が高くなり、これを圧力センサ６が検知して作動する。In the above-mentioned conventional device, diesel/mother ticulate, which is an incompletely combusted component discharged from the engine 1, becomes suspended matter in the exhaust gas and is captured by the filter 4 via the idazost manifold 2 and the connecting pipe 3. Only some of the diesel 7 ticulates and exhaust gas that cannot be collected are released into the atmosphere from the exhaust pipe 5. As the amount of collected diesel fuel increases, the exhaust pressure increases, and the pressure sensor 6 detects this and operates.

る。At the same time, the controller 7 operates the heating device 9 based on signals such as the exhaust temperature and throttle opening detected by the temperature sensor 8, and the heat from the heating device 9 is transferred to the filter 4 through the connecting pipe 3.
In addition, the diesel nozzle ticulate deposited on the filter 4 is incinerated and removed. As this incineration progresses, the pressure of the exhaust gas decreases, so the pressure sensor 6 stops operating, and the heating device 9 stops depending on conditions such as temperature and throttle opening.

４の破損等の不具合が生じた。However, in the above-described conventional particulate purification device, since the heating station 9 is located upstream of the filter 4, the accumulation of diesel particulates reaches the heating device 9, which prevents the heating device 9 from working. The exhaust pressure of the engine 1 increased, causing problems such as a decrease in the output of the engine 1 and damage to the filter 4.

It is an object of the present invention to provide a diesel particulate purification device that does not cause problems in exhaust gas by heating and removing diesel particulates without being located.
