microwave-type chips, but fluids such as air and exhaust gas can pass through it without pressure loss. Therefore, the supplied microwave power exists only within the filter housing 4. On the other hand, oxygen necessary for oxidizing particulates is supplied from the exhaust gas flowing throughout the filter housing 4. Due to the nature of microwaves, the microwave power inside the filter housing 4 is absorbed only by the particulates deposited on the filter 5.
Each batch is selectively heated. In this way, the particulates are heated above their ignition point, oxidized and burned, and the filter 5 is regenerated. When the regeneration is completed, the solenoid valve 15 is closed, and the exhaust gas from the engine 1 follows only the exhaust gas branch pipe 3a and is discharged from the muffler 3. This state continues until the next regeneration is performed, and the particulates in the exhaust gas are removed. is deposited on the filter 5 and removed from the exhaust gas.

Further, it is not necessary to completely align the axes of the microwave supply path 7 and the filter 5, but it is possible to arrange the filter 5 and the microwave supply path 7 so that they are effectively sandwiched between the two microwave reflection plates 6. Good. Further, when the engine is a gasoline engine, the combustion is performed at a leaner than stoichiometric mixture ratio when the filter 5 is regenerated, which has the same effect as the above embodiment.
